52 NaTuRAL History BULLETIN. 
The length and width of the prothorax in this species is 
very deceptive; seemingly it is longer than wide but drawing 
and measuring prove the dimensions to be nearly equal. 
T. RuFicEps, Lec. (7. integer, Lec.) Dark brown, 
elytra darker; surface polished, impunctate, pubescence short 
and fine. Length 0.7 mm. 
flead \arge, longer than wide, occipital fovez mutually as 
far distant as either from the eye, connecting sulcus arcuate 
anteriorly. Aztenne short, not one-third longer than the 
head, the last joint as long as the five preceding, acuminate at 
the apex. Prothorax as wide as the head, slightly wider than 
long, anterior and posterior limits arcuate, angles broadly 
rounded; the sides are parallel in the middle, disk moderately 
convex; near the base, in the middle, are two large, pubescent, 
circular, fovez, separated by a short, longitudinal, carina; on 
the sides, near the middle of the length, is an equally large pu- 
bescent fovea; transverse sulcus interrupted. A/ytra slightly 
wider across the shoulders than the head, sides nearly parallel, 
feebly arcuate near the posterior limits; suture one-fourth. 
longer than the base is wide, and one-half longer than the pro- 
notum; disk polished, sutural lines deep, slightly arcuate, two 
elongated impressions near the base, of which the outer one 
is the larger. Addomen without carine, narrower than the 
elytra at the base. Legs slender, tarsi short, somewhat 
thicker in the middle, claws minute. 
Habitat. Michigan, Illinois, Texas, Florida. 
T. CApITULUM, Casey. Red throughout, pubescence fine, 
short, close. Length 1.5 mm. 
Head small, as wide as long, tempora acutely rounded, 
much smaller than the large eyes, occiput sinuate, vertex 
polished, impunctate; in the eye line are two circular, pubescent, 
foveze, connected by a parabolic, equally deep, sulcus, the en- 
closed surface convex; supra-antennal tubercles elongate, 
prominent, the frontal margin broad, depressed in the middle. 
Antenne short, not more than one-third longer than the head,
