566 Mr. J. Wood-Mason on Phyllothelys. 
6. Horn rudimentary. 
9. Horn well-developed, tapering very slightly and gradu- 
ally from its base to its truncated apex, which is divided by 
an angular notch into two points, with the edges of its folia- 
ceous expansions entire. 
$ ?. Axillary or plicate vein of tegmina 1-branched. 
Discoidal or anterior ulnar vein of wings 2-branched. 
Hab. Sibsagur and Cachar districts, Assam; Buxa, Bhu- 
tan; Upper Tenasserim ; and Mergui. 
2. Phyllothelys taprobane, n. sp. (Fig. 1, p. 368.) 
&. Unknown. 
2. Protuberance of vertex simple, without lateral lobes ; 
horn long-lanceolate, with its edges minutely notched, the 
teeth formed by the notches appearing to be the free ends of 
obscure branch-like thickenings which pass off from the 
primitive horn, as in the following species. 
Organs of flight of the same proportions and structure and 
of much the same colour as in the preceding, differing only 
in details; the tegmina having the space intervening between 
the radial veins and the dark mottling of the disk opaque, 
whity brown; the wings, their very bases, their anterior mar- 
gin from the base to rather beyond the middle, their longitu- 
dinal veins for varying distances from the base, and their 
transverse veinlets to within a short distance of the apex in 
both areas yellow or yellow-brown, the last-named being in 
addition very narrowly lined with hyaline on both sides. 
Axillary or plicate vein of tegmina 2-branched; discoidal or 
anterior ulnar vein of wings 1-branched. 
The legs differ only in matters of minufe detail from those 
of the preceding species ; owing to the dark marbling being 
more developed the yellow marks on the inside of the fore 
femora are smaller; the fore tibize are armed on the outside 
with 16 and 17 teeth and on the inside with 16 and 16; the 
free margins of the foliaceous lobes of the four posterior 
femora are minutely and decreasingly from the base denticu- 
late, with a single seta inserted in the distal side of each 
denticle. 
Total length, from apex of horn to apex of abdomen, 73 
millim.; height of head 17, of which the horn is 12°75; 
length of pronotum 27, of which the anterior and posterior 
lobes are respectively 5°75 and 21°25; length of tegmina 30, 
breadth 6°5; length of wings 26, breadth 14; length of 
abdomen 243 length of fore coxa 15, femur 16:5.
