are very slightly curved downwards, these processes also tuberculate, 
more densely so towards the apex which thereby becomes black. 
Superior appendages pale yellow with rounded outline when seen 
from the side, concave internally. Intermediate appendages viewed 
from behind, separate, each arising from a narrow stem and spreading 
out in broad triangular form with three distal projections, the two side 
ones small, the other long, horn-like, slightly inturned with a small 
tooth before the apex. Inferior appendages large; from beneath 
they are close together at the base, diverging slightly, concave 
internally, rounded at the apex, which is very slightly inturned and 
clothed internally with short spines and spinous hairs. 
I am unable satisfactorily to describe the female. Differences 
probably exist in the genitalia as compared with H. flavipennis, and 
these could very likely be defined from Canada- balsam preparations. 
Expanse of wings, male, 19-20 mm.; female, 21 mm.

Three males, one female, Lauteret, Alps of Dauphiné 
(Chapman, July 22nd, August 5th). Also occurs in Val Bed- 
retto (Ris, September 6th, 1896; July 20th, 1906): Splugen 
(Ris, July 16th, 1897), uncertain whether from the Swiss or the 
Italian side, probably the latter; Madonna di San Martino 
(July 29th and August 1st, 1889, Nageli in Ris coll.). 
Differs from H. flavipennis, especially in the direction of the 
blackened processes of the last dorsal segment. These in H. 
flavipennis are turned to the side almost at right angles to the 
long axis of the abdomen, whereas in H. chapmani they are 
nearly parallel, only very slightly out-turned. 
MeLachlan gives the following localities for H. flavipennis: 
Dis&ey/zis, Grisons (July 25th, Stainton), Bergun (Zeller), Leuk, 
Valais (October 2nd, Frey Gessner) Hospice St. Bernard ; 
Priitigau and Pontresina according to Meyer-Dur; Meyringen 
(McLachlan, August 16th), Champery, Valais (Haton, August 
20th), Samoéns, Savoy (Eaton, September 5th) ; Carinthia (Sep-
