coxae black. Wings a dark yellotvi.sh brotvn at the base, exteiuling in a somewliat 
lighter l)ro\vnish sliade over the entire wing, which is narrow and gradually tapering 
towards the apex. 
$ . Front slightly covered with a golden yellow tomentnm, easily denuded, 
leaving the upper part a polished Itlack. ( )n the abdomen the long hairs are less 
prominent, and the entire surface is covered by a yellow tomentum, a dorsal line and 
spots of whitish tomentum on the sides of the third and fourth segments being

This species has been collected at the following places in New Jersey; — Iona, 
June 2, ’02, (Daecke) ; Atco, June 18, ’93; Jamesburg, July 4, ’94; Orange Mts., Jidy 
4, ’96; Morris Plains, .June 24, ’92 and Dover, June 25, ’92 (Johnson). In Connecti- 
cut, at New Haven, June 27 (E. J . S. Moore) and in Massachusetts at Springfield, Jidy 
2 and 10, ’99; ]Mt. Tom, .June 26, ’00, and .Inly 14, ’0.5 (D iminock)-, West Chop, 
July 4, ’93 (A. P. Mor.se), Provincetown, June 27 and Hyannis Port, July 3, ’04 
(John.son). In the list of New .Jersey Diptera, this species was confounded with 
subvarivs (lanrifei). It can however be readily distinguished from both .subi'arius 
and fulvib(i.sis by its dark evenly clouded wings, which are noticeably narrower and 
more gradually tapering, especially in the male, and also Jty the shorter proboscis. 
It appears in greater numbers at least a month later, than fuleibasis. 
The types, (<J' Provincetown and 9 Hyannis I^ort) are in the New England 
collection of the Boston Society of Natural History. 
BoiiBYLius VALiDUS Jmew. 
This large species I have not been aJ)le to obtain on any of my collecting trips, 
and there seems to be no date bearing on its time of appearance. It is widely dis- 
tributed, being recorded from “Ga., Va., 111., N. Y., and Montreal.” 1 have a speci- 
men marked “Tex.,” (Bolter). It is readily distingui^icd by its noticeably long 
bright yellow pile ami long proboscis. The dark Iiro^n of the wings extends in a 
slightly lighter shade over the entire surface.
