302 Mr. J. S. Baly's descriptions of new genera 



obtuse; upper surface granulosa and rather distantly- 

 punctured. Elytra broader than the thorax, ovate; above 

 convex, strongly and regularly punctate-striate ; inter- 

 spaces slightly convex, more strongly so on the outer disk 

 and towards the apex, nitidous, here and there faintly 

 wrinkled, the rugosities being visible only when viewed 

 under a strong lens ; inflexed limb smooth and shining, 

 impressed along its inner edge with a single row of punc- 

 tures. Nearly allied to C. Mexicana ; separated from 

 that species by its rather broader form and by the diverging 

 sides of the thorax. 



Chcetocnema gravida. 



Late ovata, valde convexa, cuprea, nitida, pedibiis 

 antennisque obscure fulvis, his extrorsum piceis, femoribus 

 anticis quatuor piceo-tinctis, posticis cupreis ; clypeo crasse 

 punctato; thorace sat fortiter punctato; elytris regulariter 

 punctato-striatis, interspatiis granulosis, planis, externis 

 vix convexiusculis. 



Long. l|lin. Hab. — Mexico; Teapa. 



Vertex distantly punctured ; clypeus trigonate, deeply 

 and closely punctured ; encarpee and carina entirely obso- 

 lete. Thorax twice as broad as long at the base ; sides 

 rounded and converging from base to apex, all the angles 

 acute ; upper surface impressed, but not very closely, v»^ith 

 deep punctures. Scutellum transverse, its apex broadly 

 rounded. Elytra slightly broader at the base than the 

 thorax, attenuated towards the apex, strongly and regu- 

 larly punctate-striate, interspaces finely granulose, plane, 

 those near the outer margin faintly convex. 



ChcBtocnema Sallei. 



Anguste ovata, convexa, cuprea, nitida, supra granu- 

 losa, antennis obscure fulvis, extrorsum piceis; pedibus 

 obscure fulvis, piceo-tinctis, femoribus posticis cupreis ; 

 vertice distincte punctato ; thorace sat fortiter punctato ; 

 elytris regulariter punctato-striatis, interspatiis remote 

 punctatis, externis leviter convexis. 



Long. 1^ lin. Hab. — Mexico. 



Vertex distinctly but not closely punctured; clypeus 

 trigonate, more closely punctured than the vertex; en- 

 carpge and carina obsolete ; antennse slightly thickened 

 towards the apex, rather more than half the length of the
