THE CANADIAN ENTOMOLOGIST 275 



broad lateral. Abdomen with a narrow black dorsal vitta, which is obsolete 

 on apical portion of basal segment; hypopygium glossy black. Legs yellowish 

 testaceous, coxae, femora and tarsi largely fuscous, sometimes the femora almost 

 entirely fuscous,- or almost entirely pale. Wings slightly grayish, yellow at 

 bases. Calyptra and halteres yellow. 



Eyes separated at narrowest part of frons by a distance equal to width 

 of anterior ocellus; parafacial at base of antenna about half as wide as third 

 antennal joint, much narrowed below; cheek as high as width of third antennal 

 joint, with a few long bristles along lower margin, one of which is upwardly 

 curved, antennae reaching nearly to mouth-margin; arista with very short 

 pubescence. Thorax with 2 or 3 pairs of presutural acrostichal bristles and a few 

 intermixed setulose hairs; prealar less than half as long as the bristle behind it. 

 Abdomen short, depressed, parallel-sided; hypopygium large; fifth sternite in 

 both specimens before me projecting downward, darge, the processes slightly 

 curved, rounded at apices, their inner halves furnished with dense, erect black 

 hairs, a rounded elevation laterad of base of each process on each of which there 

 are a few bristles. Fore tibia with a short, sharp apical posterior bristle; mid 

 femur with a few bristles near base on postero- ventral surface; mid tibia with 

 1 postero- dorsal and 2 posterior bristles; hind femur with antero- ventral 

 bristles long and widely separated, the postero- ventral surface with a rather 

 closely placed series of short bristles on basal three- fifths; hind tibia with 1 

 ^antero- ventral, 2 antero- dorsal, and 2 postero-dorsal bristles; mid and hind 

 tarsi shorter than their tibiae. Costal thorn sm.all, outer cross- vein slightly 

 curved, veins 3 and 4 subparallel apically, the former terminating almost in 

 the apex of the wing which is slightly pointed. 



Length 5.5 mm. 



Type and paratype, Godbout, Quebec, Canada, July 25, 1918, (E. M. 

 Walker). Named in honour of the collector. 



The series of short bristles on basal two- fifths of hind femora and the 

 fringes on processes of fifth abdomiinal sternite distinguish this species from 

 any known to me. 



Type in the Royal Ontario Museum of Zoology, Toronto. 



Hylemyia quintilis, sp. n. 



Female. — Black, shining, rather densely gray pruinescent. Head entirely 

 black, the orbits and parafacials with white tomentum, the remainder of head 

 with less dense pruinescence. Thorax with 5 poorly defined brown dorsal 

 vittce. Abdomen more distinctly shining than thorax, with a large pa;tch of 

 gray pruinescence on each side of each tergite posteriorly. Legs black. Wings 

 with a yellowish brown tinge, veins dark brown, yellow basally. Calyptrae 

 white. Halteres yellow. 



Frons over one- third of the head- width, a little widened anteriorly, orbits 

 well defined, each about one- fourth as wide as interfrontalia at anterior ex- 

 tremity of ocellar triangle, and with 3 bristles in front of lower supraorbital 

 bristle, otherwise bare, interfrontalia with a pair of strong curciate bristles, and 

 a few microscopic hairs on each side, ocellar triangle with 2 long bristles and 

 several long setulae, parafacial at base of antenna wider than height of cheek 

 and a little wider than third antennal joint, narrowed below, the vibrissal angle 

 much produced, anterior upper margin of mouth forming a sharp ridge which
