LeConte.] ; 904 [Feb. 1, 
The largest of our species and easily recognized. 7. clavi- 
corne Máklin, may possibly be this, but the description 1s 
not sufficiently definite to permit its identification. 
25. Trimium puncticolle, n. sp.—Elongate, red-brown; head 
with an angulated line, ending behind ; in small fovee ; occiput broadly 
convex, not impressed. Prothorax convex, longer than wide, rounded on 
the sides in front, narrower behind; fovez large, connecting line deep, disc 
finely and distinctly punctured. Elytra oblong-ovate, wider behind ; basal 
fovex large, sutural stria deep, dorsal stria short. Length .9 mm. .055 
inch. 
Arizona; many specimens were found in an ant’s nest by 
Dr. Horn. 
26. Trimium simplex, n. sp.—Very small, pale, rufo-testaceous, 
less shining, finely pubescent. Head with a deep, angulated impression, 
ending each side behind in a large fovea. Prothorax convex, longer than 
wide, with a large basal fovea on the declivity of theside, connecting trans- 
verse line obsolete. Elytra not very convex, bifoveate at base, sutural stria 
distinct, dorsal stria very short. Length .5 mm.; .02 inch. 
Tampa, one speeimen. This is the smallest Pselaphide 
known to me, being smaller even than 7. americanum. 
Four other species of Trimium in my collection, though 
not belonging to this zoölogical district may here be conve- 
niently described. 
97. Trimium discolor, n. sp.—Elongate, chestnut-brown, slightly 
pubescent, abdomen darker. Head with two small fovee, and an arcuated 
frontal impression ; vertex slightly punctulate, convex, faintly channeled 
or foveate behind. Prothorax longer than wide, convex, with a deep, an- 
gulated impression near the base, which terminates in a small, lateral fovea 
upon the deflexed part of the sides. Elytra bifoveate at base, outer fovea 
deeper than in the other species, sutural stria fine, dorsal one short. An- 
tenne and legs ferruginous. Palpi short, a little longer than the 1st and 
9d joints of the antenne: the 9th and 10th joints of the latter are trans- 
verse. Length .9 mm.; .085 inch. 
One speeimen, Louisiana. I have adopted the name pro- 
posed by Dr. Zimmermann. 
og. Trimium foveicolle, n. sp.—Elongate, bright rufo-testaceous, 
very slightly pubescent. Head convex, smooth, with a fovea each side 
above the eyes, and.a transverse angulated frontal impressed line. Pro- 
thorax longer than wide, convex, with three sub-basal fovee, connected 
by a transverse impressed line; the lateral fove® are larger, and situated 
on the declivity of the sides. Elytra bifoveate at base, sutural stria deep, 
dorsal one short. Antenne with 9th and 10th joints transverse. Length .9 
mm.; .035 inch.
