iorly, the others curved outward in front to the humeri; the hairs 

 become gradually larger and end with a large bristle in front of the 

 scutellum, the latter with four large marginal bristles, humeri, post- 

 alar callus and scutellum yellow. Abdomen yellowish, grayish 

 pruinose, with wide triangular markings of black on the posterior 

 margins of the second, third and fourth segments, fifth and sixth 

 with a narrow dorsal line of black. Halteres yellow, posterior 

 metatarsi not dilated, in other respects resembling the male.

 on the second and third abdominal segments. An imperfect 

 female collected at Hammond's Pond, near Brookline, Mass., 

 September 25, 1913, I am referring doubtfully to this species 

 under the varietal name obscura. It lacks the yellow humeri and 

 scutellum, the antennae are entirely black, and the third joint 

 more attenuated. The abdomen is injured so that the markings 

 are obliterated but no yellow is apparent. Length, 3.5 mm. A 

 number of trips have been made to try and secure more specimens 

 of this interesting form, but in vain.
