transversely striated; the latéral apical arese more finely, closely 

 and obliquely striated; the spiracular closely rugosely punctured, 

 and sparsely striated. Metanotum regularly areolated, the basai 

 area distinct, of equal width throughout, one half longer than 

 wide; the areola twice longer than wide; the base rounded, the 

 apex transverse. Except at the apex above, the propleurse 

 are striated, the striai more or less roundly cnrved. The meso- 

 pleural dépression is striated; the striée moderately strong, 

 oblique and clearly separated.

There are large raised, rounded tubercles on the sides of the 

 3 nl , 4 Ul and 5 Ul segments, which are more shilling than the rest of

 bulla near the centre of the disco-cubital nervure at the apex of the 

 stump, 2, almost united, on Ihe fore part of the 2 ad transverse cubi- 

 tal and 2 on the récurrent nervure.
