The length and width of the prothorax in this species is 

 ver}'^ deceptive; seemingly it is longer than wide but drawing 

 and measuring prove the dimensions to be nearly equal. 



T. RUFiCEPS, Lee. [T. integer., Lee.) Dark brown, 

 elytra darker; surface polished, impunctate, pubescence short 

 and fine. Length 0.7 mm. 



Head large, longer than wide, occipital foveae mutually as 

 far distant as either from the eye, connecting sulcus arcuate 

 anteriorly. Antennce 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, foveas, 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. Elytra 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 poHshed, sutural lines deep, slightly arcuate, two 

 elongated impressions near the base, of which the outer one 

 is the larger. Abdomen without carinje, narrower than the 

 elytra at the base. Legs slender, tarsi short, somewhat 

 thicker in the middle, claws minute. 



Habitat. Michigan, Ilhnois, 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, 

 foveae, 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. 

 Antennas short, not more than one-third longer than the head,
