smooth and shining; tl>e mesonotum and scatellum dull olive j 

 the former with three large, ahnost united, marks hetween the 

 tegulae, keeled down the sides and round tlie apex ; median seg- 

 ment [metathorax] \\'ith a gradually rounded slope, impunctate,. 

 glabrous ; at its base are two large arete, one on either side ; they 

 are broader than tliey are long, and triangularly narrowed at the 

 apex ; from its centre a curved keel runs to the apex of the seg- 

 ment' its apical part being thicker than the basal ; before its 

 middle, on the inner side, and joined to it, is a short, oblique keel : 

 pleurte' smooth and shining, glabrous ; the metapleura; with a 

 curved keel above and below ; the tubercles are distinct. The 

 seutellum, rounded from the base to the apex, not much raised 

 above the mesonotum, but its apex considerably so above thepost- 

 scutellum, whicli is depressed laterally at the base ; the lateral 

 depressions large. [Abdomen'] : tlie first, third, and fifth segment* 

 are broadly marked with black in or near the middle, tlie mark oit 

 the fifth J3eing interrupted; the base of the petiole largely de- 

 pressed ; the inner side of the depression carinate, the keels being, 

 continued into the apical part to near the end of the segment ; on 

 the apical third is a transverse row of deep punctures ; the second 

 to fifth segments are closely punctured ; the transverse depression* 

 are longitudinally striated ; terebra 1 mm. Ler/s stout ; the anterior 

 olive-coloured, as are also the middle coxaj ; the hinder knees are 

 black, the tarsi are infuscated. Wings hyaline, the stigma blackish, 

 the nervures paler ; the areolet is shortly appeudiculated ; the 

 recurrent nervure is received in the middle. 



" Length 8 mm. 



" The^colour of the abdomen and legs is doubtful, as the ferru- 

 ginous tint of the abdomen and legs may be caused by chemical 

 discoloration ; but structurally it is distinct from any of the yellow 

 species. The scutellum is more distinctly keeled at the apex than 

 in the yellow species, the apical and the lateral keels being- 

 continuous."
