(1.) L. sexpunctatus Say, (Mycetoph.) Journ. Acad. V, 261; Lec.

Piceous, depressed, moderately shining, each elytron with three yellow 
spots. Thorax sub-opaque, moderately densely punctate. Elytra densely 
punctate, shining, sparsely pubescent and with semi-erect hairs in rows.

Pennsylvania, South Carolina, Illinois. This species and 
the next are the only ones with distinct basal thoracic im- 
pression and with a depressed form of body.

The form, color and sculpture resemble the preceding species. The pu- 
bescence of the elytra is rather more evident while the seriated hairs are 
rather less distinct. The color of the elytra is piceous with yellow spots, 
as follows : one humeral, another post-scutellar, often united, a transverse 
band behind the middle angulated in front at the middle of each elytra. 
Length 2-2.75 mm.; .08—.11 inch. 
The terminal joint of the antenn:ze is broader than the preceding, trun- 
cate at tip, and nearly as long as the ninth and tenth together. 
Occurs from Missouri to Colorado, Arizona and California. 
(3.) L. tetraspilotus Lec. loc. cit. 
Oval, moderately convex, piceous, shining, sparsely pubescent. Anten- 
nz with club rather loose, three-jointed, the last joint a little longer and 
broader than the preceding, and truncate at tip. Thorax less coarsely 
punctured than the elytra, intervals between the punctures alutaceous, basal 
impressions absent, basal margin rather suddenly sinuate on each side of 
the middle. Elytra rather coarsely and sparsely punctate, punctures 
vaguely arranged in rows, surface shining, color piceous, with two yellow 
spots on each side, one slightly in front of middle, the other larger, one- 
third from apex, hairs all semi-erect and in distinct rows. Length 2 mm.; 
.08 inch.
