AUT. 34 PLIES OP GENUS PSEUDOTEPHRITIS MALLOCH 5 



PsBUDOTEPHRiTiNA, new Subgenus 



The anterior fronto -orbital bristle is very rarely present as a very 

 short setula but never as a well-developed bristle; the specimens 

 available to me all have a quite distinct spur vein projecting from 

 the posterior side of the fourth vein into the discal cell, and the 

 scutellum is more swollen than in the other subgenus and has two 

 large glossy black spots. The legs are much paler than in the 

 other group, but this is not considered as diagnostic. 



Type species of subgenus, Stictocephala ci'ihellum Loew. 



PSEUDOTEPHRITIS (PSBUDOTEPHRITINA) INAEQUALIS, new species 



Female. — Head testaceous, densely pale gray-dusted, upper occi- 

 put fuscous, frons with numerous oval piliferous reddish dots, no 

 black spot behind ocelli, and the postocular cilia hardly darkened 

 around bases; antennae and palpi testaceous yellow. Thorax fuscous, 

 densely graj^-dusted, mesonotum and pleura with many dark-brown 

 piliferous punctures, a large black mark covering postalar region 

 on which there is a group of black setulose hairs; scutellum gray- 

 dusted, with a large glossy black mark on each side at apex. Abdo- 

 men fuscous, yellowish at base, densely gray-dusted, tergites 2 to 4 

 each with an apical dark brown fascia, the fourth with some small 

 piliferous dots, genital segment testaceous yellow, black on sides and 

 along center below, the hairs dark. Legs testaceous. Wings as in 

 crihellum Loew, but the costal marks preceding apices of auxiliary, 

 lirst, and second veins conspicuously darker than those on the disk 

 of the wing. 



Structurally similar to crihellum, the scutellum thick, with a slight 

 central apical depression. Postalar region quite copiously setulose. 

 Outer cross vein about one-fifth from apex of discal cell. 



Length, 7 mm.
