CORYMBITES. 



Corymbites trtundulatus, Lee. Trans. Am. Phil. Soc. x. 457 ; 

 Candfeze, Elat. iv. 145. 



Elater triundulatus, Randall, Bost. Journ. 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. 



Corymbites fraternus. 



Obscure aeneus, nitidus, pube cinerea longiuscula vestitus ; prothorace 

 latitudine Ipngiore, fortiter sat dense punctato, angulis posticis 

 elongatis, obliquis at vix divaricatis, broviter carinatis ; elj-tris 

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

 nis pedibusqiie piceis vol piceo-ferrugineis, illis articulo 3"'° sc- 

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



Long. 15-17 millim. 



One pair. In the male the prothorax is gradually narrowed 

 and feeblj 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 dificrs chiefly by the hind angles of the prothorax, 

 which are not so narrow and are scarcely divaricated. 



ASCLERA. 

 Asclera nigra. 



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

 postice angustato, latitudine vix longiore, dense punctulato, apice 

 subsinuato, basi late rotundato, apico subconstricto, latcribus 

 medio rotundatis, postice late siuuatis, disco subtilitor punctulato, 

 foTcis tribus latis impresso, ante medium subcarinato ; olytris 

 confcrtissime punctatis, lineis utrinque tribus angustis elevatis. 



Long. 9 millim. 



One specimen. Eesembles somewhat the European A. 

 ccernlea, but diifers 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.
