My last paper on the Coleoptera of Florida mas prepared in the autumn of 1927, and published in the Canadian Entomologist for March, 1928. I spent the winter of 1927-28 in California and did not return to Florida until November, 1928. During the winter of 1928-29 circumstances were such that I did little collecting, and that only about Dunedin, until March, when I made a visit to Gainesville, Fla.

The insects of this genus are all North American and are strikingly distinct from all other forms in this region in their almost hemispherical outline and leathery opaque elytra. Although they jump with great agility, when seen strutting about on their broadly foliaceous legs they appear awkward and grotesque in the extreme. They rest on the stems of the shrubs head upwards and the body inclined outwards at about a 30-degree angle.

Length 6-6.3 mm. ; width 2.6-2.7 mm. Oblong, moderately convex and elongate, parallel. Black; the legs and elytra very dark reddish brown, almost black; shining.

During the summer of 1929, Mr. W. J. Brown collected numerous specimens of Hemiptera at various stations on the north shore of the Gulf of St. Lawrence from Trinity Bay, Que. eastward to the Labrador boundary. Though the number of species obtained is not large, the distributional records are of considerable interest in that they extend the recorded distribution and add further data on the boreal and holarctic tendencies of certain groups.

The literature contains but few definite records of Corixidae from Eastern Canada although many species have been described from adjacent territories and without doubt are present in the Canadian fauna. Recent collecting at various points in Ontario and Quebec has resulted in procuring new records for several species of Arctocorixa. The following constitutes a preliminary list of the Arctocorixa species of this region.

In the routine work of sorting and determining Aquatic Hemiptera from the western United States, I was quite surprised recently to discover two new species in genera which I supposed were fully known. In a lot consisting of 110 Ranatra tahen by Doctor R. H. Beamer and his parties on the Biological Survey trips into the southwestern United States during the last two or three years I found one specimen of a very distinct and new species.

This paper records the Hemiptera of the superfamily Scutelleroidea (Burmeister) now in the collection of the Utah Agricultural Experiment Station. The writers wish to thank Dr. E. P. Van Duzee for his kindness in determining a series of specimens, by comparison with which the remainder of the collection was named. The purpose of this list is to give additional information as to the occurrence, distribution, abundance, and note damage by the forms of economic importance.

The genus Polmacorixa was erected by Abbott (Ent. News, XXIII, 337, 1912) for a single species, Palmacorixa gillettii Abb. described from three males and three females collected at Fort Collins, Colorado, during May and June, by Professor C. P. Gillette. Subsequently (Can. Ent., XLV, 113, 1913) Dr. Abbott described a second species, Palmacorixa buenoi Abb. from specimens taken at White Plains, New York, during August and September, by Mr. J. R. de la Torre-Bueno. A third species, Palmacorixa mexicana Hungfd. has been described by Dr. H. B. Hungerford (Pan-Pac. Ent., IV, 94, 1927) from a pair of specimens collected in the Xochimilco Sea, Mexico, by Dr. A. Dampf.

Description of the adult female. Dark brown in colour; 2.00 mm. long, 2.62 times as long as wide, allied to ponderosae Blackm.

Front of the head plano-convex below, closely, moderately finely punctured, coarser and sparsely on vertex, the interspaces between the punctures minutely reticulate; longitudinal carina moderately strongly developed and elevated, extending from the slightly arcuate epistomal margin up to a level of the upper angle of the eyes; indistinctly clothed with short yellow hairs.

A very interesting collection of Ephemeroptera was brought back to Ottawa by Mr. W. J. Brown who spent the entire summer of 1929 on an insect faunal survey along the north shore of the Gulf of St. Lawrence, the survey extending from Trinity Bay in the west, where the fauna is still typically Canadian and Hudsonian, to Bradore Bay at the entrance to the Straits of Belle Isle, where the conditions are very similar to those found on the Labrador coast.

A milky-white species, sometimes tinged with yellow, with four red stripes on elytra. Allied to D. cruentata. Length 2.75-3 mm.

In “Wasp Studies Afield” we recorded the enormous mortality of these hibernating queens in the crevices of rocky bluffs. Since that record was made, on half a dozen different occasions, I have found handfuls of dead wasps on the window-sills of several club-houses.

A study of the distribution of mosquitoes from Colorado discloses many areas which have not as yet been reported. Among the collections we find only one report of Anopheles and its identification has been uncertain. Cockerell lists seventeen species of mosquitoes from Colorado or Wyoming. Among these is listed Anopheles quadrimaculatus Say taken at Hotchkiss and Delta in Delta County by G. P. Weldon and recorded by Howard, Dyar, and Knab. He states: “We have so far found no trace of Anopheles in our collections.”

Mr. C. A. Frost, the coleopterist, to whom of recent years I have been indebted for many interesting and, indeed, rare Heteroptera, has again favored me with some unusual species taken by him this summer (1929), in Nova Scotia. Portaupique, so I learn from Mr. Frost, is on the North shore of Minas Basin, 30 miles west of Truro; Westchester is up in the hills at a lake in the spruce woods.

The identity of Scotogramma oregonica Grote has always been a matter of some doubt to taxonomists. Smith gave his idea of the species in a paper entitled “Notes on Mamestra trifolii Rott. and Its Allies” (1910, Ent. News, XXI, 357); Wolley-Dod (1913, Can. Ent., XLV, 31) surmises a mixture of species in Grote's type lot of material and states that the male type in the Neumoegen Collection at Brooklyn (now incorporated in the U. S. Natioonal Museum) is the same as Smith's morana (op. cit., p. 361) ; following Dod morana was made a variety of oregonica in the 1917 Barnes and McDunnough Check List.

In an earlier paper (1925, Trans. Am. Ent. Soc., LI, 184) brief reference was made to larvae of Platyptilia fragilis in the seed-capsules of Pentstemon cyananthus, one of the common perennials of the sagebrush association. The presence of the larvae in the seed-capsules while feeding is not apparent, although a large portion of the seeds contained therein are eaten.

In early June of the summer of 1928 an immature nymph of the genus Cinygma was dredged from tlie sedges along the edge of a mill pond at Horning's Mills, Ontario. All attempts to get more material here were unsuccessful. Next year, however, on June 7, I met with some full-grown nymphs in a deep rock-pool by the edge of a stream which flows into Lake Nipissing, Ontario from the south. About fifteen individuals were reared between the 10th and the 20th of June and the species proved to be Cinygma bipunctata McD. The description of the type fits these individuals very well.

The Dolichopod herewith described belongs to a genus containing a large number of species having very similar form. The new form is related to tristis Loew but is readily distinguished by the wholly black legs.

In working over nzaterial received for identification from S. C. Bruner and G. N. Wolcott, the following new species were found.

The following list is compiled from specimens collected by Mr. W. J. Brown in 1929; it should prove of interest to students of geographical distribution, containing, as it does, large elements of the Labrador fauna on the one hand and typical members of the Canadian and Hudsonian zones on the other. As far as I know Wm. Couper has been the only one who has published on the Lepidoptera of this region (Can. Ent., I, 67; IV, 201; VI, 33 et seq.) and his work has been confined largely to diurnals.
