On some new Brazilian Hemiptera. 
Flypocaccus asper, sp. n. 
Ovalis, convexus, fere niger, parum nitidus, supra undique dense 
punctatus; fronte stria integra antice carinata; pronoto lateribus 
rugoso-punctato ; elytris striis 1-4 fere integris, suturali parte 
geminata; prosterno angusto, striis approximatis. 
L, 24-3 mill. 
Oval, convex, black, densely punctured above, and more 
coarsely and conspicuously punctured on the mesosternum ; 
the head rugosely punctured, frontal stria complete and carini- 
form over the eyes and anteriorly ; the thorax punctured like 
the head, interstices rugose except on the disk, marginal stria 
complete but extremely fine behind the head, punctured like 
the head, with interstices generally longitudinally rugose, 
striee, outer humeral complete, inner short and median, 1-4 
almost complete but apically somewhat obliterated by the 
punctuation, sutural complete, geminate on the dorsum, and 
joining the fourth at the base, it also continues along the 
apical rim, which is very narrowly smooth; the pygidia are 
densely punctured; the prosternum, the keel is very narrow 
and the strize are formed like those figured for H. 4-striatus, 
Hoffm. (Ann. & Mag. Nat. Hist. ser. 7, vol. iv. p. 2, 1899). 
The mesosternum is widely sinuous anteriorly, stria complete, 
surface punctate; the metasternum has a median longitu- 
dinal sulcus, deepest posteriorly, and the punctures are large 
along the hinder border; the anterior tibiz are somewhat 
dilated and 6-7-dentate. 
Superficially this species resembles the figure given by 
Marseul for Saprinus delta, but the frontal stria is carinate 
and straight anteriorly, and beneath the mesosternal stria is 
complete.

Aphide. 
Genus CERATOVACUNA, Zehntner, 1897. 
It will be necessary to revise the characters of this genus, 
as published by Dr. Leo Zehntner in 1897, from Java, in 
order to include the Brazilian species.
