ALEOCHARA. 151 
of Oxypoda. A. oxypodia is distinguished from most of the allies known to me by the 
middle cox being slightly more widely separated. Twenty-three individuals of the 
species have been found ; but of these only two are females, and these unfortunately are 
from different localities and where males were not found; thus the identification of 
the sexes as belonging to one species is still a little doubtful. 
11. Aleochara simulatrix. 
Nigra, subopaca, densius subtiliter punctata et pubescens, antennarum basi pedibusque testaceis; elytris 
brunneis, circa scutellum maculaque magna Ilaterali nigris, thorace brevioribus; abdomine crebrius 
punctato. 
Long. 7 millim.

This species, so far as I can judge from a unique female, is extremely similar to 
A. oxypodia, but has peculiar sexual characters, the dorsal plate of the fifth segment 
of the hind body being prolonged in the middle, with broadly rounded hind margin ; 
the seventh dorsal plate resembles in form that of the male of A. oxypodia; and the 
ventral plate of this latter segment is only very indistinctly emarginate in the middle. 
These characters are analogous to those assigned by Solsky (Hor. Soc. Ross. viii. 
p- 290) to the male of A. teniata, Er.; but I think Solsky probably erred in his 
identification, and that his A. teniata 3 is the female of one, his A. teniata 2 the 
female of another, species. This is the more probable, inasmuch as Solsky records the 
locality of his A. twniata as being Cayenne and Peru. As the locality for Erichson’s 
A. teniata is St. John’s Island in the Antilles, it is very doubtful whether it is conspecific 
with either of the two Solskyan species. 
12. Aleochara funestior. 
Nigerrima, dense subtiliter punctata et pubescens, opaca, pedibus fusco-testaceis, tarsis testaceis; antennis fere 
gracilibus, extrorsum vix incrassatis, articulis penultimis vix transversis. 
Long. 6-7 millim. 
Hab. GUatEMALA, Sinanja in Vera Paz (Champion); Panama, Volcan de Chiriqui 
2000 to 6000 feet (Champion). 
Antenne entirely black, third joint a little longer than the second ; fourth joint not 
greatly smaller than the fifth, this rather longer than broad; tenth not quite so long 
as broad; terminal joint scarcely so long as the two preceding together. Palpi 
black, with the slender terminal joint yellow. Head narrow, rather closely punctate. 
Thorax not strongly transverse, much narrowed towards the front, densely punctate and 
pubescent. Elytra shorter than the thorax, very densely and rather finely punctate. 
Hind body much narrowed behind, closely and rather finely punctate. 
In the male the dorsal plate of the seventh segment of the hind body is truncate, 
scarcely perceptibly emarginate, and furnished at the hind margin with ten or twelve
