the thorax is uniformly yellowish, but im the one from 
Studland it has three brown stripes, while in another it is 
entirely dark brown; this last specimen has the wing 
darkened at the tip and along the hind margin. Hypo- 
pygium, figs. 24 and 25.

Head blackish; palpi yellow; antennae dark brown. Thoraa’ 
reddish-ochreous. Abdomen discoloured but apparently in life it 
must have been entirely ochreous. Genitalia as in figs. 26 and 27. 
Legs yellowish; tarsi and tibial spurs dark. Front tibiae hardly 
as long as the metatarsi. Wings slightly yellowish-tinged; a 
small dark apical spot on the costa. Tip of Sc immediately above 
base of R, ; third costal division about three-quarters as long as 
fourth; R.+, long, at an angle of about 45° with R,+;; costa 
extending half the distance between the tips of R,+; and M,+,; 
anal vein distinct, almost reaching margin. Length about 4 mm. 
1 g. New Forest, vii. 1905 (D. Sharp.). The general 
aspect of this species is extremely like P. flava, from 
which it appears to be distinguished by the shortened 
anal vein. The name is suggested by the comb like 
appendage of the hypopygium. P. ochracea, Mg., is also 
similar but is larger, and there are several differences in 
venation. 
*P. nigricornis, F. (= nigriventris, Ztt., = antica, Wlk.. 
= infuscata, Winn.). New Forest (D.S., F.J.); | Monks- 
wood (D.8.); Crowborough, Cambridge (F.J.). I have 
little hesitation in adopting Fabricius’ name for this species. 
He describes the abdomen of the female as having the 
borders of the segments yellowish; this is often the case, 
though typically the female abdomen is entirely black. 
The thorax of the female generally has more or less distinct 
indications of three darker stripes. Hypopygium, figs. 
28 and 29. 
P. fasciata, Mg. The hypopygium (figs. 30 and 31) 
seems to be indistinguishable from that of Lundstrém’s 
P. tristis, and his species is therefore very likely a dark 
variety of P. fasciata. The latter is not uncommon with us. 
*P. unicolor, Staeg. Apparently not at all uncommon, 
Logie, Cambridge, Crowborough (F.J.); New Forest 
(D.8.); Clacton-on-Sea (J.W.Y.). This species might be
