segment strongly punctured, except in the centre at the 

 apex ; in its middle at the base is a depression about 

 twice as long as it is broad ; the base being deeper than the 

 apex, especially in the middle. The base of the propleurae 

 smooth, the apex obscurely punctured, the mesopleurae 

 obscurely punctured at the base, where it is broadly black 

 from near the tubercles ; the basal half of the sternum is 

 black, the black broadly and roundly projecting at the 

 sides ; the furrow on the apex of the mesopleurae is deep, 

 narrow ; the extreme apex is finely punctured on the 

 upper side. Metapleurse rather strongly punctured, except 

 at the base above, where the punctuation is much finer ; 

 the basal depression is deep black ; the keel between the 

 coxae is stout. Legs coloured like the thorax ; thickly 

 covered with long, white hair ; the apex of the hinder 

 coxae, of the hinder tibiae and the hinder tarsi entirely, 

 black ; the calcaria pale yellow. Wings hyaline ; the 

 base with a faint fulvous tinge ; the costa and stigma dark 

 fulvous beneath ; the areolet broader than long ; the 

 second transverse cubital nervure is curved ; the recurrent 

 nervure is received in the apical fourth. Abdomen smooth, 

 except the base of the second segment, which is punctured 

 strongly in the middle ; the third is more strongly 

 punctured and striated in the middle ; the sides rough ; 

 the other segments are smooth; the petiole is broadly 

 depressed in the middle; the second depressed in the 

 punctured part at the base; the second and third seg- 

 ments are depressed across the middle and obliquely at 

 the sides ; the third is broadly black at the base ; the others 

 black in the middle; the black mark rounded at the apex; 

 the marks on the fifth and sixth segments are larger and 

 broader than on the others.
