4. Forficula ? sp. 



N. Bengal, Siliguri, i8-20-vii-o8 — $ only. 500/20, 502/20, 

 503/20. 



Body except abdomen absolutely smooth ^ with a rich, glisten- 

 ing green metallic oily lustre : general colour black : abdomen 

 deep chestnut to black, and finely punctulate : last tergite weakly 

 crested at the exterior angles : branches of forceps depressed, 

 straight, stout, and tapering. 



The rich, smooth, brilliant, lustre of the head, pronotum. ely- 

 tra and wings render this a very distinctive species, but I refrain 

 from naming it, as without the male it is impossible definitely 

 to decide its exact generic position.

 brown, smooth, broad, not very long, truncate : wings protruding 

 slightly, dark brown. Legs brown: abdomen jet black, pliciform 

 tubercles very distinct, dorsal surface finely and densely punctu- 

 late: last tergite rectangular, transverse, punctate, not crested:

 arcuate. 



Poona: Khed District, among rubbish in house: No. 1544/19. 



This species very closely resembles the African F. rodziankoi , 

 Sem., differing from the dark macropterous forms of that vari- 

 able species almost solely in the shape of the pronotum, which is 

 almost pentagonal, being obtusely rounded posteriorly with 

 straight and parallel sides.
