130 Mr. R. E. Turner on the 



of punctures before the apex and rounded anteriorly, the 

 second with a transverse, longitudinally striated groove at 

 the base ; the third sparsely and finely punctured at the base 

 and apex ; the fourth and fV'th more closely punctured; the 

 epipygiutn coarsely punctured-rugose at the base, smooth and 

 shining at the apex. The first recurrent nervure is received 

 just before the middle of the first cubital cell, the second just 

 beyond the middle of the second cubital cell. 



Black ; the mandibles, the apex of the pygidium, and the 

 spines of the tibiae and tarsi ferruginous brown ; antennas 

 fusco-ferruginous beneath and at the extreme apex. Wings 

 hyaline, tinted with yellow, stigma and nervures ferruginous. 



Length 9 mm., exp. 14 mm.

<$ . Clypeus finely and very closely punctured, the an- 

 terior margin truncate. Front finely and very closely 

 punctured, thinly clothed with long, pale, fulvous pubescence, 

 the space round the ocelli shining, sparsely and more coarsely 

 punctured ; the scape finely punctured, shining and clothed 

 beneath with rather long, pale fulvous pubescence. Pro- 

 notum finely and closely punctured, the posterior margin 

 rather narrowly smooth and shining; propleurae finely and 

 obscurely striated, smooth and shining at the top. Meso- 

 notum and scutellum shining and rather sparsely punctured; 

 the median segment subopaque, with the usual three carinas, 

 the two outer carinas more than twice as far apart at the base 

 as at the apex : finely punctured, aciculate near the lateral 

 margins, the sides of the segment closely striated ; the meso- 

 pleurse rather sparsely punctured. Abdomen closely punc- 

 tured, with sparse fulvous pubescence, the first segment rather 

 short, the apical half smooth and shining, with a transverse 

 vow of fine punctures before the apex, the second segment 

 more sparsely punctured than the following one. Radial 

 cell short, the second cubital cell extending beyond it, the 

 second transverse cubital nervure strongly oblique and inter- 

 stitial with the oblique apical nervure of the radial cell. The 

 first recurrent nervure is received at the middle of the first 

 cubital cell, the second just beyond the middle of the second 

 cubital cell. 



Black ; the pubescence on the sides grey, on the dorsal 

 surface very pale fulvous ; the antennae beneath fusco- 

 ferruginous, the tarsi except the basal joint, and the spines 

 of the tibiae and tarsi ferruginous. Wings hyaline, stigma 

 and nervines ferruginous.
