137 



Female. Size same. More coppery than the male, especially on the 

 sides of the thorax and abdomen. Face dark yellowish-gray ; slightly 

 more than twice as long as wide. Posterior femora not ciliated below, 

 hind tibiae not thickened. The wings are brownish, darker anteriorly 

 between the costa and second longitudinal ; the veins black, very narrowly 

 margined with brown. Otherwise like the male. 



Described from five male and four female specimens, col- 

 lected by Dr. Wm. M. Wheeler, in Monterey County, Cal., 

 during July, 1896. 



This species is most closely related to corax Osten Sacken, 

 from which it differs as follows : lamellae nearly white, bor- 

 dered with black ; fore tarsi male plain. In corax the front 

 tarsi are ornamented and the lamellae are nearly black, yel- 

 lowish-brown in the middle only. 



Dolichopiis intentus, sp. nov. 



Femora largely black ; tibiae pale ; cilia of inferior orbit dark ; tegular 

 cilia dark ; wings hyaline ; lamellae of hypopygium small, dusky ; antennae 

 black, third joint long, pointed, with subapical arista. 



Male. Length 4 mm., of wing 3.5 mm. Dark bronzed green dusted. 

 Proboscis dirty yellow, palpi piceous. Face thickly covered with silvery 

 dust, except a small median spot immediately below antennae. Antennae 

 black ; first and second joints subequal ; first two joints more or less shin- 

 ing, densely clothed with ap- 

 pressed short pubescence ; 

 third joint more opaque, the 

 pubescence closer. First 

 joint bristly ; second joint 

 with a terminal fringe of 

 bristles which become longer 

 beneath ; third joint longer 

 than first and second to- 

 gether. Arista subterminal, 

 shorter than third antennal 

 joint. Front violet, metallic, 

 slightly bronze dusted. Post- 

 ocular cilia black. Thorax and abdomen greenish-bronze above, becoming 

 piceous dusted below. Hypopygium piceous dusted, shining inwardly. In- 

 ternal appendages dark ; lamellae small, fuscous without a distinct darker 

 border, fringed with hairs only. Legs plain, dark, with usual bristles. 

 Front coxae somewhat lighter than pleurae, yet silvery. Femora piceous 

 except the yellow tip ; hind femora with two ante-apical bristles. Fore and
