BYRRHID/E 25 



and perditus with the size materially smaller, more parallel and less 

 convex than in criddlci; head moderately developed, densely punc- 

 tate, the transverse inter-ocular line represented only by its two 

 subfoveiform extremities; prothorax nearly half as long as its basal 

 width, of the usual form but with the median line distinctly canalic- 

 ulate throughout the length, the punctures everywhere minute and 

 very close; vestiture moderate in length and density, the fulvous 

 hairs predominating and forming a few more condensed lines, two 

 of which inclose an irregular median rhomboid; scutellum with dense 

 brownish-black hairs: elytra nearly one-half longer than wide, paral- 

 lel, with feebly arcuate sides, the latter rounded and converging in 

 apical third to the obtusely sublobiform apex; pubescence short, 

 coarse, not dense, dark brown, but little variegated by darker con- 

 densation on the alternate intervals, the crescentiform area inclosed 

 by very feebly denned pale fulvous spots and unusually large, its 

 sutural length two-fifths as long as the suture; abdominal asperities 

 small but strong, moderately close. Length (cf) 7.0 mm.; width 

 3.9 mm. Labrador (Xain) torpidus n. sp. 



10 Abdomen strongly, closely and very confusedly punctato-rugose, 

 the basal segment coarsely punctate medially. Form more nar- 

 rowly oblong-oval, not very deep black throughout; head moderately 

 developed, convex, strongly, densely punctate, the transverse line 

 and pale spots obsolescent, the pubescence rather abundant, coarse, 

 fulvous and black, conspicuous; prothorax evidently less than half 

 as long as the basal width, the sides only moderately converging 

 and nearly straight, the punctures small but deep and perforate, 

 becoming gradually somewhat smaller and closer medially, the 

 surface everywhere rather shining, the vestiture rather coarse, vari- 

 egated; scutellum densely nigro-pubescent; elytra rather more than 

 a fourth longer than wide, parallel, almost evenly rounding in about 

 apical third, the short vestiture rich dark fulvous in color, the alter- 

 nate intervals with dense and more blackish vestiture, the two 

 inner vittce scarcely at all broken; metasternum strongly, densely 

 punctate throughout, except a small elongate smooth spot on the 

 median line just behind the middle, the median smooth line not 

 indicated; mesosternal sinus shallow. Length 6.0 mm.; width 3.5 

 mm. Oregon callidus n. sp. 



Abdomen with fine and more distinct asperate punctulation, the basal 

 segment never more than rather finely punctate medially; form 

 much more broadly oval 1 1 



1 1 Form rather short, oblong-oval, very convex, black, the under surface 

 and legs just visibly picescent; head rather small, convex, densely 

 punctate, inconspicuously pubescent, the transverse line obsolete 

 but with three small shining spots in short transverse line between 

 the eyes; prothorax formed nearly as in the preceding and with rather 

 long black vestiture, which forms a few linear aggregations, the medial 

 elongate rhombus distinct, the paler hairs very few and inconspic- 

 uous, the punctures fine and dense; elytra about a fifth longer than 

 wide, parallel and feebly arcuate at the sides, very obtusely rounded 

 in about apical third, the hairs abundant, almost entirely black, the
