40 Mr. F. P. Pascoe on new Neotropical Cure alio nidce. 



Black, loosely covered with a light-brown indumentum, 

 the sides of the prothorax and eljtra covered with bright 

 silvery green overlapping scales, and everywhere, especially 

 the legs, furnished with very minute scattered setulee ; ros- 

 trum curved, a deep groove from the middle to between the 

 eyes ; antennge slender ; scape passing behind the eye ; 

 funicle elongate, second joint more than twice the length of 

 the first, the fourth shorter than the third or fifth ; club ellip- 

 tic ; prothorax transverse, rounded at the sides, subgranulate ; 

 scutellum cordate ; elytra seriate-punctate, each rounded at 

 the apex, green stripe broad, irregularly indented, at one 

 point behind the middle continued to the outer margin ; body 

 beneath with silvery green scales on each side and on the coxaj. 



In coloration this species resembles to a certain extent N. 

 staurojiterus [Leptocerus stauropterus, Germ.) ; but, inter alia, 

 the stripe on the elytra is continuous, not interrupted so as to 

 give the black central portion the figure of a cross as in the 

 latter. 



Naupactus serenus. 



JV. niger, squamulis cupreis dense tectus, elytris singulatim vittis 

 duabus metallice viridibus oruatis. Long. 6 Ihi. 



Hab. Parana. 



Oblong-obovate, black, covered with cupreous scales, each 

 elytron with narrow metallic green stripes ; rostrum slightly 

 concave above ; antennge ferruginous ; scape scarcely extend- 

 ing behind the eye ; funicle with all the joints elongate, the 

 second three times as long as the first; club slender, not 

 longer than the two preceding joints together ; prothorax 

 transverse, rounded at the sides, not canaliculate ; scutellum 

 round, covered with golden-green scales ; elytra moderately 

 convex, obliquely truncate at the shoulders, the apex nar- 

 rowly rounded, irregularly seriate-punctate, the punctures 

 minute, outer green stripe nearly the length of the elytron, 

 the inner shorter ; body beneath covered with silvery green 

 scales ; fore legs moderately robust. 



This species appears to have N. decorus (Fab.) for its 

 nearest ally; but the latter has a rugose prothorax and is 

 differently coloured. 



The males in this genus have the elytra much narrower 

 tlian the females, and the prothorax often considerably larger 

 or even globose. 



Naupactus imhutus. 



N. nitide fuscus, squamulis minutis sparse indutus ; elytris vittis 

 duabus inlerruptis marginibusque flavidis. Long. 8 lin.
