Mr. J. S. Baly on new Genera and Species of Gallerucidse. 409 



marginibusque anguste flavis ; pedibus nigris, femoribus basi et 



infra sordide flavis. 

 Mas. CEdeagus basi incrassatus, curvatus, parallelus, ad apicem acute 



angulatus, apicc producto, truncato, recurvato. 

 Foem. Abdominis segmentum anale apice obtuse angulatum, sat 



profunde incisum. 



Long. 4g-5 lin. 



Hab. Banks of the Napo, Ecuador. 



Thorax rather less broadly dilated than in D. cinctipenne, its 

 upper surface much less deeply excavated. Elytra pale, almost 

 sea-green, fusco-sericeous, broader and more depressed than in 

 D. cinctipenne ; more nearly approaching in habit to D. colum- 

 bicum, but from that species the smaller size and differently 

 formed thorax will separate it ; three upper joints of antennas 

 yellowish white, the remainder more or less fulvous beneath. 



I obtained three specimens of this pretty species (two $ and 

 one $ ) from the late Mr. H. Cuming, who received them from 

 one of his correspondents in Ecuador. 



Dircema sordidum. 



D. elongatum, parallelum, convexum, fulvo-fuscum aut sordide ful- 

 vum, nitiduin, femoribus dorso, tibiis tarsisque pieeis, vertice 

 fronteque viridi-nigris ; antennis nigro-piceis, basi externa et apice 

 fulvis ; thorace longitudine triplo latiore, lateribus ante medium 

 late explanatis ; disco rugoso, profunde transversim excavato, 

 pone sulcum elevato, pube adpressa dense obsito, nigro, vitta lata 

 centrali et margine apicali dilatato flavis ; elytris rude granulosis, 

 obscure metallico-viridibus, pube adpressa fusca dense vestitis, 

 sutura margineque obsolete flavo-marginatis. 



Foem. Abdominis segmentum anale apice obtuse angulatum, scmi- 

 circulariter incisum. 



Long. 4 lin. 



Hab. Ega and Nauta, Upper Amazons. 



Very similar in form, both of thorax and elytra, to D. cincti- 

 penne; easily distinguished from that insect by the coarser and 

 closer pubescence of the upper surface, and by the extremely 

 narrow and almost obsolete fulvous margination of the elytra ; 

 the notch on the apex of the anal segment of the abdomen in the 

 $ is semicircular, instead of linear, as in D. cinctipenne. 



I know two specimens of the species, both $ . The specimen 

 from Ega has the scutelluni dark fuscous. 



Dircema modestinn. 



D. elongatum, parallelum, convexum, dorso subdeplanatum, flavum, 

 nitidum, verticis macula bilobata antennisque nigris, bis apice 

 flavo-albis ; thorace longitudine fere triplo latiore, lateribus ante
