ADAMS: DIPTBKA APRICANA. 165 



Pipunculus, n. sp.? 



Female : Occiput, front and face opaque gray pollinose ; first 

 two joints of antennae and arista black, third yellow, acuminate. 

 Thorax opaque ; mesonotum brownish pollinose, gray on humeri 

 and sides, former yellowish in ground color ; scutellura brown- 

 ish, pleurae, metanotum and legs feebly gray pollinose, halteres 

 yellow. The abdomen is greased, and consequentl}'^ I cannot give 

 a complete description. In perfect material it is undoubtedly 

 opaque, the ovipositor straight and yellow. Legs largely yel- 

 low ; the coxa?, the front four femora along the superior border, 

 the hind femora broadly in the middle, and the last joint of all 

 tarsi black. Wings hyaline ; stigma yellowish ; the small cross- 

 vein slightly beyond the junction of the first and second thirds 

 of discal cell ; third section of costa about half the length of the 

 fourth. Length, 3.25 mm. ; wing, 4.25 mrn. 



One specimen, collected in May. I believe that this is a new 

 species, but owing to the discoloration of the abdomen I am 

 unable to describe it fully.
