clothed all over with abundant, rather long, deep yellow hairs, no black hairs 
being intermixed even round the edge of the scutellum or on the sides of the 
thorax; alule whitish-yellow; halteres luteous, tip of the knob brownish-black ; 
abdomen black, with its edge considerably recurved, dull and roughened on 
the second, and disc of the third, segments, moderately and regularly punctate 
on the shining, rather zneous, fourth segment; the pubescence is rather abun- 
dant, all reddish-yellow; legs black, the tibiw, the tarsi, and the tip of the 
femora luteous, the tibiz and tarsi marked as I have mentioned above; the hind 
meta-tarsus is large and long, but very slightly dilated; the femora have a tolerably 
abundant pubescence, and there are sometimes some black hairs intermixed with 
the luteous ones behind the front pair, and there are also (as in many other species) 
short black bristles beneath the hind femora: the wings have a strong yellowish tinge 
along the costa and about the base, the veins being yellow, except at their tips, the 
transverse veinlet is very distinct, dark brown, and across the lower transverse vein 
let and base of the cubital vein is a slight dark band, and a slight dark blotch or cloud 
near the end of the cubital cell. In the female the eyes are rather thinly hairy; 
the pubescence is altogether shorter and less conspicuous; the front is broad, with 
three longitudinal channels, the middle one being faintest; and just below the 
middle is a distinct transverse channel; the antennz are rather larger, altogether 
reddish-yellow; the abdomen is more elliptical. 
This species was captured by Mr. J. H. A. Jenner in some num- 
bers in Bathurst Wood, near Battle, Sussex, in April. The males fly 
about in the rides, high up in the air, like C. flavicornis G ; the females, 
of which Mr. Jenner only took one, are lower down on the shrubs, &c. ; 
I have likewise seen a female in Mr. W. C. Unwin’s collection, and 
which was also probably caught in Sussex. 
12. Chilosia longula, Zett.: Mr. B. Cooke sent me this species to name, 
and Mr. J. C. Dale also possesses it; it has not previously been 
taken out of Sweden, whence Zetterstedt records three specimens. 
It is one of the bare-eyed, black-legged group, but is distinguished 
by the pale knees and smoky-black alule. 
13. Helophilus frutetorum, F.: the asterisk may be removed from this 
in my list, as Mr. Marshall possesses a New Forest specimen. 
14. Xylota abiens, Meigen: when I published my list I had seen only 
one spotted species of Xylota; but Mr. Cooke having sent 
me specimens of two others, I found that the one I possessed 
(though named nxemorwm by Loew) was X. abiens of Meigen, 
known by its smaller size, by the short spine on the hind 
trochanters of the male, by the thick (not very thick) bind ~ 
femora, and the bluish hue often visible on the abdominal 
spots; I captured a pair at Abbott’s Wood in Sussex, on June 
28th, 1867, and Mr. Cooke has a male and Mr. Dale a female.
