Piceous ; palpi and disk of thorax darker ; head, antennae, 

 apical half of abdomen, and valves of terebra, blackish. Antennae 

 2 28-jointed, longer than the body, somewhat incrassated towards 

 the extremity ; 1st joint of flagellum nearly as long as the two 

 following together. Prothorax rugulose. Mesothorax beset with 

 large distant punctures, between which are a few minute longi- 

 tudinal scratches. Metathorax elongate, deplanate, punctulate, 

 more thickly than the mesothorax, but with smaller punctures ; 

 the smallest specimen has some traces of arese on the metathorax ; 

 not so the others. Wings subfumato-hyaline, narrow, elongate ; 

 stigma pitchy testaceous, with a fuscous circumscription ; nerviures 

 pale fuscous. Legs, including the coxa, pitchy testaceous. Abdo- 

 men wholly smooth and shining. Terebra ^ longer than the body. 

 Male unknown. Length, If — 2 ; wings, 3 — 3^ lin. 



This insect has remained unknown since the time of 

 Haliday, who published no description of it, but made a 

 sketch of the wings, reproduced in Van Vollenhoven's 

 ' Schetsen.' From this source Dr. Capron and I 

 succeeded in identifying four females in his collection 

 taken at Shiere, near Guildford. I have since seen two 

 more, taken near Brussels, among the unexamined 

 specimens of Wesmael's collection.
