PHILONTHUS. 407 
Hab. Mexico, Cordova (Sallé); Guaremana near the city, San Gerénimo, Zapote, 
Capetillo, Calderas, Cerro Zunil, Lanquin, Senahu and San Joaquin in Vera Paz 
(Champion); Panama, Bugaba, Volcan de Chiriqui 2000 to 4000 feet (Champion). 
Very closely allied to P. vilis, but with the thorax, elytra, and hind body quite black, 
the head slightly broader, and the male posterior tibie slightly curved and a little 
thickened towards the extremity. The tibie and the coxe are more or less infuscate, 
but the femora are pallid yellow. The middle coxe, as in P. vilis, are contiguous, and 
the front feet of the female are moderately, those of the male rather broadly, dilated ; 
in this latter sex there is a deep notch on the last ventral plate. 
This is apparently a common species throughout most of our region, and varies a 
good deal'in the minor details. The description is taken from a long series, agreeing 
pretty closely, found at San Gerénimo. One of these is figured. In other cases the 
base of the antennze becomes darker, and occasionally the elytra are picescent ; and such 
an example is labelled in Sallé’s collection, “ P. caliginosus, EK. Dugés, in litt.” 
29. Philonthus occultus. 
Fuscus ; prothorace piceo, antennarum basi pedibusque piceo-testaceis; capite ovato, prothorace antrorsum 
angustato; elytris crebre punctatis ; abdomine dense subtilissime punctato. 
Long. 7 millim. 
Hab. Guatemata (Sallé). 
Antenne shorter than the head and thorax, but little thicker towards the apex, the 
penultimate joints each very nearly as long as broad. Head much narrower than the 
thorax, the latter rather longer than the elytra. Hind body very densely, evenly, and 
finely punctate. 
This is an obscure species, of which only a single example has been received ; it is a 
male and cannot be treated as an extreme variety of P. ochromerus, on account of the 
sexual characters, the front tarsi being broadly dilated and the front tibize short and 
thick, while the hind tibiz are simple; there is a large notch on the last ventral plate. 
30. Philonthus planulatus. 
Subdepressus, niger, nitidus; elytris «neis, femoribus fusco-testaceis; capite subquadrato; elytris parce 
profunde punctatis ; abdomine parce subtiliter punctato. 
Long. 8 millim. 
Hab. Panama, Volcan de Chiriqui 3000 to 4000 feet, Pefia Blanca 3000 to 4000 feet 
(Champion). 
Antenne black, scarcely thickened outwardly, the penultimate joints not quite so 
long as broad; palpi rather long and slender. Head as broad as, or broader than, the 
thorax, extremely shining, quadrate, but with the hind angles greatly rounded. Thorax 
not narrowed in front, narrower than the elytra, very shining, and, like the head, with a
