115 



leriorly, sparsely clothed with long, semierect, white hairs; anterior margin with 

 a large, broad, median lobe. Anterior femur with a large, moderately acute 

 tooth, which is dentate on outer margin. Anterior tibia arcuate, with a slight dila- 

 tion at apex; middle and posterior tibiae straight. 



Length 6.5 mm., width 2.75 mm. 



Female. — Differing from the male in having the front of the head more sparsely 

 punctured, the antenna bronzy brown, the last visible sternite more narrowly 

 emarginate at apex, the eighth tergite rounded at apex and longitudinally cari- 

 nate, and the anterior tibia unarmed at apex. 



Redescribed from the male holotype and female allotype in the col- 

 lection of J. N. Knull. 



Type locality. — Davis Mountains, Tex. 



DISTRIBUTION 



From material examined: 



Texas: The only specimens examined are from the type series collected from 

 May 25 to June 13, 1935, by J. N. Knull, and a female from Texas (without a 

 definite locality) in the Academy of Natural Sciences of Philadelphia, under 

 axillaris, labeled paratype No. 3429. 



Host.' — The larval habits of this species are unknown, but the adults 

 have been collected in Texas by Knull on the branches of dying cat's- 

 claw {Acacia constricta Benth.), which may be its host plant. 



No variation worthy of mention was observed in the specimens 

 examined, except in size, the range in length being from 6.5 to 7.5 mm. 



This species is closely allied to axillaris, but it differs from that 

 species in having a large coppery-red spot on the head and pronotum, 

 and the anterior tibiae coppery red.
