than the prothorax and three and one-half times as long, rather finely but 

 strongly, only moderately closely punctate, the pubescence very short, decum- 

 bent, even and sparse, with scarcely a trace of longer subserial hairs f °). 

 Length 2.6 mm.; width 1.0 mm. Lake Superior. — A male specimen from 

 Siskiyou Co., California, is attached for the present and may belong to this 

 species, as the differences presented are all in directions shown by other series to 



be sexual in origin depressulus, sp. nov. 



25 — Nodes of the thoracic angles small but very prominent, forming a narrow uneven 

 convex surface sharply pointed behind ; body rather narrow, elongate, moderately 

 convex, black, the head and pronotum slightly piceous, the antennae and legs 

 rufo-piceous ; pubescence rather sparse, coarse, suberect, the subserial bristles 

 long and distinct ; eyes small, the antennal club moderate ; prothorax not very 

 transverse, one-half to three-fifths wider than long, not very coarsely but deeply 

 and densely punctate, the callous spots subobsolete ; meuian denticle short but 

 rather broad, acute posteriorly, the sides thence moderately convergent and 

 broadly arcuate to the base, the width across the denticles slightly greater than at 

 the apical nodes ; elytra elongate-oval, slightly wider than the prothorax and more 

 than three times as long, the punctures moderately coarse, deep and ,not very 

 close-set ( $? ). Length 2.3 mm.; width 0.83 mm. Utah (southwestern) and 



Colorado porrectus, sp. nov. 



Nodes of the thoracic angles not notably prominent 26 



26 — Antennae long, rather stout and unusually developed, about half as long as the 

 body, the club moderate ; eyes moderate ; body quite short and stout, oblong- 

 oval, pale rufo-ferruginous in color throughout, the pubescence conspicuously 

 long, coarse, suberect and bristling, rather abundant and subeven ; prothorax 

 large, as wide as the elytra, three-fourths wider than long, evenly convex, 

 coarsely, but not very closely, punctured, the callous spots subobsolete ; nodes 

 large, almost as long as the distance thence to the acute denticles, narrow and 

 shining sublaterally ; elytra one-half longer than wide, between two and three 

 times as long as the prothorax, coarsely but not very closely and in part subseri- 

 ally, punctate, very minutely so toward apex ( $ ). Length 1.8 mm.; width 0.8 



mm. Michigan antennatus, sp. nov. 



Antennoe much shorter, always much less than half as long as the body 27 



27 — Eyes very small and strongly convex, scarcely a third as long as the head ; body 

 large, rather stout, elongate-oval, pale flavo- testaceous in color throughout, the 

 pubescence only moderately long but suberect, very abundant and conspicuous, 

 the subserial hairs but little longer and not very distinct ; antennal club moderate ; 

 prothorax well developed, two-thirds to three-fourths wider than long, evenly 

 convex, finely, deeply and closely punctured, the callous spots subobsolete, the 

 sides parallel and evenly rounded from base to apex, the spicules very minute, 

 the nodes well developed but narrow, polished, with a small central puncture ; 

 elytra elongate-oval, rather narrowly rounded behind, two-thirds longer than 

 wide, obviously wider than the prothorax, the punctures fine and unusually close- 

 set ; male and female almost completely similar in form throughout, the former 

 very slightly less stout. Length 2.6-2.9 mm -5 width 1. 05-1. 2 mm. Pennsyl-
