MEMBRA CIDJE. 
necessitates much material for dissection. Dr. Goding notes six genera, of which 
Cyrtolobus and Yanduzea are new tc science. 
Cyrtosia of Fitch has been pre-occupied by the Diptera, and therefore Dr. Goding 
proposes Cyrtolobus in substitution. See Trans. Americ. Entomol. Soc., 1892. 
Smilia of Germar shows three nervures passing out of the corium, and continuous 
near the base, with one or two discoidal areas. 
Genus: CYRTOLOBUS, Godg.

Pronotum slightly compressed, and but little eleva'ed; suprahumerals obtuse or 
none ; front angles not produced; apical area stylate.

Canon Fowler’s figure is, as above, drawn from a specimen identical with that 
named by Dr. Goding, Cyrtosia discoidalis Emmons = Atymna carinata. Its general 
character is so similar to that I figure from our National Collection, that I must 
consider these insects are identical. The suprahumerals, however, are much sup¬ 
pressed. Mr. Kirby thinks that Membracis Van of Say should be a synonym of C. 
discoidalis. Five other species of this genus are described in the Biologia Centrali 
Americana, viz. : 
Cyrtolobus crucifer-—Cyrtosia crucifer , St SI. Fowl. l.c. Tab. VIII. fig. 24, p. 140. Mexico. 
C. virescens, Fowler, l.c. Tab. IX. fig. 1, p. 141. Mexico. 
C. distinguendus, Fowl. p. 141. 
C. vittalipennis, Fowler, p. 142. Mexico. 
C. incequalis, Fowl. l.c. Tab. IX. fig. 2, p. 142. Mexico. 
GIBBOMORPHA PARVULA, n.g. 
(Plate XLI. figs. 9 ? , 9a-9c.) 
Small; pronotum smooth, stout, gibbous, and uniformly convex ; the hinder part 
prolonged into a sharp tapering point, which extends nearly to the tips of the 
tegmina, and is so far free from the abdomen as partially to show the rudimentary 
scutellum below; colour black and shining; legs dusky ferruginous, the hind pair 
hirsute ; tegmina rounded with a broad limbus, and with five apical and three discoidal
