330 THE CANADIAN ENTOMOLOGIST. 



(more broadly so above), a line on the femora above, a line on the four 

 anterior tibia? and tarsi above, and the apex of the posterior tibiae (the 

 posterior tarsi are wanting) black. Wings hyaline, iridescent ; venation 

 black, stigma with a narrow orange-coloured line. 



Male : Length, 5 mm. The male differs from the female in having 

 the antennae longer, the claws not nearly so deeply cleft ; the scutellar 

 appendage is not so granular ; the scutellum is black, the trochanters and 

 the posterior tibia: have a black line above. The stigma is brownish, and 

 the posterior tarsi are black. The hypopygidium is rounded at the apex, 

 not notched. 



Type locality : Mountains near Claremont, California. A male and 

 female collected by Prof. C. F. Baker. The female is in Baker's collection, 

 the male is in the author's. 



This species is near Provancheri, Roh., but the femora have a black 

 line above (they are not black all the way around at the base). 



Macrophya occidentalism n. sp. — Male: Length, 5 mm. Clypeus 

 rather short, the anterior margin incurved ; the labrum about as long as 

 the clypeus, its anterior margin incurved. Supraclypeal fovea transverse, 

 shining; middle fovea linear, not well defined; lateral ocellar furrows deep 

 and narrow to the ocelli, but below the ocelli they are very weak ; orbital 

 carina not strong. The third antennal joint is shorter than joints 4 and 5. 

 The lateral lobes of the mesonotum are more densely punctured than the 

 anterior one ; the scutellum with larger, more scattered punctures ; the 

 scutellar appendage is opaque, perhaps it is granular ; tarsal claws 

 minutely cleft. Dorsal abdominal segments punctured and granular, but 

 not coarsely so. Hypopygidium rounded at the apex, not notched. 

 Black; narrow posterior margin of the pronotum, and the margin of the 

 tegulae whitish. Legs black ; four anterior femora (not to the base) and 

 the tibia?, posterior femora above and beneath (not extending to the base), 

 posterior tibiae, except at the apex, and the four anterior tarsi more or less^ 

 yellowish. Wings hyaline, iridescent ; venation dark brown, the lower 

 part of the stigma pale. 



Type locality : Claremont, California. One male, collected by Prof. 

 C. F. Baker. 



This species is related to nigricortiis, Roh., but the labrum is about as 

 long as the clypeus (in nigricortiis it is much shorter), and the legs are 

 different colour, as shown in the above table.
