Median segment transversely rugosely punctured ; much 

 more strongly at the base than at the apex ; the centre at 

 the base bears a slightly raised, bordered fovea, about 

 three times as long as broad and rounded at the apex. 

 The base of the propleurae raised in the middle, finely 

 rugose at the base, running into fine striations. Meso- 

 pleurae strongly punctured, sparsely covered with a dark, 

 microscopic pile ; the lower two-thirds of the base is 

 obliquely depressed, this depression having at the apex a 

 clearly defined, curved border ; the apex very smooth and 

 shining, and having in front a stoutly crenulated border. 

 The basal part of the metapleurae closely, the apical 

 rugosely punctured, and running into reticulations ; the 

 depression at the top behind the spiracles rugosely punc- 

 tured at the apex ; the apex shining, smooth, except for 

 some stout keels near the middle. All the coxae and 

 trochanters are black; the hinder tarsi are black; their 

 basal joint on the under side thickly covered with stiff, 

 longish, dark fulvous pubescence. Wings fulvo-hyaline, 

 the fulvous tinge not so conspicuous at the apex ; the 

 stigma fulvo-testaceous ; the nervures blackish ; the cubital 

 nervure at the base and the first transverse cubital nervure 

 pale fuscous ; the areolet narrowed at the top, oblique ; 

 the transverse cubital nervures are almost united at the 

 top ; the recurrent nervure is received in the apical third. 

 The apices of the abdominal segments are narrowly 

 obscure testaceous ; the depression on the petiole is smooth 

 and shining; the sides coarsely and closely punctured; 

 the middle with the punctures slightly smaller and more 

 widely separated ; the extreme apex smooth; the second 

 to fifth segmehts closely and strongly punctured, but 

 the punctuation becomes gradually weaker; the sixth 

 segment aciculated ; the apical smooth. The tegulse are 

 pale dirty testaceous in front, black behind.
