PHILONTHUS. 403 
16. Philonthus guatemalenus. 
Niger; capite anguste ovato, thorace elytrisque viridi-aneis, his fortiter vix crebre punctatis, abdomine versi- 
colore ; tibiis margine externo testaceo, interno fusco; antennis extrorsum crassioribus ; mesosterno in 
medio longitudinaliter carinulato. 
Long. 11 millim. 
Hab. GuateMaa, San Gerénimo (Champion). 
This is extremely similar to P. fibularius and P. carinulatus, but the unique example 
indicates, I have very little doubt, a distinct species, as the mesosternum is considerably 
more prolonged backwards between the coxe, and its longitudinal carinula is more 
largely developed. P. guatemalenus is also probably a narrower insect, with 
considerably narrower head, and rather more coarsely punctate hind body. The 
specimen is a female. 
17. Philonthus accedens. 
Niger ; capite subovato, thorace elytrisque eeneis, his fortiter profundeque punctatis; abdomine versicolore, minus 
crebre punctato ; antennis extrorsum crassioribus. 
Long. 14 millim. 
Hab. GuateMata, Capetillo (Champion). 
This is very closely allied to P. fibularius, but is larger and more robust, has the 
elytra more brightly coloured than in most individuals of that species, and with a 
coarser and deeper punctuation, and the hind body more sparingly punctate; the 
mesosternal triangle is a good deal larger than in P. fibularius, but has no trace of 
carination, and the tibie are entirely black. The two examples obtained are females. 
18. Philonthus cribripennis. 
Niger; capite subovato, elytris cyaneis fortiter profundeque punctatis ; abdomine versicolore parce punctato ; 
antennis elongatis, extrorsum crassioribus. 
Long. 13 millim. 
Hab. Guatemata (Champion). 
Var. Paulo major, abdomine minus parce punctato. 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
This is closely allied to P. fibwlarius, but has the antenne longer, the penultimate 
joint being as long as broad, the elytra of a dark blue colour, with remarkably deep 
and coarse punctures, and a quite scanty punctuation of the hind body. The meso- 
sternal triangle is larger than in P. jfibularius, and has no trace of carination. The 
unique example has not been ticketed with its exact locality ; it is a male, but the 
front tarsi are not dilated. 
The variety from the State of Panama is illustrated only bya badly preserved female, 
and I think is very probably distinct ; it is rather larger, and has the elytra a little 
longer, rather more finely punctate, and the punctuation of the hind body rather greater.
