According to the West-Indian specimens named by M. Grouvelle (Trans. Ent. Soc. 
Lond. 1898, p. 404), this insect is extremely similar to Silvanophleus gundlachi, and I 
expect will prove to belong to that genus. It has an impunctate head and thorax, 
and the latter has straight sides converging behind. Two of our specimens of 
S. gundlachi from Zapote approach rather nearly to this West-Indian series, but do 
not agree satisfactorily. | 
LATHROPUS. 
Lathropus, Erichson, Naturg. Ins. Deutschl. iii. p. 327 (1845). 
This genus includes only three or four species of rare, very minute beetles. Its 
position appears to me doubtful; but 1 am not able to throw any light on it, or even 
to express an opinion as to whether the New World insects are really congeneric with 
the European species for which the genus was established.

M. Grouvelle at first thought the examples in M. Sallé’s collection that I have 
referred to L. pictus were this species, but he informs me he does not now consider this 
to be the case. 
RHABDOPHLCKUS, gen. nov. 
Coxee posteriores tantum parum distantes, a processu acuminato separate. 
This genus is well distinguished from Lemophiewus by the small size of the 
abdominal process projecting between the posterior coxe. ‘The epipleure are very 
definite. All the species possess very distinctly costate wing-cases. The head is small, 
and quite destitute of peculiar developments in the male. ‘The lower lip and palpi 
are very small. The anterior acetabula are not closed. 
1. Rhabdophleus concolor, sp. n. 
Parvus, depressus, ferrugineus, dense subtilissime punctatus et pubescens, subopacus ; prothorace brevi, 
margine laterali crenulato, intra marginem unicostato ; elytris minus alte costatis. 
Long. vix 2 millim. 
Hab. Mexico, Tehuantepec (Hoge); Guatemata, Zapote (Champion).
