Antennz dark reddish-fuscous, almost black. Head and pro- 
thorax black, with long and thick black hairs. Palpi dark testa- 
ceous. Mesothorax dark piceous. Anterior wings broad, entirely 
smoky fuscous, dorsal margin darker; long black hairs on the 
cubital veins; a small whitish spot at the thyridium ; veins fus- 
cous. Posterior wings smoky subbyaline, darkest at the apices ; 
veins fuscous. Legs dark testaceous, with black spines. Abdo- 
men blackish above, brown beneath. In the male the upper 
margin of the last abdominal segment is considerably produced 
but regularly rounded off; app. sup. obtusely triangular or 
rounded, hairy; app. intermed, short and concealed; app. inf. 
rounded, blackish and covered with long black hairs. In the 
female there is a tubular piece, which is notched above and pro-

Not a common species, frequenting canals and still waters, and 
appearing at the end of summer and in autumn. London, Exeter, 
Burton-on-Trent and Hastings are known localities. It isan insect 
that F have never seen in the day-time; it probably conceals 
itself at the roots of reeds, &c., not appearing till it is quite dark. 
Specimens have been taken at sugar by Lepidopterists.
