(Sp. Ha.) Oeplialoleia dimidiaMcornis. 



Elongata, parallela, subdepressa, rufo-fulva, nitida, an- 

 tennis extrorsum nigris ; thorace longitudine paullo la- 

 tiorij lateribus parallelis^ disco remote, ad latera subre- 

 mote punctato ; elytris thorace latioribus, parallelis, apice 

 conjunctim rotundatis, tenuiter punctato-striatis, striis ad 

 apicem fere deletis. 



Mas : abdominis segment© anali late sed leviter emar- 

 ginato, medio sinuato. 



Fern. : abdominis segmento anali late sed leviter emar- 

 ginato. 



Long. 2 lin. 



Hah. — Peru. 



Antennae half the length of the body, five upper joints 

 black, third joint distinctly longer than the second. 

 Thorax about a fifth part broader than long, sides nar- 

 rowly but strongly reflexed, straight and parallel, the 

 extreme apex quickly rounded and converging, the an- 

 terior angles obtuse ; above transversely convex, distinctly 

 punctured, the puncturing distant on the disc, rather 

 more crowded at the sides. Elytra parallel, conjointly 

 rounded at the apex, finely but distinctly punctate-striate, 

 the punctures nearly obsolete towards the apex of the 

 elytra. 



The smaller size and narrower form will distinguish 

 this species from its allies C. nigricornis and proxima. 



(Sp. lib.) Cephaloleia nigriecps. 



Elongata, subparallela, subdepressa, rufo-fulva, nitida, 

 capite nigro ; thorace longitudine vix latiori, ad latera 

 subcrebre, disco remote punctato ; elytris parallelis, apice 

 rotundatis, tenuiter punctato-striatis.

Long. 24 lin. 



Hah. — Peru. 



Head and antennae black, the latter moderately robust, 

 nearly half the length of the body, the third joint very 

 slightly longer than the second. Thorax rather broader 

 than long, sides slightly diverging forwards, straight 

 from the base nearly to the apex, thence quickly rounded
