PHILONTHUS. 399 
Third joint of the antenne slightly longer than the second, fifth and sixth each a little 
longer than broad, seventh about as long as broad, the three following each slightly 
shorter and broader. Thorax short, not so long as broad, the four punctures of the 
discoidal series large and conspicuous. The punctuation of the elytra leaves their 
surface quite shining, and that on the hind body is not coarse. 
The front tarsi of the male are only very slightly dilated, and the apical ventral plate 
bears a broad shallow excision. The species is described from a single male and a 
fragmentary female; but three individuals of the female sex with the anterior parts 
neous, are, I think, only a variety of the same species. The example figured is the 
male above mentioned ; it is much larger and broader than the other sex. 
7. Philonthus fissilis. 
Niger; capite, thorace elytrisque wneis; prothorace lateribus fortiter sinuatis, elytris abdomineque crebre 
subtiliter punctatis; antennis apicem versus vix incrassatis, articulo penultimo quam longitudo vix 
breviore. 
Long. 12 millim. 
Hab. Guatemata, Totonicapam 8000 to 10,500 feet (Champion). 
This is another close ally of P. furvus, and resembles particularly the Costa-Rican variety 
thereof with short antenne, but cannot be united therewith on account of the fact that 
the male anterior tarsi are almost undilated ; P. /issilis has also a shorter thorax than 
P. furvus, and the pubescence of the under surface is less griseous; there may be 
detected an obscure picescence of the inflexed side of the wing-cases. The two 
examples found are both males, and have a broad shallow notch on the last ventral 
plate. One of them has the anterior coxe flavescent ; but I think this is an abnormal 
deficiency of colour, as it is not quite the same on the two sides of the body. 
8. Philonthus griseolus. 
Piceus, griseo-pubescens ; antennis nigro-fuscis, articulo penultimo quam latitudo haud breviore ; prothorace 
lateribus fortiter sinuatis ; elytris abdomineque crebrius subtiliusque punctatis. 
Long. 12 millim. 
Hab. Costa Rica, Irazu 6000 to 7000 feet (Rogers). 
This is another species closely allied to P. fwrvus, but distinguished by its shorter 
thorax and the griseous pubescence of the upper and under surface, as well as by the 
different colour. Judging from a single example it appears about equal in size to the 
smallest example of P. furvus. The male anterior tarsi are strongly dilated, but there 
is only a very shallow excision on the last ventral plate. The unique individual is 
very greasy, and there is probably in good individuals a brassy tint on the anterior 
parts.
