In a region where heavy rains constitute an elenlent of the climate, it is imperative that all creatures meet these exigences with protective responses. The responses of many insects to rain are very interesting. Naturally their activities are usually favored by fair weather and sunshine. During, rains many insects withdraw to protected places and await the return of sunshine to begin their activities.

Resembling calliandrus in size and form but light with vertex slightly acute and twice banded with ivory. Length 4 mm.

Vertex slightly acute but shorter, broader than in loricatus with a rounding apex, only slightly exceeding the pronotum in length. Color: grey much lighter than in calliandrus with the appearance of three or four transverse light bands, the first of which, half way between the eyes and apex of vertex, is made up of an ivory semi-circle around a dot on the margin, on either side and two pairs of dashes between these: the second is on tlie basal third of vertex; the third across the scutellum and soinetimes a narrow one on the disk of pronotum.

During a recent study of the material in the family Phryganeidae in the Canadian National Collection, three nondescript species of the genus Prophryganea ganea Martynov have appeared. One of them, viz. P. deflata nov., is so close to P. improba (Hagen) as to be inseparable on any but the genitalic character illustrated herewith. As the range of P. deflata is very much that of P. improba (Hagen), it is questionable if the five ♂ co-types of the latter are conspecific; that one therefore which was deposited in the Canadian National Collection some years ago by Doctor Nathan Banks, is here designed lectotype, and its genitalia and alar nervation illustrated. This specimen and the genitalic slide are being returned for deposition in the Cambridge Museum of Comparative Zoology.

During the last few years' collecting in British Columbia, certain new species of Coleoptera have accumulated, until the writer now has a sufficient series of each to warrant their description.

To Mr F. Johansen I am indebted for a small collection of Corixidae obtained by dissecting the stomach of a 28 centimeter male specimen of the Arctic Grayling (Thymallus signifer Richards.) captured in a small tributary near the mouth of the Churchill River, Manitoba. Three species are represented, one of which is described below.

General ground color yellowish white to semihyaline. Color markings orange to red. Vertex with three white spots more or less surrounded with bands of color. Pronotum with almost rectangular median band touching pasterior margin and semblance of vitta from each anterior corner toward anterior margin, usual marks behind each eye. Scutellum with spot at tip, basal angles yellow more or less bordered with red or orange.
