THE CANADIAN ENTOMOLOGIST. 



27. Syrphus co/ijunctus, sp. no v. (Fig. 2.) 



Male. — Face dark yellow, descending almost perpendicularly to the 

 small tubercle, cheeks shining black, the black continued around in front 

 and up over the tubercle to the middle of the face, but interrupted behind 

 the mouth on the oral margin by yellow ; front and vertex black, the 

 former with yellow pollen except near the antennae. Pile of face, front 

 and vertex black. Antennte dark, third joint lighter below. Occiput 

 with yellow pile. Thorax shining bronze-black, with some yellowish 

 pollen on the disc, and with yellow pile, Scutellum large, waxy-yellow, 

 pile yellow, with a fringe of dark hairs on the margin. Abdomen black, 

 segment i shining, 2 opaque, 3 opaque except the lateral borders, 4 

 mostly shining, 5 and the hypopygium entirely shining ; three broad 

 yellow bands occupying the anterior half of the segments, on segment 2 

 the band is interrupted and the spots forming it are rounded at their inner 

 ends and attenuated at their outer ends, where they attain the margin of 

 segment ; on segments 3 and 4 the cross-bands are complete, but are so 

 deeply incised behind at the middle that they appear at first glance to be 

 interrupted, each half evenly rounded behind, and attenuated at the outer 

 end, where it attains the margin of the segment ; segments 4 and 5 are 

 margined with yellow posteriorly, and the outer anterior angles of 5 are 

 yellow. Pile of abdomen mostly black, but yellow on the first two cross- 

 bands. Anterior and middle legs reddish-yellow, black at the extreme 

 base of the femora, and the tarsi infuscated ; hind legs reddish-brown ; a 

 broad dark band covers most of the femur, and the distal three-fourths of 

 the tibia and the tarsi dark. Halteres yellow. Wings hyaline, slightly 

 infuscate anteriorly, stigma brown. 



Length, 8 mm. ((;^^yV/;/^;'?/^ = joined, referring to the apparently inter- 

 rupted abdominal cross-bands). 



Described from one male specimen, taken at Hope, on the Nicolum 

 River, July 14, 1906, by R. V. Harvey. 



Evidently related to S. macidariss Zetterstedt, but differs in having 

 the eyes bare, and the black of the face and legs much more restricted, 

 while abdominal bands 2 and 3 are incised but not interrupted.
