MEMBRACIDJE. 
61 
HYPSOPRORA COSTATA, n.s. 
(Plate IX. figs. 4, 4a.) 
Sordid-ochreous, tinged with grey, punctured with brown dots ; cephalic horn 
stout, erect, curved backward and blunt at the apex ; dorsum with a truncated, and 
also with a smaller horn, both brown ; a still more minute horn occurs near the 
posterior end ; suprahumerals stout, horizontal when viewed from the front; middle 
legs with tarsi broad, spatulate, and grey ; other legs more slender; tegmina brown, 
with a conspicuous white costal patch, also a small white spot between it and the 
apex. 
Size, 6x4 mm. 
Habitat. —St. Vincent. 
Drawn from a single specimen in the Hope Coll. 
The following species are named by Fairmaire or by Stal, but I have not seen 
them for drawing purposes. Mr. Kirby thinks they may be referred to the present 
genus Hypsoprora. 
Hypsoprora pileata, Fairm. l.c. p. 2GG, Tab. VII. fig. 28, Colombia; Hypsoprora cylindricornis, l.c. 
Stal, p. 277, Bogota; Hypsoprora tuberosa, l.c. Fairm. p. 2GG, Corientes; llypsoprora 
capitata, l.c. Fairm. p. 2G7, Colombia; llypsoprora bifida , l.c. Fairm. p. 267, Cayenne. 
N.B.— H. tuberosa of Stal, l.c. p. 27, of Bogota, does not seem to be P. tuberosa of 
Fairmaire, who puts these two insects into his genus Pterygia. 
Genus: BOLBONOTA. 
(Am. et Serv. l.c. p. 537.) 
Membracis. Germ. Burm.; C'entrotus, Fabr.; Tetraplalys, Walk. l.c. ii. p.510; Bolbonota, Stal.; Fair¬ 
maire, l.c. p. 257 ; Fowler B.C.A. p. 15. 
This genus is in form very unlike all those which have been previously described, 
yet gradations between the comprised species are so gentle, that their connection 
with the Membracidae cannot be well doubted. 
The species consist of small globose insects. When at rest their legs are quite 
concealed under their bodies, but when moving they appear like brown or black 
creeping corrugated seeds. Their dense colours make it difficult to draw them 
satisfactorily, even with the help of a strong reflected light.
