Previous to the present year noctuid moths were collected for breeding purposes and flight records, in various ways, entailing long hours spent in the field at night. The methods employed were variations of the old practice of “sugaring” and collecting from bloom. Fairly good results were obtained by systematic night collections, but it seemed desirable to devise a method whereby material might be secured in sufiicient quantities without so much night work. During the past winter the trap under discussion was designed and constructed as an experiment towards simplifying moth collections and flight records.

Some time ago, through the kindness of Mr. Tams of the British Museum, I was enabled to have specimens compared with the types of dealbana Wlk. and similisana Wlk. and the genitalia of both types examined. The result is a confirmation of Heinrich's placement in his revisioni, dealbana falling to glaciana Moesch. and similisana to bipartitana Clem.

The fauna of Utah is unusually rich in Diptera. Much remains to be done by way of recording the forms that occur in this area and in learning the distribution of the economic forms within the state. The following records are from recently classified material of the Utah Agricultural Experiment Station collection. The writer is indebted to Messrs. J.M. Aldrich, C.H. Curran, C.T. Greene, R.H. Painter, and J.S. Hined for naming most of the material listed below.

Owing to their general similarity the species of this genus have been much confused and for some time we have been accumulating material in the hopes of being able to straighten out the nomenclature. With the exception of intermedius Eaton from Arizona, which is entirely unknown to me, I find I can now satisfactorily tie down the existing names and incorporate therefore in the present paper the result of my studies.

Female. Dark brown in colour; 2.37 mm. long, 2.62 times as long as wide; allied to various Schedl.

Front flattened on a semicircular area below, rather finely moderately closely punctured, interspaces finely rugose, with very fine, inconspicuous hairs and with a distinctly but not strongly developed longitudinal carina which extends up to a level of the middle of the eyes; antennae concolourous, club 1.65 times as long as the funicle, 1.33 times as long as wide, first suture straight, second feebly arcuate, third strongly arcuate; eyes moderately coarsely granulate, the inner line emarginate, emargination wider than deep.

The following new species of Arenetra have come to hand in working over some miscellaneous material in the Canadian National Collection. The genus Arenetra is referable to the tribe Lissonotini as defined by Cushman and Rohwer (Proc. U. S. N. M., 57, 392, 1920). The characters mentioned by Ashmead (Proc. U. S. N. M., 23, 50, 1900) will aid in separating species of Arenetra from related genera. Of importance among these are the non-areolated propodeum, sessile abdomen, distinct areolet, non-pectinate tarsal claws and long erect whitish or black pile on the head and thorax.

For the past several years live moths have been collected at the Entomological Laboratory, Lethbridge, Alta. for the purpose of securing eggs. Both light trap and bait have been used to make these collections.
