246 THE CANADIAN ENTOMOLOGIST. 



segment chat bears it, at apex darker. Region surrounding the ocelli, a 

 space above the antennae, a triangular spot on the face, including the 

 facial callosity and cheeks, shining black ; remainder of the face and front 

 gray poUinose, with sparse white hairs near the eyes. Mesonotum, includ- 

 ing the scutellum, entirely densely clothed with coarse golden hair; pleura 

 with white hair ; wings nearly hyaline, but from certain views they appear 

 slightly clouded; general colour of legs black, with white hair; all the 

 tibiae yellowish at base; first two segments of each of the middle and 

 hind tarsi yellow ; first two segments of each front tarsus dusky, but 

 lighter in colour than the three remaining segments ; all the femora 

 swollen, and with short black spines below on apical parts. Abdomen 

 black, clothed on dorsum with black and golden hair, on sides with white 

 hair ; the black hair of the dorsum is very short, and distributed as 

 follows : the anterior half of the second segment, a rectangular patch on 

 anterior middle of the third segment, occupying two-thirds of the length 

 and over half of the width of this segment, and a triangular patch on the 

 anterior third of the fourth segment. The golden hair is longer and 

 coarser than the black, and most dense on the fourth segment. The first 

 segment, and all the sutures between segments, are thinly gray poUinose, 

 giving the effect to the unaided eye of gray bands. 



Habitat. — Phoenix, Arizona. Taken June i8th. 



The species has most affinities with strigilata, Loew, and auri- 

 cauihita, Williston, but on comparison with the former species in the U. 

 S. National Museum, I find the two have a very different appearance. 

 From the latter the coloration of the abdomen and legs, the lack of 

 "golden tomentum" on the frontal triangle, and the larger size are 

 sufficient to distinguish it. In accordance with what has been observed 

 in related species, 1 should expect that the vestiture of the female is paler 

 than in the male. 



Milesia bella. Townsend. — Several specimens of this beautiful 

 syrphid were taken at Elden Mountain, June 17th. The black front 

 tibiae and tarsi and the thoracic markings easily distin^guish the species 

 from ornata, Say, which is our common eastern member of the genus. A 

 reference to Townsend's fine description in the Annals and Magazine of 

 Natural History, Ser. 6, Vol. XIX., 142, will reveal the characters oibella 

 and its differences from ornata. Townsend's types were taken in 

 southern New Mexico.
