Figure 8. 



Mesonotum reddish yellow, with three black vitta? or spots; pleurae 

 with black spots; abdomen yellow with black bands; middle metatarsi 

 with a row of long bent bristles below; hypopygium small, shining black. 

 Length 4-5 mm. 



Male : Face and palpi white ; eyes narrowly separated at the center 

 of the face; proboscis and antenna yellow, arista brownish; front and 

 occiput black, thickly covered with white pollen; orbital cilia whitish, 

 post-vertical bristles yellowish. Mesonotum reddish-yellow with three 

 black vittse or spots, the central one subquadrate (in one of my spec- 

 imens this spot is missing) , lateral spots oval and quite variable in size ; 

 humeri yellowish white; pleurae pale yellow with white pollen, and with 

 a large black spot in the center, a long spot between the front and 

 middle coxae sometimes connected with the central spot, a small spot 

 above the hind coxae, and the usual small spot in front of the halters; 

 scutellum yellow with the extreme base black; metanotum black, a 

 little shining, and white pollenose. Abdomen yellow with three wide 

 black bands, one near the base of the second segment, and one at the 

 base of the third and fourth segments, these bands widest on the center 

 of the dorsum; fifth segment with a narrow black dorsal line and some- 

 times a very narrow basal band; venter yellow; fifth segment without a 

 ventral sheath. Hypopygium and its appendages shining black, pol- 

 ished, rather small, and with a few scattering pale hairs. Legs pale 

 yellow; front coxae with delicate yellowish hairs in front, and black 

 bristles near the tip; front metatarsi about as long as their tibiae, the 

 fourth joint short, about as broad as long; middle metatarsi nearly as 

 long as their tibiae, and with a row of long bristles on the lower side, 

 these bristles more or less bent backwards at tips; this row of bristles 

 continued on the tibiae but the bristles scattering and straight; hind 

 tarsi, with the first and second joints equal. Wings grayish hyaline, a 

 little darker in front; last section of fourth vein bent forward a little 

 from a little beyond the center, not very close to third at tip; tip of 

 fourth vein a little before the apex of the wing. 



Female: Agrees with the male in all but sexual characters, except 

 that it has only short scattering bristles on the lower side of the middle 

 metatarsi; and the fourth joint of the front tarsi are longer than in the 

 male; in one specimen the lateral spots on the dorsum of the thorax 

 are wanting.

 taken them in the vicinity of Buffalo, N. Y., and at Toronto,

 sent me specimens from Polk Co., Wis., taken in July, from 

 Philadelphia, Pa., taken by Mr. V. A. E. Daecke, June 12, and
