12 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 94 



Fifth sternite about seven-eighths as long as broad. Ventral edge 

 of hind tibia emarginate. 



Rostrum stout, upper surface subcontinuous with head in profile, 

 median carina reaching from base to nasal plate. Antenna about as in 

 convergens. Prothorax about as long as wide, widest before middle, 

 sides more strongly rounded than in convergens, and slightly con- 

 stricted near apex, faintly so near base ; pronotum medially sulcate, 

 general surface rather densely clothed with broad, striated scales, 

 which toward middle do not entirely conceal the small, shiny black, 

 setigerous tubercles or granules, the latter joined here and there (and 

 especially each side of sulcus), with irregular carinae, the scales 

 denser toward sides. Elytral costae with a crowded row (double for 

 the most part) of posteriorly inclined setae similar to those in con- 

 vergens, second and fourth intervals without setae except near base 

 and apex, sixth with a widely spaced single row, serial punctures and 

 scales about as in convergens. Beneath scaly and setose, the abdominal 

 scales dense basally, somewhat sparser on third and fourth sternites, 

 and replaced by inclined setae on apical portion of fifth sternite; 

 intercoxal piece relatively broader and not so deeply impressed as in 

 J* convergens; femora, especially hind pair, shorter and stouter than 

 in convergens; hind tibia broadly emarginate on ventral edge from 

 basal three-sevenths to apex, the posterior face in apical half flattened, 

 shiny, and sparsely setose ; mid tibia similarly but mure feebly modi- 

 fied, fore tibia sinuate ; fore and mid tibiae denticulate on ventral 

 edge; hind tibial mucro (^ broad, flattened, and faintly curved, the 

 apex rounded. 



Type locality. — Forest Grove, Oreg., June 18, 1923; i (^. 



Type.—U.S.'^.M. no. 50648. 



The unusually long fifth sternite, the structure of the hind tibia, 

 and the subspatulate hind tibial mucro distinguish the male of this 

 species from that of convergens.
