Type.— C^t. No. 42824, U. S. N. M. 



Described from a single male collected flying around cut down 

 trees at the type locality, May 21, 1925, by Ferd. Nevermann. 



This species is allied to sanguinolenta Bates, but it differs from 

 that species in being larger, the antennae robust but with the inter- 

 mediate joints widest, and the pronotum and underside of the body 

 uniformly black, except the base of the posterior tibiae and femora, 

 which are pale yellow. 



ODONTOCERA DARLINGTONI, new species 



Female. — Form similar to that of fasciata Olivier. Head and 

 pronotum yellow, the latter ornamented with black markings as 

 follows: A large, transverse triangular spot, including the anterior 

 margin; a large, straight, transverse fascia in front of scutellum, 

 but not extending to the lateral margins ; a transverse sinuate fascia 

 at middle extending nearly to the coxal cavities, which is more or 

 less interrupted externally ; and an elongate spot at middle connected 

 posteriorly to the median fascia, but not extending to the transverse 

 spot in front of scutellum ; antennae reddish brown ; scutellum yellow, 

 with the base blackish ; elytra pale yellow, vitreous, with the lateral 

 and sutural margins narrowly I'eddish brown, and each with an 

 arcuate blackish fascia extending ffom the humeral region back-

 epistoma, flat between the eyes, and with a longitudinal groove 

 extending from vertex to frontal depression; surface glabrous, 

 coarsely, irregularly and vaguely punctate in front, becoming finely 

 punctate or granulose on the occiput. Eyes separated from each 

 other on the front by about one and one-half times the width of the 

 labrum. Antennae short, extending to base of first abdominal seg- 

 ment; joints 1 and 2 shining, and rather densely, coarsely punctate, 

 the following joints subopaque, densely pubescent, and some of the 

 joints armed with long, erect hairs on the inner margin; joint 1 

 robust, slightly arcuate, and gradually clavate; joints 2 to 4 sub- 

 cylindrical, the third twice as long as the fourth, which is slightly 

 more robust and feebly enlarged toward apex; joints 5 to 10 serrate 

 and about subequal in length; joint 11 oblong, acute at apex, and
