170 Mr. R. E. Turner on the 



carina on tlie second ter<;ite and the paitial development of 

 the second transverse vein of tlie anal cell. 



Gymnoficelus rujithorax, sp. n. 



(S . Gracilis, uiger ; thorace rufo ; segracnto niediano nigro, rugoso ; 

 alis hyalinis, venis fuscis ; auteuiiis 32-arliculatis ; tarsis intor- 

 mediis articulis teitio quartoque pallide brunneis. 



Long. 6 mm. 



cJ . Head broader than the thorax, finel}' and closely punc- 

 tured, the face more closely punctured than the vertex and 

 clothed with short white pubescence; clypeus truncate at the 

 apex; cheeks about half as lon<^as the eyes; frontal excava- 

 tion very shallow and ill-defined, a low carina from between 

 the antennoe to tlie anterior ocellus. Thorax finely and closely 

 punctured ; the median lobe of the mesonotum not prominent ; 

 parapsidal furrows clearly defined, finely crenulated. Basal 

 half of the scutellum depressed and strongly longitudinally 

 striated ; median segment very coarsely rugose, not areolate. 

 Abdomen very slender, as long as the head, thorax, and 

 median segment combined ; the tirst tergife nearly as long as 

 tiie remainder of the abdomen, gradually broadened from the 

 base, three times as long as its apical breadth, transversely 

 rugulose, with two longitudinal carinas from the base ex- 

 tending for fully three-quarters of the length of the tergite, 

 the extreme apex smooth and shining. Hind coxoe closely 

 and finely punctured and sparsely clothed with white hairs, 

 hind calcaria very short. First discoidal cell sessile, anal 

 cell with two transverse nervures ; second abscissa of the 

 radius nearly twice as long as the first, equal in length to the 

 second transverse cubital nervure, only half as long as the 

 cubital margin of the cell ; second transverse cubital nervure 

 straight, forming a right angle with the cubitus.

This differs from typical Ui/mvoscelus in the very shallow 

 and almost obsolete frontal excavation, in which point it 

 approaches Asjiidocolpus. But the second transverse vein in 

 the anal cell is present as in (Jymnoscelus.
