BUTTERNUT. LEAVES. 



its form and spots to tlie Erazilian Enchophyllum ensatum* to be 

 generically separated from that species. Indeed the distinction 

 between the two genera is much too slight and vague, in my view, 

 to justify their division. In some of the species which authors 

 place under Enchenopa the thorax appears to be as distinctly 

 compressed, thin and foliacious as it is in some of those arranged 

 under Enchophyllum. The cells and veins of the wings are also the 

 same in all these insects. It is therefore on good grounds that 

 M. Fairmaire suppresses Dr. Burmeister's section foliaceo-ensatcBj 

 the equivalent of Enchophyllum and includes all these insects 

 under the one section, ensatce. At the same time we view this 

 group as too widely different and conspicuously marked by the 

 horn-like protuberance of the thorax, to be retained under the 

 genus Memhracis. We would accordingly drop the name En- 

 chophyllum^ and include all these insects in the one genus Enche- 

 nopa^ a term meaning sword-faced or sword-fronted, and which is 

 therefore appropriate for all the species of this group. 



191. Butternut tree-hopper, Ophiderma mera, Say. (Ilomoptera. Mem- 

 bracidae.) 



A greenish gray tree-hopper shaped like a half cone, with its 

 apex bright chestnut-red and behind its middle a black band 

 which is sometimes interrupted on the summit of the back, and 

 with a blackish spot on the tips of the hyaline wing-covers. 

 Length 0.36. 



I have only met with this insect in a few instances, always 

 upon the butternut. I could find no place for this species among 

 the genera characterised by Amyot and Serville, and therefore 

 l>r(»posed a new genus named Caranota in my catalogue of Ilomop- 

 tera in the State Cabinet of Natural History. Tliis genus aj^pcars 

 to be the same witli that named Ophidcrma by M. Fairmaire a 

 few years before. The single species, salamandra^ given as the 

 type of this genus, is credited to the stiite of Xew-York, and ac- 



• Upwards of a dozen indivi(Jtials of th's insect have fallen under my observation, all of 

 which concurred in fhowing lluit it is the male box which is descrihoil by Fubricius, whilst 

 the females have been dc cribod by M. Initiiiuirn as a distinct ppccies und'T the name 

 quiKqucmnculnta . A variety of the female occurs, which I name intermedia, in which 

 ihe anterior spot upon the hook is merely a fiiint cloud eli^^htly paler Lban the ground^ 

 whiUt the middle fron'al »pot is bright uran;;e, or uFiial in this sex.
