Antennz brown, with paler annulations. Head reddish-brown, 
blackish anteriorly. Palpi reddish. Prothorax reddish-brown, 
with long slightly darker hairs. Mesothorax blackish, with two 
impressed reddish median lines. Anterior wings broader than in 
L. griseus, rusty brown, with numerous small pale dots, a row of 
fuscous dots in the middle towards the base, and sometimes a few 
similar dots on the dorsal margin ; pterostigma brown ; fenestrated 
spot and the indistinct anastomosal space greyish-yellow, and there 
is also a greyish-yellow spot, often indistinct, on the inner side of 
the pterostigma; veins fuscous, with pale dots, the anastomosis 
conspicuously darker. Posterior wings greyish-hyaline, brown- 
ish-grey at the apex; veins brown, the ramus discoidalis forks 
sooner than the ramus subdiscoidalis. Legs reddish-brown with 
black spines, the apices of the tibize and tarsi slightly fuscous. 
Abdomen blackish, reddish-ochreous beneath, and with lateral 
lines of the same colour. In the male the upper margin of the 
last abdominal segment has a rounded projection in the middle, 
bent under, black and scabrous, the sides prominent; app. sup. 
yellow, obtusely triangular; app. intermed. lying close together, 
broad, triangular, yellow, the superior margins blackish ; app. 
inf. scarcely evident, margined with long blackish hairs. In the 
female there is a broad obtusely rounded lamina proceeding from 
the upper margin of the last segment, on each side of which is 
a long finger-shaped appendage, from beneath which arises a 
straight deeply cleft tubular piece; the lateral valves are short 
and broad, almost truncated. 
Expanse of fore-wings 12—14 lines. 
Not acommon species. The recorded localities are the New 
Forest, neighbourhood of London, and Scotland ; I possess it also 
from the fens of Norfolk and from Torquay. 
I have considerable doubt as to the propriety of retaining 
Curtis’ name for this species. In his collection this and L, 
griseus were both present under the name of bipunctatus, and his 
description offers no very evident proof which species he had 
before him when writing it.
