COEYMBITES. 



Corymhites triundulatus, Lee. Trans. Am. Phil. Soc. x. 457 ; 

 Cand^ze, Elat. iv. 145. 



Mater tnundulatus, Randall, Bost. Joum, Nat. Hist. ii. 12. 



A female specimen, much larger (11 millims. long) than 

 those from Lake Superior and Maine, but -which does not 

 differ from them in form and sculpture. The middle angu- 

 lated dark band is equidistant between the other two, instead 

 of being nearer to the hinder one as in our eastern specimens ; 

 I do not think that this is a sufficient character to establish 

 it as a distinct species, although the prothorax seems to be a 

 little broader. 



X Corymhites fraternus. 



Obscure seneus, nitidus, pube cinerea longiuscula vestitus ; prothorace 

 latitudine longiore, fortiter sat dense punctate, angulis postieis 

 elongatis, obliquis at vix divaricatis, breviter carinatis ; elytris 

 striis angustis vix punctatis, interstitiis planis, punctatis ; anten- 

 nis pedibusque piceis vel piceo-ferrugineis, illis articulo 3''° se- 

 cundo paulo longiore at vix latiore, conjunctis 4'° baud longioribus. 



Long. 15-17 minim. 



One pair. In the male the prothorax is gradually narrowed 

 and feebly rounded on the sides from the base to the apex ; in 

 the female the body is more robust, the sides of the prothorax 

 are nearly parallel behind, and more strongly rounded before 

 the middle. 



This species is very closely allied to the Alaskan C. angus- 

 ticollis, but differs chiefly by the hind angles of the prothorax, 

 which are not so narrow and are scarcely divaricated. 



ASCLEEA. 

 xAsclera nigra. 



Cyaneo-nigra, opaca, brevissime pubescens ; protborace obovato, 

 postice angustato, latitudine vix longiore, dense puuctulato, apice 

 subsinuato, basi late rotundato, apice eubconstricto, lateribus 

 medio rotundatis, postice late sinuatis, disco subtiliter punctulato, 

 foveis tribus latis impresso, ante medium subcarinato ; elytris 

 confertissime punctatis, lineis utrinque tribus angustis elevatis. 



Long, 9 millim. 



One specimen. Resembles somewhat the European A. 

 ccerulea^ but differs by the much deeper excavations of the pro- 

 thorax : it agrees in form and sculpture with the Californian 

 A. excavata, Lee. ; but the thorax in that species is rufous, 

 more elongate, and much less punctured than in the present 

 one.
