368 Mr. J. S. Baly on New Qenera 



punctato, lateribus a basi paullo ultra medium rectis', 

 parallelis ; elytris thorace paullo latioribus, parallelis, 

 apice rotundatis, tenuiter punctato-striatis, striis apicem 

 versus leviter sulcatis, interspatiis ad latera leviter con- 

 vexiusculis, punctis ad apicem fere deletis. 



Fern.: abdominis segmento anali apice bisinuato; 

 pygidii apice obtuse angulato. 



Long. 2^ lin. 



Sab. — Upper Amazons. 



AntennEe rather longer than the head and thorax, 

 moderately robust, seven upper joints black, the apices 

 of the third and fourth also remotely edged with the 

 same colour; second joint equal in length to the third. 

 Thorax about one-fifth broader than long, sides straight 

 and parallel from their base to a short distance beyond 

 the middle, thence rounded and converging to the apex ; 

 upper surface transversely convex, sides distinctly but 

 narrowly reflexed, disc remotely, sides and base more 

 closely impressed with distinct round punctures. Elytra 

 broader than the thorax, parallel, finely but distinctly 

 punctate-striate, the striae on the sides and hinder half 

 of the elytra slightly sulcate. 



C. 8allei is the only previously described species with 

 which the present insect can be confounded ; it may be 

 however at once known by the shorter third joint of 

 the antennee, the somewhat narrow and more closely 

 punctured thorax, and by the more finely punctured 

 elytra ; in C. Sallei the elytra are much more strongly 

 punctured, the punctures being of equal size, and equally 

 impressed over the whole surface of the elytra. 



(Sp. 9a.) Cephaloleia laticollis. 



Oblonga, parallela, depressa, rufo-fulva, nitida; an- 

 tennis apice, oculisque nigris, antennarum articulo se- 

 cundo distincte tertio breviori ; thorace elytris sequilato, 

 lateribus rectis, angulis anticis fere rectis, acutis, disco 

 remote, lateribus subcrebre punctate; elytris tenuiter 

 punctato-striatis, interspatiis tenuissime punctatis. 



Mas. : abdominis segmento anali medio modice rotun- 

 dato-emarginato . 



Fem. : abdominis segmento anali apice leviter bisinuato. 



Long. 2 lin.
