THE CANADIAN ENTOMOLOGIST jr,- 



.fifth segment with yellow triangles at anterior angles ; pile slightly shorter 

 throughout; cheeks without distinct b'.ack spots, and pallidly yellow. Oherwise 

 similar to the male. 



Six specimens, Teulon, Man., May to Sept. (Dr. A. J. Hunter). 



From ribesii it differs in having the antennae red ; thorax darker, antennae 

 less pointed ; spot below the eyes ; femora of female, black at base ; the first pair of 

 spots reach the n:argins in n.uch greater width than in ribesii. From rectus it 

 differs in the color of the antennse, legs, and narrower abdominal bands. From 

  protritus, to which it is closely related, in having the legs in both sexes largely 

 black. 



Syrphus opinator O. S. 



Easily recognized. Squamae pilose above; first abdominal band reaches 

 the margin, the two following narrowly separated from margin ; venter of female 

 usually without black markings, venter of male with an elongate transverse black 

 spot on second ventral and two broad complete black bands on following 

 segments. 



A western species which occurs west of the Rockies and as far east as 

 Alberta in Canada. Five specimens from California (Davidson), B.C. (C. B. D. 

 Garrett), and Alta. (Walsh). 



Sjrphus torv'us O. S. 



Readily distinguished by the presence of pile on the disc of the squamae 



and pilose eyes. The species may be recognized at a glance by the elongate brown 



stigma and the presence of blackish spots on the venter, which are quite different 



from those in other species. The first spot is roundish, the second triangular, 



■and the third usually extends wholly across the posterior margin of the third 



.ventral. The base of the hind femora of the female is black. 



A widely distributed and common speciesw I have specimens from Cal., 

 B.C., Man., Out. and N.H. 



The above species constitute an unusually interesting group in the genus 

 Syrphns and so far as I am aware there are no other European or North 

 American species which have the disc of the thoracal squamae hairy. Three of 

 the species, S. torvus, vitripennis and ribesii, are common to Europe and North 

 America. The species which follow all lack the pile on the disc of the squamae 

 but several are closely related to those above described. 



Syrphus grossulariae Meigen. 



A large beautiful species in which the abdominal bands extend over the 

 side margins in their full width, including the basal spots. The wholly black 

 antennas and absence of pile on the disc of the squamae and the black haired 

 scutellum will readily distinguish this species. 



I have a melanic female from Orillia in which the bands are shining 

 metallic greenish with a reddish color distinguishable in some lights. 



Syrphus xantliostomus Will, has the abdominal bands broader, the 

 antennae reddish and the scutellum yellow pilose. 



Syrphus reflectipennis new species. 

 Eyes pilose ; face with rather broad median black stripe ; thorax metallic 

 blackish blue, the scutellum similar, with a yellowish translucent reflection;
