88 THE CANADIAN ENTOMOLOGIST. 



black, with yellow on each half, as follows : a narrow dorsal line from 

 anterior border to beyond the suture, a large spot distinctly furcate before, 

 above the base of the wing, an elongate triangular spot before the suture, 

 a small humeral spot narrowly connected with a stripe, which reaches the 

 base of the wing, and which is five or six times as wide posteriorly as 

 where it joins the humeral spot, a rather large geminate spot below the 

 base of the wing, and one or two small spots above the posterior coxa 

 Scutellum yellow, with the base narrowly shining black ; halteres yellow ; 

 legs yellow, except the median part of each femur, which is black ; wings 

 hyaline, stigma and principal veins yellow, third vein not furcate. 

 Abdomen black, with yellow on each half, as follows : a narrow lateral 

 margin connected with a small spot on second segment, an oblique fascia 

 on each of the third and fourth segments, and the rather broad apex of 

 the fifth segment ; venter black, with irregular yellow patches on the 

 middle of the second and third segments. Length, 6 millimeters. 



Habitat : Taken at Vernon, British Columbia, August 8th, 1902. 



On account of the oblique yellow markings on the front, the name 

 obliqmcs is given this species. 



We hesitated at first to describe this species from a single specimen, 

 but as we have studied practically all the types of the species of the genus 

 without identifying the specimen, have concluded to name it. 



Anthrax Harveyi, n. sp.— Ground colour deep black, clothed above 

 with light yellow and golden yellow pile, beneath with black pile. Head 

 black, face and front clothed with black pile, proboscis projecting slightly 

 beyond the margin of the mouth. Thorax clothed on the dorsum and 

 sides with rather long, light yellow pile, on the sternum with black pile, 

 legs black, with black hairs, and all the tibiae with distinct spines, wings 

 hyaline except costal cells and basal areoles, which are black ; the 

 branching of the second and third veins takes place almost opposite the 

 small cross vein, and the common stock of these veins is narrowly mar- 

 gined with black almost to where they branch, halteres yellow, of nearly 

 the same colour as the pile of the sides and dorsum of the thorax. 

 Abdomen with the dorsum clothed with long and rather dense pile, that 

 on first segment light yellow and on the remaining segments golden 

 yellow, a few black hairs at the apex of the abdomen, venter entirely 

 clothed with black hairs. 



Total length 8-10 mm. The species seems to be related iofulviana, 

 hut besides being smaller differs in the colour of the vestiture of the body.
