PHILONTHUS. 423 
This species is very closely allied to P. armatipes, but smaller, of blacker colour, with 
considerably shorter hind legs, whose tibie are without median spinules, and are only 
provided with about three very fine hairs, much shorter than those of P. armatipes; 
the basal joint of the hind tarsus also bears a very fine seta on its upper face at the 
apex, but it apparently varies in its development. The male has a small notch at the 
extremity of the last ventral plate. 
The number and disposition of the tibial setee is apparently variable in this species, 
or it may be that there are three or more very similar species differing in this respect. 
but as only one or two individuals have been received from each locality, 1 am unable 
to determine this point. | 
The example figured is from Pefia Blanca; the sete of the hind tibie are so delicate 
as to be only perceptible with a good and powerful lens, and thus are not indicated in 
our figure. 
72. Philonthus deplanatus. 
Subdepressus, piceus ; capite suboblongo, thorace angusto quam elytra fere duplo angustiore, his subtiliter 
minus dense punctatis ; abdomine crebre fortiter punctato. 
Long. 10 millim. 
Hab. Guatemata, San Gerénimo (Champion). 
Antenne pale piceous, moderately long, a little thickened externally, the penultimate 
joints not quite so long as broad, the fifth and sixth each about as long as broad. Head 
a little narrowed behind the eyes, which are slightly prominent; in front with a fine 
channel along the middle, behind with rather numerous distant coarse punctures. 
Thorax elongate and narrow, nearly straight at the sides, slightly narrower behind. 
Scutellum deeply and definitely punctate. Elytra broad, rather finely and sparingly 
punctate. Hind body with the base of each segment coarsely and closely, the hind 
part of each more finely and sparingly, punctate ; the apical segments much more finely 
and sparingly punctured than the basal ones. Legs long and slender. 
This is a very distinct species, of which only a single example of the female sex has 
been found. Although the punctures of the thoracic series are irregular, and do not 
agree in their positions on the two sides, yet I have little doubt it will prove to belong 
to this group. 
73. Philonthus macilentus. 
Angustulus, parallelus, fuscus; antennarum basi pedibusque testaceis, elytrorum sutura et apice rufo-obscuris ; 
elytris abdomineque densissime punctatis ; antennis elongatis. 
Long. 6 millim. 
Hab. Mexico, Cordova (Sallé). 
Var. Elytris lete rufis.
