PLUME-MOTHS OF CEYLON. 
15 
Platyptilia citropleura, Meyr. 
T. E. S. 1907, 482. 
Distribution. —Maskeliya. Also found in Assam (Khasi Hills). 
Early Stages. —Early stages and food-plant unknown. 
Observation. —Quite distinct from taprobanes , being smaller and 
blacker ; moreover, the cleft in the forewing is so shallow that it 
does not reach to a position immediately over the outer scale-tuft 
on the hinder margin of the wing ; in taprobanes the base of the 
cleft is directly over this tuft. 
I have examined a specimen, taken at Maskeliya in June, in the 
collection of Mr. J. Pole, and two examples (both Maskeliya, Janu¬ 
ary, 1908), in that of Mr. G. B. de Mowbray and am further indebted 
to Mr. Pole for a specimen taken at Maskeliya in November, 1908, 
and which he has kindly added to my collection. 
HEPTALOBA, Wlsm. 
On its inception this genus was considered by Lord Walsingham as 
most nearly allied to Amblyptilia (Platyptilia), but the linear, 
similarly-shaped segments of the hind wing seem to me to place it 
much nearer to Oxyptilus. 
Plate B., figure B., shows the neuration of the only known species. 
It will be noted that vein 3 of the fore wing has apparently been 
rendered obsolete by the development of the cleft between veins 2 
and 4; at least, I have been unable to observe its presence after a 
careful examination of four specimens specially prepared for the 
microscope. 
The neuration of the hind wing (not shown in the figure) is as 
follows 1 b to apex of third segment ; 2 short, running into hinder 
margin of second segment near base ; 3 out of 4 at angle of cell, 
long, parallel, running into hinder margin of second segment at J ; 
4 to apex of second segment ; 5 and 6 apparently absent; 7 to apex 
of first segment ; 8 parallel to 7, running into costa at half. 
Heptaloba argyriodactyla, Wlk. 
Wlk., Cat. XXX., 929 ; Wlsm., E. M. M., 1885, 175 (fig.); Moore, 
Lep. Ceylon, III., 527, t. 209, f. 13 (unrecognizable). 
Distribution. —Kandy. Both species and genus are peculiar to 
Ceylon. 
Early Stages. —The life-history is quite unknown. 
Observation. —Easily distinguished from all other Ceylon plumes 
by the fissure of the fore wing into four segments. 
It was originally described by Francis Walker from specimens 
given to the British Museum by Dr. Templeton, but no exact locality 
is stated. I have seen examples from nowhere except Kandy, but 
in the immediate vicinity of that town it seems to be fairly common.
