MEMBRA CIDAE. 35 
The front is truncated and broader than the rest. Legs small; tarsi weak; eyes 
minute. 
Size, 12 x 8 mm. 
Drawn from the larva of M. continua (so labelled) in the Westwood collection at 
Oxford, now incorporated in the Hope collection. 
Canon Fowler notes that the larvae of this genus are very curious, being much of 
the same shape as the perfect insect, but formed of separate upright narrow plates of 
different heights. Vide B.C.A. 
He figures six perfect insects of the genus Membracis. taking M.foliata of Fab. as 
the type. 
MEMBRACIS MEXICANA. 
(Plate II. figs. 5 and C>.) 
Membracis mexicana, Guer. Ic. Reg. Anim. Membracis mexicana, Fairm. Ann. Ent. p. 248. 
Membracis stolida, Fairm. Ann. Ent. p. 248. Membracis sexmaculata, Walk. Homop. supp. p. 59. 
Membracis mexicana , Fowler, B.C.A., Tab. i. figs. 4, 5. 
Pronotum slightly raised; colour fine, or sometimes, sordid yellow, with brown 
spots above the eyes, one behind each shoulder, and two or more spots on the dorsum, 
also a large one touching both the superior and the inferior borders {see fig. 6); 
tegmina and legs blackish. 
This is a species abundant throughout all Central America. It appears very 
variable as to size and marking, ranging from 6 to 10 mm. 
Fowler considers that M. stolida represents the larger forms and sexmaculata the 
smaller. 
Size is probably connected with locality. 
Habitat.— Guatemala, Belize, Honduras, Nicaragua, Costa Rica, Colombia, Panama. 
I figure two varieties. 
In the B.M. catalogue this insect is included in Stal’s sub-division Vhyllotropis. 
MEMBRACIS ARCUATA. 
(Plate II. figs. 7 and 7a.) 
Membracis arcuata, Oliv., Germ. Cicada arcuata, De Geer, t. xxxii. fig. 10. Membracis dorsata 
Fab. S. Rh. ii. 2G. Membracis perispheria, Fairm. plate iv. fig. 15. Membracis arcuata, Fairm. 
plate iv. fig. 25, p. 247. 
Fairmaire simply describes this species as black, often interrupted by a white 
longitudinal fascia. The figure I give well agrees with the outline figure in 
Fairmaire as above cpioted. 
Size, 12 x 7 mm. 
Habitat. —Brazil.
