60 Mr. R. M‘Lachlan’s Monograph of the 
black at the sides. Anterior wings broader and more rounded at the 
apex than in the three preceding species; brown, thickly sprinkled 
with small pale dots; the margins scarcely paler, the inner margin 
most so; a pale spot at the thyridium, and sometimes smaller 
ones at the base of some of the apical cells; varies in intensity of 
colour; neuration dark fuscous. Posterior wings subhyaline, 
the apex yellowish. Legs ochreous, with black spines. Abdo- 
men greyish-ochreous. In the male the upper margin of the 
Jast abdominal segment is produced in the middle into a broad 
lobe, which is bent under, densely scabrous and black (very simi- 
lar to that in the last species); app. sup. small, scarcely visible 
from above; app. intermed. short, triangular, slightly divergent, 
testaceous ; app. inf. prolonged upwards, broad and obtuse, 
yellowish ; penis-sheaths parallel, shining brown; penis very 
short, scarcely apparent. In the female there is a broad dorsal 
plate, with the apex produced and obtuse, and on each side of 
this an unequally-triangular acute lateral valve. 
Expanse of fore-wings 17—19 lines. 
A widely-distributed species, apparently not uncommon. The 
broad obtusely-rounded apex of the anterior wings, and their 
generally darker colour, will serve to separate it readily from 
the three preceding. 
The description in Ent. Ann. 1859, p. 93, 33, applies to pilosa, 
Pictet, which has not been found in this country. The present 
species is No. 6 (from the Righi) in Dr. Hagen’s Synopsis of 
Stenophylax in the Stett. Ent, Zeit. 1859, p. 133.

Antenne reddish-ochreous, annulated with brown. Head, 
palpi and thorax reddish-ochreous. Anterior wings short, much 
dilated and very obtuse at the apex, pale reddish-brown, pubes- 
cent, sprinkled with rather numerous small pale dots, especially 
towards the apex; the pale dot at the thyridium conspicuous ; 
neuration rather darker; first apical cell long, extending about 
one-third along the upper edge of the discoidal cell. Posterior 
wings subhyaline, tinged with brown. Legs ochreous, with black 
spines. Abdomen ochreous. In the male the upper margin of 
the last abdominal segment is produced in the middle into a broad 
triangular flap, which is bent down, but not scabrous or black ; 
app. sup. and intermed. hidden under the flap; app. inf. long, 
directed upwards, coming to a fine point at the apex.
