110 DESCRIPTIONS OF NEW SPECIES. 



latiores, angulo externo apicali producto acuto. Tarsi subtus breviter 

 pubescentes. 



This genus is established upon Ejritragus puberulus Dej. Cat., 

 and differs from Epitragus by the presternum not being produced 

 behind and received by the mesosternum. The antennae are 

 more slender, and the genae are also less prominent, being quite 

 rounded at tip. The prothorax is but feebly emarginate in front, 

 and the anterior angles are not at all prominent. It seems to be 

 more nearly related to Himatismus than to the other described 

 genera of this tribe. 



311. S. pilberulus. Rufo-picens nitidus, breviter parce pubescens, 

 capite thoraceque punctatis, boc latitudine sesqui breviore, antrorsum 

 angustato, lateribus rotundatis baud rnarginatis, apice fere truncato, 

 basi bisinuata, angulis anticis rotundatis, posticis obtusis ; elytris sub- 

 tilius punctatis, obsolete striatis, tborace paulo latioribus et plus qua- 

 druplo longioribus. Long. *34. 



One specimen, collected in Georgia, by Mr. John Abbott. 

 There is a slight metallic gloss visible upon the elytra, which 

 may sometimes become more obvious. 



PELEC1PHORIS Solier. 



318. P. COJinivens. Niger opacus, pube brevi sordida parce vestitus, 

 capite tboraceque confertim fortiter punctatis, boc latitudine longiore, 

 antice posticeque sequaliter modice angustato, lateribus late rotundatis, 

 postice subcrenatis, margine reflexo, angulis anticis productis acutis, 

 posticis acutis divergentibus, basi bisinuata, disco late et profunde 

 canaliculate ; elytris ovatis, postice oblique attenuatis, tborace sesqui 

 latioribus, subtilius punctatis margine laterali costaque dorsali acute 

 elevatis ad bumeros conniventibus. Long. '40. 



One specimen, from Lower California, in the collection of Mr. 

 Ulke. Related to P. bifurcus, but much smaller, with the hind 

 angles of the thorax more prominent, the dorsal channel deeper, 

 and the elytral costa diverging from the margin at the humerus, 

 instead of just in front of the middle. 



The dorsal costa terminates near the suture, about one-third 

 from the tip ; the marginal costa extends to within one-sixth of 

 the tip. The antennae and legs are very long in the specimen, 

 which is a male. As in P. bifurcus, the anterior tibiae are trun- 

 cate at tip, with the outer angle not prolonged.
