Il8 CASEY 



Body nearly similar in form, rather strongly shining throughout, pale 

 piceo-rufous, the elytra, under surface, legs and antennae still 

 paler, ferruginous — possibly partially owing to immaturity; — 

 pubescence abundant and conspicuous posteriorly though only 

 moderate in length as in tvickhami ; head somewhat coarsely and 

 closely punctate thi'oughout, the sinus broadly angulate, the lobes 

 rounded, impressed; anterior canthus rather broadly rounded, 

 visibly less prominent than the posterior ; prothorax fully three- 

 fourths wider than long, the sides broadly rounded and strongly 

 converging anteriorly, becoming parallel and nearly straight in 

 about basal half, the apex rather shallowly sinuate, fully two- 

 thirds as wide as the base, the angles right and only slightly 

 blunt; surface very finely, rather closely punctate, becoming 

 coarsely and unusually densely so very broadly toward the sides, 

 the bead fine ; basal angles slightly prolonged, right ; scutellum 

 moderate; elytra one-half longer than wide, the sides gradually 

 converging and broadly, evenly arcuate from slightly behind the 

 middle to the narrowly parabolic apex, nearly smooth, finely, 

 rather sparsely, submuricately punctate, becoming rather coarsely, 

 densely, muricately so, with the punctures transversely subcon- 

 fluent, laterally ; prosternuni strongly, closely punctate, the process 

 nearly circular in form behind the very strong intercoxal constric- 

 tion, unmargined except moderately along the coxcE ; femora and 

 abdomen as in ivickhami \>wt less strongly punctured. Length 

 1 1.2 mm. ; width 5.4 mm. Washington State — pubifera n. sp. 



Wickhami is a larger species than obtusa, with much less 

 transverse prothorax and angulate, and not broadly rounded, 

 elytral apex ; the posterior part of the elytra in -pubifera differs 

 again from anything else known in the group, and this is an 

 unusually well differentiated species, in which the pale colora- 

 tion is in all probability not entirely due to immaturity, a parallel 

 case being J'af-alloiii'ca, of the following group. 



Group VII. — Type eschscholtzi. 



This is one of the larger groups of the genus, and, at the same 

 time, one of the most restricted in habitat. It occurs exclu- 

 sively in the coast regions from San Francisco Bay probably 

 through Oregon, being geographically coincident with the 

 viatica group ; to the northward and eastward of this region it 

 is replaced b}' the sctosa and ovalis groups, and, to the south- 

 ward, by the ahdominalis group. The species are oblong or 

 oblong-suboval, usually strongly convex in form and generally 

 have very coarse and deep elytral punctures, separated by 

 convex interspaces, giving to the surface a more or less pro-
