This genus comes very close to Amaurus, Burm. (Platydius, 
Westw. Zool. Journ.; Megymenum, Guér. ; Corydius, De Haan,) 
in all its more essential characters, but differs entirely in the form 
of the head and thorax, and in the antennz not being dilated as 
in this genus. Unfortunately the locality of the only known indi- 
vidual of the genus is unknown.

EprropEera,* Westw. 
Genus novum Lnicocephalo Westw. affine. Caput parvum, 
quasi bipartitum, colloque brevi postice instructum. Nasus 
brevis, porrectus, apice rotundato; parte postica subglobosa 
antice et postice constricta, ocellos duos gerente. Antenne 
capite dimidio longiores, graciles, 4-articulatee ; articulo 2ndo 
longiori, ultimo elongato, ovali, vix precedenti tenuiori. Pro- 
muscts fere capitis longitudine libera, 3-articulata, articulo in- 
termedio multo longiori. Prothorax latissimus, angulis anticis 
lateralibus porrectis, lateribus inflato-rotundatis, pone medium 
constrictum, margineque postico bituberculato. Scutellum 
parvum, triangulare. Hemelytra abdomen fere tegentia corio 
parvo, membrana apicale maxima, area magna media venis 4 
ad margines emissis, Abdomen oblongum, valde deplanatum 
parallelum, apice rotundato. Pedes breves, satis crassi ; femo- 
ribus crassis, subtus serratis. 
This genus is one of those small forms amongst the Reduviide 
which possess the appearance of the Aradi, and have the antennz 
not attenuated at the tips. The rostrum is however free, and 
the veining of the hemelytral membrane very similar to that 
of Enicocephalus and Holoptilus. Another group allied to these 
* At the suggestion of Mr. A. White (to whom this paper was referred by the 
Publication Committee) the name of Physoderes given to this genus, as printed in 
the Journal of Proceedings, has been altered, as being too near to Physodera, a 
subgenus separated from Lebia.—J. O. W.
