pointed. Inferior 1-8 min., concave above, tip upciir\ ed; brown^ 

 subtriangular. 



9. Differs from the male as follows: — Wings much suffused 

 with brown; pterostigma pale brown, slightl}^ longer than in male. 

 A tiny cream-coloured triangular spot on the anteclypeus. 

 Abdomen cylindrical, thicker than in male, 2-8 spotted as in male, 

 but the spots of each segment of a more equal size, those of 8 

 smaller than the rest; 9-10 dark brown. Appendages separate, 

 short, 1 mm., straight, pointed, black. 



A very distinct species, and by far the smallest member of the 

 genus. The pale blue colouring of the spots is remarkable, and I 

 do not know of another species of the CordiiMince which possesses 

 it.
