front as a well-marked rectangle. The sculpture of the elytra is very fine, the striz 
being extremely fine, and obliterated rather than deepened towards the apex; the 
punctures on the strie are finer and closer to one another than those forming the 
series in P. prosternale. The appearance of the insect is quite that of an ordinary 
Cercyon, the European C. lateralis, Marsh., for example. The species is described 
from a single individual. 
5. Pelosoma cercyonoides. 
Breviter ovale, convexum, piceum, nitidum, elytris nigricantibus; antennis, palpis pedibusque testaceis ; capite 
thoraceque fortiter et crebre punctatis; elytris substriatis, striis sat fortiter punctatis, interstitiis sparsim 
punctatis ; prosterno in medio subtiliter carinato.

The head and thorax are rather closely and deeply though not very coarsely punctate, 
the punctuation of the latter not, however, quite so close as that on the head; the stricz 
of the elytra, though not deep, are very distinct, and are a little deepened behind; the 
interstices are very shining, and rather sparingly and finely punctate. The prosternal 
carina, though: but little elevated, is very definite, and forms a very minute prominent 
angle in front. The basal portion of the mentum is coarsely punctate, as is also the 
central piece of the mesosternum. 
The species is described from a single individual. Although very similar to P. sud- 
carinatum, it is very readily distinguished by the more punctate surface and the less 
obsolete prosternal carina; it is also rather less rotund in outline. 
6. Pelosoma subcarinatum. 
Rotundato-ovale, convexum, supra nigricans, anterius rufescens, nitidum, subtus rufo-testaceum; antennis, 
palpis pedibusque testaceis, illarum clava subinfuscata; capite thoraceque sparsim subtiliter punctatis ; 
elytris anterius subtiliter seriatim punctatis, ad apicem leviter striatis, interstitiis sparsim punctatis ; 
prosterno in medio obsolete carinato.

Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
At the base of the elytra the striation consists of series of very fine but closely 
placed punctures; at the extremity, however, these series are deepened so as to form 
shallow striz. ‘The mentum is polished and shining, without punctures; and there are 
also only a few punctures on the middle of the breast and mesosternum. ‘The fine, 
only very slightly elevated carina of the prosternum is peculiar to this species of 
the genus, and, in combination with the less punctate surface, renders it very readily 
identified. 
Mr. Champion has sent three individuals.
