_ ALEOCHARA. 147 
2. Aleochara serrata. 
Nigra, elytris rufis, ad angulum exteriorem nigricantibus, antennis fuscis, basi, palpis pedibusque testaceis, 
ano rufescente, abdomine fortiter punctato; antennis crassis, fusiformibus. 
Long. 8 millim. 
Hab. Mexico, Tehuantepec (Sumichrast, coll. Sallé)—Sourn America, Bahia. 
Antenne stout, the two or three basal joints yellow, the middle joints only very 
slightly thicker than the penultimate, these latter being rather strongly transverse. 
Head coarsely punctate. Thorax coarsely punctate, with a griseous pubescence, base 
and sides much rounded. Elytra a little shorter than the thorax, rather coarsely and 
closely punctate. Hind body coarsely and rather closely punctate, with the exception 
of the basal segments, which are but little punctate. 
In the male the extremity of the seventh dorsal plate of the hind body is truncate, 
scarcely perceptibly emarginate in the middle, and bears about twelve distinct, distant, 
rather coarse, short teeth. 
This insect is extremely similar to the well-known European A. fuscipes ; but the legs, 
palpi, and base of the antenne are of a clear red colour, and the apex of the hind body is 
conspicuously rufescent ; the antenne are rather more slender, and the male characters 
different. I have described the species from a single badly preserved individual; but a 
series from Bahia apparently agree, except in having the antenne rather stouter. 
3. Aleochara pauper. 
Minus lata, anterius et posterius parum attenuata, nigra; elytris brunneo-testaceis, ad latera infuscatis, 
antennarum basi pedibusque sordide rufis; abdomine fortiter punctato; antennis brevibus crassis, 
subfusiformibus. 
Long. 6 millim. 
Hab. Muxico, Jalapa (Hoge). 
Antenne short and very stout, the three or four basal joints reddish, joints four to 
ten strongly transverse, the first of them rather smaller than the others, which differ 
but little from one another. Thorax rather coarsely punctate, shining. Llytra short, 
scarcely so long as the thorax. Hind body rather coarsely and closely punctate, with 
the exception of the basal segments. 
Although I have seen only a single specimen, it is clear this represents a species 
distinct from A. serrata, the form being more parallel, the colour of the elytra different, 
the extremity of the hind body less rufescent, and the antenne shorter and stouter. 
The specimen is a male, and has the hind margin of the seventh ventral segment 
serrate, much in the same manner as A. serrata.
