2. Tegulae with only the extreme cephalic angle edged with 

 black, sometimes wholly yellow. 



Anterior tibiae black interiorlj^ only in the middle ; from 

 direct lateral aspect, posterior tibiae as in the other species 

 but the band of black along the inner margin is very narrow 

 and there is a transverse black ring across the tibia at 

 its middle hyalinipennis 



1. Tumidicoxa nigra n. sx>. 



Female. Length 6,25 mm. Opaque black, the second abdo- 

 minal Segment, the posterior coxae and the mesopleura shining. 

 Marked with yellow as follows: The distal half of the tegula, the 

 distal third of the cephalic femur, the distal fonrth of the inter- 

 mediate femur, a moderately large subreniform spot at the extreme 

 distal outer angle of the caudal femur; all of the cephalic tibia 

 except the middle and proximal portion interiorly, all of the middle 

 tibia except interiorly which is black nearly to each end, the black 

 not extending to the spurs, however, and all of the posterior tibia 

 excepting the proximal end, the ventral side (excepting a band of 

 yellow near proximal end, the inner lateral side excepting for the 

 same yellow band and at tip and the ventral edge of the outer, 

 lateral side); tarsi all yellow excepting the extreme tip of the distal 

 tarsal Joint. Antennae black. Body bearing short golden-yellowish 

 pubescence, more or less clumped at the apex of the scutellum. Fore 

 wings slightly fuscated throughout, a some-what more pronounced 

 longitudinal streak along the venation and along the caudal wing 

 margin opposite the submarginal vein; also a minute darker pro- 

 jection from the apex of the stigmal vein on a line with it. 



Ring Joint of antennae short, scape nearly as long as the pedical, 

 ring Joint and first two funicle joints combined; funicle Joint 1 longest, 

 one and a half times longer than 2, the latter and 3 subequal, 

 4 times the size of the pedicel; 4, 5, 6 and 7, subequal, each some- 

 what shorter than the one preceding, 6 and 7 somewhat wider than 

 long; funicle joints projected somewhat at their disto-lateral angles; 

 club quadrate ovate, the distal Joint longest, the proximal Joint not 

 as long as Joint 7 of the funicle and wider than long; club blunt 

 at end, truncate.
