PHILONTHUS. 413 
(as in numerous other species I have at present placed in, Phélonthus) distant from the 
anteriorly much inflexed side margin, yet I cannot place it in Hesperus, of which it has 
not at all the facies, and from which it differs in numerous details, such as having the 
mesosternal line in the condition normal in Philonthus. 
Two males and one female of P. platypterus have been found; the male has the 
anterior femora angularly dilated in the middle behind, but there is no emargination of 
the last segment; this sex is figured. 
44, Philonthus corticalis. 
Depressus, niger ; abdominis apice rufo-testaceo, stylis analibus nigris ; capite subquadrato, prothorace posterius 
angustato; elytris abdomineque crebre sat fortiter punctatis. 
Long. 94 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
Though closely allied to P. platypterus this is a smaller and narrower insect, with 
only the apical segment and the hinder part of that preceding it red; the terminal 
armature though red has the greater portion of the styles black. 
The only example found is pretty certainly a male, though the only indication I see 
of this is that the trochanters of the hind legs are prolonged and have a slender free 
termination. 
45. Philonthus godmani. (Tab. X. fig. 20.) 
Nigerrimus, capite thoraceque violaceo-cyaneis, elytris fulgidis vel purpureis vel auratis; elytris abdomineque 
parcissime punctatis. 
Long. 10 millim. 
Hab. Mexico, Orizaba (Sallé) ; Guatema.a, Calderas 1200 feet, Panajachel 5000 feet, 
San Gerdnimo 3000 feet (Champion); Panama, Boquete 3500 feet (Champion). 
The antenne are only moderately long, slightly thickened externally, the penultimate 
joints not quite so long as broad. The head is not broad, only as broad as, or not quite 
so broad as, the thorax, the eyes not prominent, the hind angles much rounded. The 
thorax is narrower than the elytra, nearly straight at the sides, and nearly parallel- 
sided. The scutellum is coarsely punctate. ‘The hind body, pointed behind, bears only 
a very few punctures, and is of a shining, intense black colour. 
This beautiful insect is apparently rare, only one or two examples having been found 
in each locality; they bear no external marks of their sex, although I have little doubt 
I have both sexes before me; the tarsi are in all quite simple. The Mexican example 
was labelled in Sallé’s collection P. trochilus. Solsky’s description of P. trochilus, 
though indicating a similarly coloured insect, states that the head is large, and that in 
the female the feet are subenlarged, so that it must be different from our species. The 
example figured is a variety with golden-green elytra from San Gerénimo ; it is impos-
