MEMBRA CIDJE. 
For reference elsewhere the following insects may be noted : 
Hemiptycha punctata = Hemiptera cerous, Germ. Fairm. l.c. p. 313. 
Hemiptycha compressicornis, Fairm. l.c. PI. YI. lig. 18, p. 313. 
Hemiptycha expansicornis, Fairm. l.c. p. 317. Brazil. 
Genus: EUALTHE. 
Stal. Ofv. Yet. Akad. Fork. 24. p. 557. 
As before stated, this genus was separated from Hemiptycha to receive apparently 
only two species which might have better remained where Fairmaire placed them. 
Nevertheless, I place them here for the convenience of reference. 
EUALTHE LAEVIGATA. 
Fairm. (Hemiptycha), laevigata, l.c. p. 318. Stab Eualthe laevigata, l.c. p. 25 (type). Walk. 
Hemiptycha attenuata, l.c. Suppt. Walk. //. longa, l.c. p. 570, Suppt. p. 144. 
Habitat. —Brazil. 
B.M. Collection. 
EUALTHE PUNCTUM. 
Fairm. be. Hemiptycha, PI. VI. fig. 22, p. 318. 
This insect must not be confused with H. punctata, which is much larger and has 
a convex dorsum. 
Size, 14 x 4 mm. 
Ha bit at. —Brazil. 
Eualthe laevigata is represented in the B.M. Collection, but I have not seen 
E. punctum. 
Mr. W. F. Kirby has kindly helped me as to above synonymy of this 
varied section of Hemiptycha. 
NESSORHINUS VULPES, Am. et Serv. 
(Plate XXIX. figs. 5, 5a-5c.) 
Nessorhinus vulpes, Am. et Serv. l.c. p. 542, 437. N. vulpes, Fairm. l.c. p. 296, PI. XII. fig. 11. 
V. vulpes, Walk. l.c. p. 542. 
Pronotum with a porrected carinated process in the form of a snout, or the beak of 
a duck ; dorsal ridge sinuous, rising between the shoulders and then swelling into a 
fiat hump-like process which is covered with a white pilose coat; the ridge is carried 
as a sharp carina to the posterior apex ; the pronotum is free from the scutellum, 
which, however, is not easily seen ; tegmina, light drab colour; membrane 
hyaline, fumose with brown neurations; apical cells four, oblong discoidals two ;
