rugose and sparsely punctate, punctation in the form of irregularly 

 scattered shallow pits, face pubescent, radiately striate, antennae 

 14-segmented, 1st segment large, 2nd subglobular, 3rd and 4th segments 

 subequal, as long as 1 and 2 together, 5th and succeeding segments to 

 11th progressively shorter, 11th to 14th subequal. Pronotum wide in 

 the middle, rugose, mesonotum transversely wrinkled, parapsidal 

 grooves distinct, extending half-way to anterior margin, median longi- 

 tudinal lines not reaching the middle, mcsopleura coarsely aciculate, 

 with a triangular smooth patch beneath wings, scutcllum coarsely 

 rugose, almost coarsely reticulate, basal foveae transversely clou 

 shallow, smooth and shining at bottom, approximate, metanotum 

 rugose. Abdomen smooth and shining, 2nd tergite completely obscur- 

 ing the following segments, posterior margin microscopically punctate, 

 apex dorsally black, dorsal valve prominent, pubescent, ovipositor 

 protruding. Wings hyaline, pubescent, a few of the veins heavy and 

 black, the others faint, radial cell closed, very shi rt, vein at base not 

 much curved, areolet small and indistinct, veins enclosing it almost 

 obliterated, cubitus not reaching basal vein and very faint. Length 

 2-3 mm. 



Male. Black, antennae, face beneath antenna; and around eyes, 

 ocelli, tegulas, coxae, trochanters, femora, tibiae largely, and abdomen on 

 posterior margin brownish or pale brown; sparsely pubescent. Head 

 reticulate, faintly punctate, face radiately striate, antennas 15-seg- 

 mented, all the segments conspicuously grooved or channeled, 3rd and 

 4th segments subequal, longer than 1 and 2 together, succeeding seg- 

 ments to 11th progressively shorter, 11th and following segments 

 subequal. Thorax coarsely rugose, mesonotum tranversely ridged, 

 parapsidal grooves indistinct, almost wholly obliterated by the coarse- 

 ness of sculpture, pleura coarsely aciculate, small median patch smooth, 

 scutellum coarsely rugose, almost coarsely reticulate, smooth and shin- 

 ing beneath rugae, f( iveas large, oval and shallow, with smooth bottoms, 

 separated only by a carina, metanotum rugose. Abdomen smooth and 

 shining, 2nd tergite completely obscuring following segments, posterior 

 margin microscopically punctate. Wings hyaline, pubescent, costal, 

 subcostal, radial and basal veins heavy, black, others faint, radial cell 

 closed, areolet small, indistinct, cubital vein faint and not reaching 

 basal, vein at base of radial cell almost straight. Length 1.5-2 mm.
