Bembidium undulatum, Sturm. There are now about thirty-eight species of Carabidæ recognized as indigenous to North America and Europe, and some of them also to Asia. The most of these are arctic or very northern, this being one of the few that occur in temperate America, but now far northward it inhabits is unknown, as I know only of its occurrence here, though in Europe and Asia it is found in sub-arctic regions. Here it is taken abundantly in July and August under decaying vegetation in most alluvial places subject to occasional inundation. It is a Notaphus, .20 inch long, shining, elytra obscurely rufo-piceous, paler at apex with oblique pale mark, punctures of striæ obsolete behind middle and surface undulated. Identical with European specimens, and also verified by Dr. Horn.

Egg.—Conodial, round-topped, nearly as broad at base as high, the top depressed; marked by about 19 thin, elevated, vertical ribs, one half running from base to summit, the others but four fifth or more the distance; the spaces between crossed by many low horizontal ridges; the micropyle surronded by two or three circles of very fine depressions, outside of which are rows of very large four or five-sided depressed cells; color yellow-green. Duration of this stage about ten days.

Cucullia Hartmanni, n sp.

Expanse 1.75 inches, length of body .75 inch. General color of fore wings pale gray, so suffused in places with dark gray as to give the wings a moderately dark gray cast, but not so dark as C. intermedia, Spey. Lines black, basal half line only indicated on the costa. T. a line double; the inner part almost imperceptible; strongly dentate, from its origin projecting obliquely outward to a strong tooth on the fold in the discal cell, with a short tooth on the fold between the costal and subcostal veins; from discal tooth it receds to median vein a little nearer the body than its inception on the costa; from this it extends out in another tooth nearly twice as far out as the discal tooth, the point resting on the submedian fold, almost reaching the infection of the t.p. line, the points of both lines nearly obsolete in a white patch at this place that fades out into the general color; about the middle of the space from teh median vein to submedian fold a brownish black spur is sent our parallel with the median vein, terminating above the middle of the white patch; the line reaches the posterior margin by another inflexoon on submedian vein, and another outward tooth below the vein.

6. Brachynemurus nigrilabris Hagen. N. sp.

Very similar to B. peregrinus. Face yellow, above with a large black band, which is rounded below and reaches nearly the clypeus; this band is going between and around the antennæ and connected above with the black part covering the whole anterior half of the vertex; posterior half yellow with a broad black longitudinal band, dilated angularly in middle; the angle sometimes protracted on each side in fine line, which does not reach the eyes; labrum shining black; palpi yellow, last joint of the maillary cylindrical black; labials a little longer, last joint shining black, fusiform, sharply pointed, less inflated than in B. peregrinus.

I have received from the author a copy of this pamphlet in which a large number of North American species and genera are somewhat briefly described in anticiption of the publication of a general Monograph. That M.Ragonot is in a situation to materially increase our genral knowledge of the group cannot be doubted. He has long collected types and specimens, and has studied the characters of the Old World genera. I have deprecated the description of Phycidæ without giving the full structural characters, and in so far as this has been do I agree with M. Ragonot's introductory remarks.

It has occured to me to say a few words upon the subject of author's types. It sometimes happens that a specimen is labelled “type,” which is not the true type, i. e., the one (or ones) from which the original description was drawn up and which accords with that description. This is the criterion for types, that they do not contradict the original description. The late Mr. Morrison sent me at one time a “type” of Harris's Agrotis tessellata. Upon my wonder at his having such a specimen, I found it was merely a compared example, but it shold not have been labelled “type”.

I wish to draw particular attention to this genus and its allies. I have, in 1865, drawn a parallel between the group and the Hawk Moths, from the young stages and the peculiar pupation, and in my pamphlet on “the Hawk Moths of North America,” I hae discussed the probabilities of their relationship. But I here wish to point out that the group is American; that in America we may except to find old types among that portion of the fauna which is indigenous, pre-tertiary, and to this Citrheronia belongs.

The task of preparing and illustrating a work upon the Butterflies of Japan, after the model of Mr. Distant's Rhopalocera Malayana, has been undertaken by Mr. H. Prye, of Yokohama, who with persistent enthusiasm for the past seventeen years has been engaged in collecting the Lepidoptera of the Empire, and studying their habits. The work, entitled Rhopalocera Nihonica, will appear in three parts, 4to.
