pression between the antennjp and two oblique ridges, broadly emargi- 

 uate at apex. Thorax strongly convex, impunctate, apical and basal 

 margin black; scutellar fovea^- nearly obsolete; basal lobe short, trun- 

 cate; margin serrate at the sides of the base; posterior angles acute. 

 Scutelluin much inclined, black, incised in front. Elytra convex, 

 slightly gibbous at apex of scutellum, with regular rows of punctures, 

 confused at apex; base, suture, and apical half of side, margined with 

 black; humeral callus not prominent; epipleural lobe broadly rounded. 

 Pygidium and ventral surface black, feebly shining, punctate, si)arsely 

 hairy. Prosternum concave, broadly emarginate at apex; oral lobe 

 very large, vertical, semicircular at apex; mesosternum transverse, 

 flat; metasternum at apex and last ventral segment largely excavate

PSEUDOMACETES, new genus. 



(Group I'siudocoJaspiies, Chapnis.) 



Head rounded; epistoma and labrum emarginate; eyes rounded, 

 entire, partly covered by the produced anterior angles of prothorax; 

 antenna? as long as half the body, first joint oblong, intlated, second 

 obcouical, shorter than third, third to sixth elongate, compressed, 

 nearly glabrous, very finely punctate, seventh to eleventh incrassate, 

 longer than broad, pubescent and coarsely punctate. Prothorax much 

 narrower than elytra, sides acutely margined, strongly convergent 

 from the base. Scutellum pentagonal. Elytra irregularly punctate 

 with prominent humeral umbone. Prosternum large, transverse, flat. 

 Femora edentate, incrassate at middle, the anterior and posterior pair 

 distinctly larger than the middle pair. Tibije without emargination, 

 gradually enlarged toward apex, deeply striate; tarsi not broader 

 than apex of tibia', joints one and two subequal, claws cleft. 



PSEUDOMACETES ^NEUS, new species. 



Dark leneocupreous, including antenn;e and legs, sparsely covered 

 with a fine white appressed pubescence. Head and thorax finely 

 punctate. Elytra gradually narrowed from the humeri, conjointly 

 rounded at apex, coarsely punctate, subseriately on the posterior tliird. 



Types.— ^o. 32, U.S.N.M. Two examples. Tana Piver. Length, C 

 to 8 mm. 



CHRYSOMELA SCUTELLARIS, new species. 



Ovate, moderately convex, above coarsely punctate and very finely 

 reticulate, feebly shining. Head red, with a dark cloud on vertex; 

 mouth parts black; antenna' black, gradually and strongly clavate. 

 Thorax regularly convex, much narrower than elytra, black with sides 

 red, more broadly in front; base strongly rounded; apex squarely 

 truncate; lateral impressions almost entirely eftaced, indicated only by
