INSECUTOR INSCITI^ MENSTRUUS 159 



Habitat. — New Zealand (South Island). 



Holotype, a wing in balsam, Little River, Canterbury, Jan- 

 uary 12, 1921 (Gourley). 



This wing is preserved in the writer's collection through the 

 kindness of Dr. Campbell and Mr. Gourley. The location of 

 the remainder of the type-specimen is not known to me at this 

 time but may possibly be in the collection of Dr. Tillyard at 

 the Cawthron Institute. 



The details of the wing venation lead me to refer this fly 

 to Nemopalpus rather than to Bruchomyia. Compared with 

 N. molophilinus, the present species is notable by its large size, 

 the long Sc, Sc^ ending opposite r-m, and the sessile cell M-^, 

 the r-m crossvein connecting with M^+o exactly at the fork. 

 More material may demonstrate that the generic reference is 

 incorrect.
