170 Mr. R. E. Turner on the 



carina on the second tergite and the partial development of 

 the second transverse vein of the anal cell. 



Gymnoscelus rujithorax, sp. n. 



$ . Gracilis, niger ; thorace rufo ; segrnento mediano nigro, rugoso ; 

 alia hyalinis, veuis fuscis ; antennis 32-articulatis ; tarsis inter- 

 mediis articulis tertio quartoque pallide brunneis. 



Long. 6 mm. 



£ . Head broader than the thorax, finely 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 long as the eyes; frontal excava- 

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

 the antennae to the 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 first tergite nearly as long as 

 the remainder of the abdomen, gradually broadened from the 

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

 rugulose, with two longitudinal carina? from the base ex- 

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

 the extreme apex smooth and shining. Hind coxaa 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 nervuie 

 straight, forming a right angle with the cubitus.

This differs from typical Gymnoscelus in the very shallow 

 and almost obsolete frontal excavation, in which point it 

 approaches Aspidocolpus. But the second transverse vein in 

 the anal cell is present as in Uymnoscelus.
