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. 



Metanaa chapmani. 

 1. Apex of abdomen viewed from above. 2. Apex of abdomen viewed from side. 



Three males, one female, Lauteret, Alps of Dauphine 

 (Chapman, July 22nd, August 5th). Also occurs in Val Bed- 

 retto (Ris, September 6th, 1896 ; July 20th, 1906) : Spliigen 

 (Piis, 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. 



McLachlan gives the following localities iox H. flavipennis: 

 Dissentis, Grisons (July 25th, Stainton), Bergiin (Zeller), Leuk, 

 Valais (October 2nd, Frey Gessner) Hospice St. Bernard; 

 Priitigau and Pontresina according to Meyer-Diir ; Meyringen
