Maryland, southward to Texas; found on the leaves of j'oung oaks, on 

 the under surface of which the insect sits, and falls to the ground when 

 approached, as observed by Zimmermann. The hind legs, though long 

 and powerful, are not saltatorial, as, indeed, is evident from their form 

 and position; but being widely separated, and capable of lateral exten- 

 sion, they give to the insect a grasping power which is very great in 

 proportion to its small size. The curious movements in which, when 

 about to alight it turns itself back downwards, and seizes the leaf with 

 the elongated curved hind legs, are very well described by Zimmer- 

 mann, in the passage above cited. 



2. T. centralis Lee, Trans. Am. Ent. Soc. ii, 55. 



Raton Mountain, Colorado, on Bhus aromaticum. The hind thighs 

 are rather serrulate than toothed, the hind tibitB are straight, not flat- 

 tened. The color is uniform black, the elytral stria? are somewhat con 

 fused, and the white spot is verj' small. 



3. T. tardipes, n. sp. 



Pale brown, head, middle of prothorax, liody beneath, hind legs in part, 

 scutellum, and four large spots on the elj'tra, blackish. Body above 

 thinly clothed with long, erect, gray hairs; prothorax not densely punc- 

 tured, with a tuft of tine, soft, whitish hair at the basal angles. Elytra 

 with rows of deep subquadrate punctures, interspaces narrow convex; 

 with an angulated sutural spot in front of the middle, of soft, white hair, 

 and a few scattered small tufts of the same; each elytron with a large, 

 dusky spot on the humerus, and a smaller round one near the tip. Be- 

 neath strongly punctured, pubescent with erect hair, sides of trunk with a 

 line of soft, whitish hair. Length 2.3 mm. ; .09 inch. 



Texas; one specimen given me by Mr. W. Jiilich; one also in the col- 

 lection of Dr. Horn. The hind thighs are blackish, finely subserrate be- 

 neath; the hind tibia? are longer than the tarsi, pale towards the tip, not 

 flattened, slightly curved, finely subserrate on the outer side; tarsi brown. 



4. T, fulvipes, n. sp. 



Brown, feet uniform reddish testaceous. Body above thinly clothed
