CLEISTOLOPHUS.—BUFOMICRUS. 145 
Scape of antenne slender; second joint of funiculus elongate, longer than the first 
joint. Rostrum parallel, a little carinate on each side in front, and depressed between 
the carin, a small fovea between the eyes. Thorax nearly or quite as long as broad, 
very coarsely and irregularly punctate. Elytra elongate and slender, with very large 
punctures occupying the greater part of the surface, these becoming finer behind; the 
squamosity rather scanty, except on the apical part. Legs stout, the femora with but 
few scales. 
We have a series of eighteen examples to represent this species; it appears to be 
distinct from C. similis, though both are variable. The male is more linear in form 
than the female, and in this latter sex there is a slight longitudinal incrassation along 
the middle of the apical portion of the last ventral plate. 
BUFOMICRUS, gen. nov. 
Corpus breve, squamosum. Antenne scapo modice elongato, oculorum marginem posteriorem attingente. 
Scrobes profunde, angustz, laterales. Femora, vel omnia vel anteriora, dentata. Metasternum brevis- 
simum. 
The insects forming this new genus are remarkable on account of their broad, sub- 
circular elytra. The mentum is large and completely conceals all the palpi. The 
rostrum is short, not any broader at the tip; the scrobes are deep, curvate, entirely 
lateral, sharply defined; the eyes are convex. ‘The anterior cox are placed very near 
the front of the prosternum, which is not incrassate. The middle legs are but slightly 
separated and the metasternum is remarkably short. The corbels of the hind tibiz 
are feebly cavernous. ‘The claws are free. 
These characters bring the genus very near to Lpicerus, but the dentate femora, in 
conjunction with the peculiar shape of the body, are sufficient to distinguish it. One 
of the three species I place in it—JB. cristatus—may have to be separated. 
1. Bufomicrus squamosus, sp.n. (Tab. VI. fig. 10.) 
Dense griseo fuscoque squamosus, breviter setosus, elytris transversim subvariegatis; prothorace minus 
elongato ; femora omnia dentata. 
Long. 53 millim. 
Hab. British Honpuras (Blancaneaux); Guaremata, Teleman, La Tinta, Chacoj, 
Tamahu, San Juan, Panima, all in Vera Paz (Champion). 
Scape of antenne clothed with scales and hairs; second joint of the funiculus slightly 
longer than the first. Rostrum and head densely clothed with scales, nearly flat, the 
former very slightly concave in front, the latter with a minute fovea between the eyes ; 
the eyes slightly convex. Thorax not so long as broad, much rounded at the sides, very 
closely covered with scales that conceal the sculpture. Elytra very short and broad, at 
the base only as broad as the thorax, then becoming rapidly broader, densely covered 
with scales, and bearing numerous short, semi-erect sete; the scales are usually
