256 MEMOIRS ON THE COLEOPTERA 



elytral punctures, these being as sparse as in similis but feebler and more 

 diffusedly impressed, black throughout in the type; head and very slender 

 antennae similar; prothorax longer than wide, slightly narrower than the 

 head, otherwise nearly similar; elytra narrower and only about a third 

 wider than the prothorax, two and one-half times as long as wide; ab- 

 domen shining, the fine punctulation not dense, the ashy hairs decumbent; 

 legs slender, shorter, the tarsi extremely slender, much more so than in 

 subargentata. Length (cf ) 5.5 mm.; width 1.3 mm. Washington State. 



In subargentata and similis the prothorax is almost as wide as 

 the head, but in filicornis it is evidently narrower. The following 

 species is widely distinct from any other known species of the genus 

 in its stouter form : 



Parallelina campanifera n. sp. Stout in form, parallel, moderately 

 convex, shining, alutaceous anteriorly, deep black throughout, the pu- 

 bescence everywhere short, not dense, dusky and inconspicuous; head 

 small, very finely, closely punctate, the front very short before the eyes 

 though evident; tempora rapidly oblique and feebly arcuate; antennae 

 (9) slender, filiform, with the outer joints gradually shorter, not two- 

 thirds as long as the body; prothorax much larger than the head, rather 

 longer than wide, strongly convex, rather strongly, closely punctate, with 

 .a narrow impunctate line, the sides gradually and moderately converging 

 and broadly arcuate from base to apex, gradually more strongly so 

 apically, the basal angles everted and very acute; elytra not a third wider 

 than the prothorax, perfectly parallel, two and a third times as long as 

 wide, very broadly obtuse at apex, the apices narrowly subtruncate; 

 punctures as large as those of the prothorax but separated by twice their 

 diameters, fine but asperulate apically; abdomen shining, with minute 

 though ashy vestiture, finely, not densely punctulate, closely so basally, 

 sparsely apically; legs slender, the basal joint of the hind tarsi much longer 

 than the remainder. Length (9) 8.3 mm.; width 2.7 mm. California 

 (Mokelumne Hill, Calaveras Co.), Blaisdell. 



There is no described species with which this can be closely com- 

 pared. The male is probably notably less stout. The head is 

 unusually small, even for the present genus. 



Charisalia n. gen. 



The only species at present known to form part of this genus are 

 americana Hald., and capitata Newm. Charisalia is rather closely 

 allied to the preceding, but there is a notable difference in habitus, 

 and the maxillary palpi are much larger and longer than in Paral- 

 lelina. There is a remarkable difference in the form of the fourth 

 palpal joint pertaining to four slender specimens of capitata from 

 Ontario, and two larger, stouter and more parallel examples from
