Diptera) Part II. 



By CHARLES P. ALEXANDER, Urbana, Illinois. 

 This paper is a continuation of the first part under this 

 title (ENTOMOLOGICAL NEWS, vol. xxxi, pp. 215-221. 1920). 

 The material herein considered was sent to me by my friend, 

 Serior Charles Bruch, and is based principally on specimens 

 sent him by Engineer VVeiser, collected in the Puna Region 

 of the Province of Jujuy. The types are preserved in the 

 writer's collection.

 with an indistinct brownish ring ; wings yellowish white with a sparse
