PTEROSTICHIN.E 33 J 



This species differs from validus in its shorter and broader form, 

 less elongate elytra, total absence of the feeble longitudinal impres- 

 sion near the hind thoracic angles, paler legs and paler antennae. 



Hypherpes anthrax n. sp. Nearly as in the preceding in outline but 

 more elongate, deep black, the legs black, the anterior tarsi feebly rufes- 

 cent; elytra slightly alutaceous in the female; head nearly as in responsor, 

 the mandibles smaller and black, the antennae piceous-black; prothorax 

 similar in outline to that of responsor throughout, except that the base is 

 transverse medially, or only vestigially sinuate, and is margined through- 

 out except at the middle; surface with the ruguliform lines more evident, 

 the impressions very feeble; inner fovea long, deeply though obtusely 

 impressed, the outer much shorter but distinct, forming a distinct carina 

 between it and the sides; elytra three-fourths longer than wide, a fourth 

 wider than the prothorax, the sides parallel and evenly arcuate; apex 

 less obtusely rounded than in responsor, somewhat as in validus, the 

 humeral denticles minute and subobsolete, the sinus almost completely 

 wanting; striae and intervals nearly as in the preceding, the short scu- 

 tellar stria similarly deep; prosternum almost similar. Length (9 ) 13.5 

 mm.; width 5.0 mm. Vancouver Island (locality unrecorded). 



Allied to validus, but differing very much in the strong short 

 sulcus near the hind thoracic angles and denning a distinct carina; 

 in validus there is a short feeble impression in this position, usually 

 not attaining the base and not delimiting a carina; the body is 

 more elongate than in responsor and the mandibles are much smaller, 

 resembling those of validus. 



Hypherpes restrictus n. sp. Small and narrow, moderately convex, 

 shining, the elytra micro-reticulate but not dull; color rufo-piceous to 

 nearly black, the legs black, the femora rufous; head slightly elongate, 

 with distinctly prominent eyes, two-thirds as wide as the prothorax, the 

 sulci strongly arcuate; mandibles moderate; antennae not very stout, 

 black, gradually ferruginous distally; prothorax but slightly though evi- 

 dently wider than long, the sides subevenly rounded and finely reflexed 

 throughout, straighter and oblique basally to the minutely prominent 

 angles, which are more than right, owing to the rounding at the sides of 

 the base, the latter distinctly narrower than the apex, sinuate medially 

 and feebly margined laterally; apex moderately sinuate, with blunt 

 angles; impressions evident but feeble, the surface also with subobsolete 

 ruguliform lines; inner fovea moderate, not attaining the base, the outer 

 a barely visible short impression, the carina wholly wanting; elytra two- 

 thirds longer than wide, only a sixth wider than the prothorax, regularly 

 rounded behind, the sides feebly arcuate; humeral denticles minute; sub- 

 apical sinus extremely feeble; striae rather fine, moderately impressed, 

 minutely, closely and obscurely punctulate at the bottom, the scutellar 

 short, fine and feeble to wholly obsolete, the ocellate puncture always 

 completely wanting; intervals very feebly convex; prosternum faintly 

 impressed along the middle, the process not distinctly margined. Length
