various Central American Coleoptera. 127 
(Flohr); Brrrish Honpuras, Rio Hondo (Blancaneaux) ; 
GUATEMALA, Zapote, Aceituno (Champion). 
Six specimens, sex not ascertained. Apparently a rare 
but widely distributed insect. 
MiIcROscYMNUS, n. gen. 
Maxillary palpi (fig. 5b) very stout, the last joint subconical ; 
antennae (fig. 5a) apparently 11-jointed, joints 1 and 2 very stout, 
‘8-11 dilated into an oblong club; eyes very large, depressed ; 
anterior tibiae (fig. 5) broadly widened, sulcate above for the recep- 
tion of the tarsi, and received in repose in a deep groove in the 
anterior femora, the other tibiae moderately widened and imperfectly 
suleate for the reception of the tarsi; coxae widely separated ; 
intermediate and posterior femora received in deep grooves, which 
extend outwards across the elytral epipleura and are limited behind 
by the curved, cariniform coxal lines, the groove for the posterior 
pair extending forwards into the metasternum; tarsi 3-jointed, 
short, joints 1 and 2 strongly lobed beneath, the claws appendiculate ; 
ventral segments 2—4 very short, 5 as long as 2-4 united; body 
spherical, glabrous above. 
Type, M. calvus. 
The minute Scymnid from which the above characters 
are taken is a fairly common insect in Central America. 
It was rejected from the Coccinellidae by Gorham, and 
one of our specimens is marked “ ? Histeridae,” owing to 
its convex, glabrous, shining body, and the broadly dilated 
anterior tibiae. These characters are quite sufficient for 
the recognition of the insect. There is apparently a 
minute node at the base of the terminal tarsal joint. 
*Microscymnus-calvus, n. sp. (Plate IV, figs. 5, 5a, 6.) 
Very convex, shining, black, the antennae, mouth-parts, and legs 
flavo-testaceous, the inter-ocular portion of the head and the sides 
and under surface of the thorax sometimes similarly coloured. 
Head and thorax closely, the elytra more sparsely, punctulate. 
Beneath shining down the middle, the ventral segments 2-5, and 
the sides of 1, alutaceous and more or less punctulate. 
Length 1-11 mm.

and Tamahu in Vera Paz (Champion).
