 Oregon, Washington Terr. Readily recognized by the abdominal segments 

 being broadly banded and bordered behind by brilliant brassy or bronze, 

 the fourth segment in the male wholly so. The first segment in the 

 male with a narrow posterior border extending across from its side 

 spots. 



pp.— Abdomen very l)road, thorax densely pilose, very large species 



Hadromyia Wlstn, 1. c. 



Hadromyia grandis Wlstn., 1. c. Washington Terr. The present 

 species is the largest Syrphid of which I have any knowledge ; it measures 

 nearly an inch in length by a third of an inch in width across the abdo- 

 men. 



oo. — Face produced, longer than the front. 



q._Face produced forwards, pointed, concave from antennae to tip, not 

 tuberculate, subcarinate, eves of male contiguous or nearly so in 

 front of ocellar tubercle, ^hind femora thickened, usually with 

 bristly points below, abdomen without yellow markings. Crioprora. 



A.— Dorsum of thorax beset with thick or yellowish or yellowish-rufous 

 pile, on the pleura black ; wings with brownish clouds along the 

 veins. 



a. — Front in female broad, beset with yellow pile ^alopex O.S. 



b. — Front in female narrow, beset with black \)\\e..femorata, sp. nov. 



B. — Dorsum of thorax beset with long grayish or whitish pile, above on 



pleurae yellowish-white, abdomen dark bluish-metallic (in the male 



with black opaque second segment, and a black opaque cross-band on

I have never seen a specimen of cyanogaster ; it is probably distinct 

 from cyanella, although the description applies quite well to my female 

 cyanella. A comparison is needed of specimens from the Atlantic and 

 Pacific States in order to make the description of Loew's species more 

 complete. 

 *Crioprora ALOPEX O. S., West Dipt., 338 (Pocote). California. 

 Crioprora cyanella O. S., 1. c, 339. California. Osten Sacken's 

 description, as usual, is quite accurate. 

 Crioprora femorata, sp. nov. 



(j"$. Everywhere deep shining black. Front in female narrower 

 than in cyanella, with black pile, eyes in male less contiguous than in 

 cyanella ; the face a little less produced and more obtusely pointed. An- 

 tennae reddish-brown, arista yellow. Thorax and scutellum with rather 

 abundant yellow pile, black on the iileurae. Abdomen with a brassy re- 

 flection, black pilose, intermingled with longer yellow on the sides of the 

 second segment. Legs wholly black pilose, the anterior tibiae and tarsi with 

 golden pubescence. Hind femora in the male much thickened in the male 

 and bent with a row of short spinous tubercles below, posterior coxae obtusely
