92 Trans. Acad. Sci. of St. Louis. 
from the base, where it is nearly as wide as the elytra, to the apex, 
where it has gradually become narrower; head parallel, very coarsely 
and remotely punctate; prothorax as long as wide, equal in width to 
the head, the punctures rather large, sparse and irregularly disposed, 
except single series along the median smooth line; elytra just visibly 
wider than the prothoraxand distinctly longer, nearly as long as wide, the 
punctures not fine, rather sparse and partially arranged in series almost 
throughout; abdomen finely and sparsely punctulate. Male unknown. 
Length 6.4 mm.; width 1.1 mm. Florida..............parcum Lec. 
Form rather stout, parallel; head large, wider than prothorax, parallel, not 
very coarsely but deeply, rather closely punctate, the antennae thick, 
submoniliform, almost as long as the head and prothorax, the latter 
about a fifth longer than wide, distinctly narrower and a little shorter 
than the elytra, the sides feebly convergent and nearly straight from 
apex to base, the punctures small, feeble, rather close-set and irregu- 
larly arranged throughout, with a wide median impunctate line; elytra 
somewhat longer than wide, the punctures fine, feeble, sparse and con- 
fused; abdomen very finely, rather densely punctulate; legs pale. Male 
with the fifth and sixth ventrals wholly unmodified on the disk, the 
apex of former very broadly, angularly emarginate, the latter somewhat 
more deeply and angularly emarginate, both throughout the entire 
width, the latter emargination apparently about six times as wide as 
deep. Length 8.0 mm.; width 1.25 mm. Louisiana........pedale Lec. 
Form slender but convex; sides of the head slightly converging behind the 
eyes, the basal angles broadly rounded, the punctures very fine, feeble 
and remotely scattered; antennae slender, distinctly longer than the 
head and prothorax, the latter wider than the head, just visibly longer 
than wide, convex, parallel, finely, very feebly, indistinctly, sparsely 
and irregularly punctate; elytra not wider than the prothorax and dis- 
tinctly shorter, quadrate, feebly, sparsely and irregularly punctate; 
abdomen darker in color, finely and extremely densely punctulate, dull 
in lustre. Male having a rounded discal impression in apical half of 
the fifth ventral, the apieal margin not modified, the sixth segment 
with a small acutely cuspidiform emargination at tip, the surface not 
modified. Length 4.5 mm.; width 0.7mm. Michigan....bieolor Lec. 
The narrowing of the head behind the eyes in serzatum, 
the peculiar coloration of parcwm and the sexual characters 
of pedale and bicolor, make any definite generic assignment 
of these species impossible in the absence of the types; it is 
hoped, however, that enough characters are given to allow 
of identification in case they should be rediscovered. Bicolor 
is a preoccupied name in Lobrathium, but the sculpture of 
the body is very unlike that prevailing in Rey’s genus, where 
the punctures are especially coarse and close-set throughout 
in all the species known to me; so the name should stand.
