EN DOMYCHIDAE. 
MICROPSEPHUS. 
Micropsephus, Gorham, Biol. Centr.-Am., Coleopt. vu, p. 
149 (1891). 
The type of this genus is a minute, globose, shining 
insect, not unlike an Aspidophorus, with 11-jointed antennae 
(joints 1 and 2 long and stout, 1 curved and longer than 
2, 3-8 very slender and closely articulated, 9-11 dilated 
into a long, loosely-articulated club), stout, compressed 
femora, slender tibiae, slender, elongate, 4-jointed tarsi, 
widely separated intermediate and posterior coxae, and 
an elongate first ventral segment. The additional species 
now added from Central America has the intermediate 
antennal joints more slender and reduced in number, but 
otherwise agrees perfectly with M. mniophilinus. The 
Antillean insect described by Gorham (Proc. Zool. Soe. 
Lond., 1898, p. 338) under the name Dialexia punctipennis 
is very like M. hemisphaericus, and also has 9-jointed 
antennae, but it differs from the latter in having basal 
sulci to the thorax, etc. 
*Micropsephus hemisphaericus, n. sp. 
Orbicular, convex, shining, nigro-piceous above, piceous beneath, 
the antennae and legs testaceous. Head, thorax, and elytra 
impressed with closely placed, small, conspicuous punctures; an- 
tennae 9-jointed, 1 and 2 long and stout, 3-6 very slender, 3 
elongate, as long as 4-6 united, the latter strongly transverse, 7-9 
dilated into a long, stout, loosely-articulated club. Tibiae and tarsi 
very slender. 
Length 1,,-14 mm.
