Diplocheila (Isorembus) oregona Hatch
Rembus oregonus Hatch, 1951 : 119; [type specimen a male, in coll. of Melville H. Hatch, U. of Washington ; allotype and one other paratype in Hatch coll.; 5 paratypes in coll. K. and D. M. Fender.]. Type locality: McMinneville, Oregon (determined from original description).
In addition to the diagnostic characters mentioned in the key and in connection with the diagnosis of the preceding species, oregona differs from all other species of the striato punctata group in having the microgranulation of the elytra coarser, and the micropunctures of the pronotum so small as to be readily overlooked at a magnification of 54 diameters. The elytra seem to lack micropunctation.
Variation. — Data on variation in length, width, and number of spines in the posterior median row of the hind tibiae are presented in tables 17-19. There is slight variation in convexity of the eyes, and of the elytral intervals. The elytral striae of the Utah specimens are slightly shallower than average, and are impunctate. In all of the other specimens examined the striae are finely punctate. In 21 specimens the basal portion of stria 1 is indicated very feebly, sometimes as a broken line, but not joined to the sutural portion of 1. In two specimens from Medicine Hat, one from the Cypress Hills, and one from Jenner, Alberta, the basal portion of stria 1 is joined to the sutural portion, and the sutural stria is free. However, the basal portion of 1 is weakly
developed in the latter group of specimens. In the remaining specimens there is no indication of the basal portion of stria 1, and the scutellar and sutural portions of 1 are joined.
The genitalia and retractile plates were not examined.
Synonymical Notes. — Charles Schaeffer used three different label names for this species : Rembus brevicomis, carri, and parvus but failed to publish any of these. These specimens, bearing holotype labels, are in the collection of the United States National Museum. In the Le Conte Collection, Rembus impressus no. 5 collected in Oregon, is a member of this species. This name was not published by Le Conte.
Distribution. — The range of this species is the northern portion of the Plains, from Winnipeg, Manitoba northward to Edmonton, Alberta, southward into " Utah " and " Nevada ", and westward across the mountains to western Oregon.
Twenty-two males and fifteen females, collected in the following localities, have been examined.
Alberta : Cypress Hills, Edmonton, Jenner, Medicine Hat, Redwater, Tothill. Manitoba : Winnipeg. " Nevada ". Saskatchewan : Regina. " Utah ".
