ADRIMUS CREPERUS, 0. sp. 
A. viridescenti quoque proxime affinis ; differt tantum colore minus: 
piceo, magis eneo, elytrorum suturd marginibusque vie rufescentibus, 
. . . | 
thorace postice vix angustato, versus angulos posticos haud explanato,, 
angustissime pallido marginato. Long. 3% lin. 8.

Genus DIPLOHARPUDS. 
Chaudoir, Bull. Moscou, 1852, ii, p. 894. 
A remarkable genus of Anchomenine, peculiar to Tropical America, 
and distinguished by the long narrow mandibles and other parts of the 
mouth,—the long exserted maxille projecting even beyond the mandi- 
bles. The pubescence of the antenne commences at the third or even | 
the second joint, but it is not dense on these joints, and it is doubtful 
if the fine pubescence proper can be said to commence before the 4th. 
DIPLOHARPUS EBENINUS, N. sp. : 
D. levissimo (Chaud.) proxime affinis, at minor, gracilior, elytrorum — 
strid 2°44 profundius impressd ; nigerrimus, elytris leviter iridescentibus, 
oris partibus, antennis, trochanteribus, tibiis intus tarsisque rufo-testaceis : 
capite thoraceque ut in D. levissimo impunctatis ; elytris convewxis, postice 
gradatim dilatatis, prope apicem abrupte angustatis, supra levissimis, 
striis duabus punctatis prope suturam distinctis, ad basin obliteratis, 
prima solum apicem attingenti ; femoribus extus picets : abdomine 
rufescenti. Long. 43 lin. Lat. elytr. 13 lin. 8. 
The dimensions given by Baron Chaudoir for his South Brazilian 
species, D. levissimus, are, “Long. 5 lin., lat. elytr. 2 lin.,” which agree 
with my specimen. JD. ebeninus is smaller and more slender; the ¢ 
differing from ¢ levissimus in the elytra being narrower at the base 
and dilated towards the apex.

DIPLOHARPUS RUBRIPES, 2. sp. 
D. levissimo similis, at multo minor, nee non gracilior, elytris ovato- 
cordatis, baseos medio paulo emarginato, humeris distinctioribus ; niger, 
nitidus, oris partibus, antennis, pedibusque rufis ; abdomine elytrorumque 
margine deflexo piceo-rufis ; corpore supra levissimo, elytris striis duabus 
punctatis, suturali solwm distinctd, impressis.
