various Central American Coleoptera. 89 
Dr. Sharp (loc. cit.) enumerated fifteen species of this 
genus from Central America. The two others unnamed in 
our collection may be described thus :— 
*Tomarus gibbipennis, n. sp. 
Short, broad, convex, moderately shining, brown, the legs and an- 
tennae paler, the latter with joints 9 and 10 nigro-piceous, the tibiae 
also infuscate at the middle, the tarsi testaceous ; sparsely, very finely 
pubescent. Head finely punctate, the eyes small; antennae very 
slender, elongate, joints 5 and 7 much longer than 4, 6, and 8, 8 a little 
shorter than 6, 9-11 dilated into a rather long, abrupt club, 9 as 
long as broad, 10 transverse. Thorax short, transversely convex, 
rounded at the sides, slightly narrowed behind, faintly transversely 
grooved at the base, the base itself very feebly sinuate, the hind 
angles rectangular, the anterior angles prominent; densely finely 
punctate, without basal foveae. Elytra broad, gibbous, subcordate, 
a little more sparsely punctured than the thorax, the humeri 
obtuse. Beneath densely punctate; mesosternum feebly margined 
on each side between the coxae; metasternum unimpressed. Legs 
long and slender. 
Length 14 mm. 
Hab. Mexico, Omilteme in Guerrero, 8,000 feet (H. H. 
Smith). ; 
One specimen. The uniformly brown body, the alter- 
nately longer and shorter intermediate joints of the anten- 
nae, the short, transversely convex thorax, with the base 
subtruncate, and the broad, gibbous elytra, readily dis- 
tinguish 7’. gibbipennis. The apical joint of the antennae 
is abruptly paler, as in the allied 7. picticornis, Sharp, and 
other species of the genus. 
*Tomarus fuscicornis, n. sp. 
Convex, shining, rufo-testaceous, the thorax in great part, the 
elytra with a very large subquadrate patch below the base (not 
reaching the suture) and the apex, the antennae (the two basal 
joints excepted), and the base of the tibiae, piceous; finely pub- 
escent. Head broad, closely, very finely punctate, the eyes small ; 
antennae moderately elongate, slender, joint 5 longer than 4 and 6, 
8 small, transverse, 9-11 rather large and transverse. Thorax con- 
vex, transverse, rounded at the sides anteriorly, sinuously narrowed 
behind, subtruncate and feebly transversely grooved at the base; 
closely, very finely punctate. LElytra convex, ovate, wider and a
