 stamm (1889), which is preoccupied in Hemiptera by Bergroth 

 (1883). Type, Dcmoticus soror Egger, of Europe.

 tibiae ; proboscis only moderately elongate, horny, with large labella, 

 cheeks fully one-half eye height, male without orbital bristles. 

 Claws of male elongate. Hind crossvein nearer to bend of fourth 

 vein than to small crossvein, apical cell narrowly open before wing- 

 tip, bend of fourth vein without wrinkle. Frontal bristles descend- 

 ing to middle of second antennal joint, latter being more than twice 

 the length of the somewhat elongate first joint, second aristal joint 

 short, some fine hairs on parafrontals outside the frontal bristles, 

 facialia bare, epistoma strongly produced. Palpi well developed, 

 elongate, a little thickened apically, slightly curved. 



Represented in U. S. N. M. by two male specimens collected on 

 the Rio Ruidoso, White Mountains, New Mexico (Townsend), on 

 flowers of Rhus glabra, 6,500 to 6,700 feet, July 25 and 29, and by 

 type of D. pallidus, male, Denver, Colo. The species is large and 

 robust. 



All three specimens may be considered as A. pallida Coq
