796 MR. E. A. ELLIOTT ON THE 



Length 12 mm.; abdomen 7 mm.; petiole 3| mm.; terebra 

 10 mm. 



Habitat : South India, F. Smith coll. Type in British 

 Museum. 



The type bears a label with the MS. name " F. ruficejis 

 Smith." A red head is very common in this subgenus and in 

 no way distinctive. The rugosity of the head seems more 

 characteristic. This species may be easily known by the colour 

 of the femoral teeth, which appears to be a very constant 

 character.
