63. Scenopinus lincinus, new species 



Figure 64 



This is one of several species which have female terminalia differing 

 from those of most of Scenopinus, in that the sternum is a little longer 

 than the tergum, rounded, and the ninth tergites have short stiff hairs 

 or spines. Based on the configuration of the bursal plates, all appear to 

 be distinct species. The present species is closely related to S. fraternus 

 and S. nitidulus as previously mentioned, as well as S. fryeri, S. re- 

 duncus and perhaps S. longiventris. The males of the last three are 

 unknown and the similarity of the males of the first two have already 

 been mentioned. 



Fei\la.le. — Head black-brown; eyes dark red-brown; a broad, sunk- 

 en postocular ridge; frons broad, subshining, with a median dimple; 

 ocellar tubercle set off from frons; ocelli red-brown. First antennal 

 segment black-brown, short; second segment red-brown, twice as 

 large as first; third segment black-brown, pear-shaped, covered with 

 gray pollinose scales, with a ventro-lateral pit. 



Thorax black-brown, subshining; humeral callus red-brown, supra- 

 alar callus tan. Wings smoky brown; veins brown, R5 and Ml + 2 

 both curving forward to end before the tip of the wing; halter stem 

 brown, knob tan. Legs black-brown; femora with sparse short hairs; 

 tibae and tarsi with short hairs. 



Abdomen red-brown, subshining; for details of the terminalia see 

 figure. 



Male. — Unknown.
