by having the third subcostal nervule of the forewing emitted beyond the end of the cell, 
and it differs from the first by the non-compressed and non-dilated tarsi, and from the second 
by the non-globosely incrassated tibial apices.”’ (Diéstant, 1. c., p. 207.) 
In the forewing of the type species the first subcostal nervule is given off much in the same 
position as in Gerydus ; the second subcostal in the male is given off at, instead of a little 
before, the end of the cell, in the female it is given off some little distance before the end, and 
the third subcostal is much shorter, and originates much nearer to the apex of the wing 
than it does in Gerydus ; the upper discoidal nervule originates from the subcostal nervure 
after the apex of the cell in the same extraordinary way as it does in Gerydus, but its origin 
isa little nearer to the cell. Other characters of neuration much as in Gerydus. The 
prehensores of the male are formed asin Gerydus, and that sex has no secondary sexual 
characters. 
The genus contains but three known species at present, which occur in Burma, the Malay 
Peninsula, Sumatra, Java,and Borneo. They are plain brown insects above, paler in the 
middle of the forewing in one species; underside white or greyish, thickly sprinkled with 
minute and larger-sized brown or ochreous dots and spots. PP. /fadius, Distant, from Northern 
Borneo differs from the other known species in having the upperside of the hindwing in the 
female “ with the posterior margin from anal angle to near lower subcostal nervule broadly 
greyish-white,”’ *

DESCRIPTION: “MALE. UPPERSIDE, both wings brown. Forewing with an oval 
longitudinal whitish spot in the middle. Aimdwing rounded and slightly angulated. 
UNDERSIDE, doth wings creamy-white, densely covered with undulating brown strige, with 
a darker brown dot between each vein near the exterior margin. FeMALe. UPPERSIDE, doth 
wings brown. Lorewing with but a faint indication of lighter colour inthe middle. Hindwing 
acute. UNDERSIDE, o/h wings as in the male.” (Moore, 1. c.) 
“* Paragerydus horsfieldi, and another allied species [P. ¢aras, Doherty] entirely black 
above, occur abundantly in Arakan and the Chittagong Hill Tracts, north of which they have 
not yet been observed. The egg is not quite so flat as in A//otinus multistrigatus, de Nicéville, 
and there is no trace of carination : it is beautifully reticulate above.” (Doherty, |. c.) 
I possess numerous specimens taken in Rangoon from May to August and again in 
December, one pair taken at Bhamo in Upper Burma in August; there are two females from 
the Chittagong Hill Tracts taken by the late Mr. H. M. Parish in November, also one from 
Perak, in the Indian Museum, Calcutta; and Mr. Distant records it from Penang, Sunjei Ujong, 
Malacca, and Singapore. It is evident from the dimensions given above that this species varies
