Punctures strong and moderately coarse more or less close-set on the pronotum 2 



2 — Tarsi moderately elongate, the posterior distinctly shorter than the tibia; in both 

 sexes 3 



Tarsi more elongate, the posterior as long as the tibiae 5 



3 —Eyes rather large and well developed, more than half as long as the head ; body 

 much stouter, dark rufo-testaceous throughout, the vestiture much longer though 

 sparse ; prothorax relatively small, three-fifths wider than long, parallel and 

 nearly straight at the sides, the teeth very large, subacute and conspicuous ; elytra 

 large, parallel, evenly rounded behind, three-fifths longer than wide, fully a 

 fourth wider than the prothorax and much more than three times as long, the 

 punctures coarse and not very close-set ( $? ). Length 2.6 mm.; width 1. 1 mm. 

 California minax, sp. now 



Eyes smaller but not more prominent, scarcely half as long as the head ; body darker 

 in coloration, the pubescence much shorter 4 



4 — Body oblong-oval, moderately slender, shining, blackish -piceous in color, the legs 

 paler ; pubescence moderately short, coarse, somewhat abundant and distinct ; 

 prothorax rather strongly transverse, about two-thirds wider than long, strongly, 

 densely punctate, parallel and broadly arcuate at the sides, the teeth well devel- 

 oped but less so than in minax; elytra elongate, two-thirds longer than wide, 

 only slightly wider than the prothorax and more than three times as long, quite 

 coarsely, but not very densely, punctate {$ )■ The female is larger but virtually 

 similar in every way, the prothorax not relatively much smaller. Length 1.9- 

 2.5 mm.; width 0.75-0.9 mm. California (Siskiyou and Sta. Cruz Cos.). 



lictor, sp. nov. 



Body nearly similar in form and coloration but less elongate, the prothorax large, 

 much less transverse, barely one-half wider than long, the vestiture much shorter 

 and inconspicuous, the sides parallel and evenly arcuate, the teeth pronounced ; 

 elytra shorter, three-fifths longer than wide, slightly wider than the prothorax and 

 two and three-fourths times as long, the punctures decidedly less coarse and 

 rather more close-set, the pubescence much shorter, even, decumbent and not 

 very close ( $ ). Length 2.0 mm.; width o.S mm. California (Lake Tahoe). 



monta mis, sp. nov. 



5 — Body narrowly oval, rather depressed, shining, pale rufo- ferruginous throughout, 

 almost similar in the sexes, the female larger ; eyes rather small, not quite half as 

 long as the head, the antennae moderate as usual ; prothorax parallel and broadly 

 arcuate at the sides, but little more than one-half wider than long, the teeth 

 strongly developed and serriform ; elytra three-fifths to two-thirds longer than 

 wide, relatively a little broader in the female, rather coarsely, but not very 

 densely, punctate, rather arcuate at the sides and narrowly rounded behind, 

 slightly {$ ) or distinctly ( O ) wider than the prothorax and three times as 

 long, — or slightly more in the female, the pubescence short, even, rather sparse 

 and suberect. Length 1.75-2.3111111.; width 0.7-0.85 mm. California (south- 

 ern) — Mr. Fall tarsal is, sp. nov. 



The species are sufficiently numerous and individually abundant on 

 the Pacific coast, to which region the genus appears to be confined. 

 I place here provisionally the Sitkan CryptopJiagus 8-dcntatus of
