specimen was derived. This fact is commented on by Chevrolat 

 who in 1874 (Rev. et Mag. ZooL, 1874, p. 278) placed this species as 

 a synonym of damicornis Fabr., but later on (M^moire, 1876, p. 42) 

 the same author stated that it was very distinct from damicornis. 

 No species or this or neighboring genera known to the author seems 

 to be referable to this species, the occurrence of which within our 

 faunal limits is extremely doubtful. Chevrolat's varieties C and D 

 (Rev. et Mag. ZooL, 1874, p. 329) described from Cuba, may possibly 

 be identical; Chevrolat, however, places them as synonyms of dami- 

 cornis Fabr. The figure given by Spinola represents an insect some- 

 what similar in form and markings to Chariessa pilosa var. onusta 

 Say, the form being, however, slightly more Slender; the head is 

 narrow ; the prothorax as long as wide, quadrate; the head, antennae, 

 elytra (sutural and lateral margins excepted), and the legs dark 

 brown; the thorax reddish. The structure of the antennae is similar 

 to that of the female of C. pilosa. The antennae are eleven-jointed ; 

 the funicle is clothed with rather long sparse hairs, the three terminal 

 joints forming a large, lax club, the inner margin of which is finely 

 pubescent. The length as indicated on the plate is 12 millimeters.

This species appears to be quite rare in collections, in fact the 

 writer has seen but three specimens which were, beyond doubt, 

 texana. Damicornis occurs in many collections labeled as texana. 

 Indeed these two species are so variable in color that forms occur 

 which, upon color alone, may be assigned to either of the species; the 

 sculpture is also nearly identical. The writer is unable to give any 

 distinctive characters of a stable nature to aid in their recognition, 

 other than those employed in the table following damicornis. Usually 

 however, in texana the thorax is dark piccous; the antenna^ (except 

 club) reddish; the upper surface clothed with long, yellowish, rather 

 conspicuous hairs, and the legs arc black. The elytra are" a little 

 more coarsely, and the thorax is slightly more densely punctate than 

 in damicornis. 



An example before the writer has the basal half of thorax dull 

 reddish; in another specimen only the extreme apical margin of the 

 thorax and the legs are reddish, with the knees and tibiae very slightly 

 in'fuscate. 



This species has been reported as occurring at Washington, D, C. 

 It is known to the author from Texas only.
