which are not in view from above. Elytra convex, impunc- 

 tate, the basal fovea of the sutural Hne smaller than the 

 rather large fovea of the discal impression. Abdomen not 

 carinate at the base. 



Habitat. Gulf States. Not known to us. 



T. puNCTicoLLE, Lcc. Rcd-brown, convex. 



Head with the occiput not impressed in the middle, the 

 fovese small, connected with the middle of the frontal margin 

 by nearly straight grooves. Prothorax convex, longer than 

 wide, widest near and before the middle line, the lateral foveas 

 large, connecting sulcus deep, scarcely angulatein the middle; 

 the disk finely and distinctly punctulate. Elytra wider be- 

 hind, with two large basal fovese, sutural line deep, discal line 

 very short. Length 0.9 mm. 



Habitat. Arizona. Not known to us. 



T. THORACicuM, Brciid. Saftirated yellow; form slender; 

 pubescence very fine, abundant. Length, 0.9-0.95 mm. 

 Plate XL, Fig. 95. 



Head narrower than the prothorax, one-fifth wider than 

 long, tempora convergent, eyes not prominent, base impressed 

 in the middle, frontal margin straight, a little more than half 

 as wide as the width across the eyes; the fovete are in a line 

 with the middle of the eye, mutually less than twice as distant 

 as either from the eye, circumambient sulcus distinct, shallow, 

 antennal tubercles small. AntenncE one-half longer than the 

 head, the two basal joints not as strong as in T. farvidnm ; 

 eighth to tenth equal in length; each twice as wide as the 

 preceding one, the last one-fourth longer than its width and 

 twice as wide as the tenth, ovate. The last palpal joint in 

 outline securiform, but not compressed. Prothorax as long 

 as wide, seemingly longer, equal to one and one-half times 

 the length of the head, widest before the middle, sides evenly 

 arcuate, not perceptibly sinuate near the rather small lateral 

 fovcce which are connected with the small medial basal fovea 

 by a straight sulcus one-fourth the length of the prothorax 

 from the base; disk evenly convex, finely and densely punc-
