THE CANADIAN ENTOMOLOGIST. 291 



Pulvilli straw-coloured. All bristles and pile not mentioned, pale or deep 



rufous. Wings hyaline, slightly fuscous along the brown veins. Length, 



14.5 mm. 



This species may be readily distinguished from Loew's adiistus and 



combustus, the types of which I have seen, by its more slender body and 



the lack of any blackish tinge to the wings. It may be distinguished from 



Johnson's bicolor and abbreviaius, the types of which I Have also seen, by 



its long, slender abdomen. 



Described from one female captured August 2, Tehachapi, California, 

 by A. P. Morse. Type specimen in collection of Mr. Charles W. Johnson. 



Sarapogon albifrotis, sp. nov. — ^. Face white, thorax brownish- 

 yellow, abdomen rufous. Length about 10 mm. 



Head everywhere white pollinose ; ground colour of face pale straw, 

 of occiput black. Eyes, ocelli, proboscis, and distal half of third antennal 

 joint black. Bristles of mystax, pile of segments i and 2 of antennae, 

 proboscis, and testaceous palpi, and hair of ocellular tubercle, occiput and 

 beard, white ; last very slight. Thoracic dorsum and upper portion of 

 pleura and scutellum brassy-yellow pollinose. Lower portion of pleura 

 and the coxse whitish pollinose. Pile of thorax confined chiefly to dorsum, 

 very short, white ; bristles and halteres whitish. 



Abdomen rufous, slender, somewhat shining. First segment, 

 especially on sides, spot on posterior angles of four following segments 

 white pollinose ; spots on segment 5 very sniill, and in one instance 

 lacking. White pile most abundant on segment 1, elsewhere extremely 

 scarce and short. Legs pale rufous ; distal margins of trochanters and 

 claws black; pulvilli whitish. Two anterior pairs of coxte with moderately 

 long white pile; femora, tibi?e and tarsi with very short pile of same 

 colour. Tibise and tarsi with sordid white bristles,, longest on the 

 intermediate pair. Wings pure hyaline with slight violaceous tinge ; veins 

 brownish at base of wing, darker outwardly. 



This species is smaller than either adustus or combustus, and is 

 nearer them in form than bicolor, abbreviatus or rufus. 



Described from 2 females collected by F. H. Snow, Bill Williams 

 Fork, Arizona, August. One is a somewhat worn specimen, and has lost 

 its antennje. Two female co-types, one in the collection of the Massa- 

 chusetts Agricultural College and one in that of the University of Kansas.
