PHASMA (ACANTHODERA) SEMI-ARM ATA, WESXW.
Pliasmaaptera luteo-fusea, aijualida, subgraiiulosa, capite spinis diiabus inter ooulos, metanoto et abdommis segmeiitis
4 basilibus spina reflexa acuta in medio marginis postioi, femoribus omnibus lobia parvis angulatis instruotis.
Phasma wingless; of a dirty clay-bi'own colour, opaque and slightly granulose; the head armed with two small spines
between the eyes; the middle of the hind margin of the metanotum and four basal segments of the abdomen armed
with an acute reflexed spine (dilated at its base) ; all the femora furnished with small angular lobes.
Length of the body 2 inches.
Inhabits the Himalayan range. In my own Collection.
DESCRIPTION.-The head (fig. 1 a) is armed with two small spines. The aiitennie appear only to be
half the length of the body. The hind part of the tliorax (between the hind feet) and the base'of the
abdomen are dilated, the latter becoming gradually narrower to the sixth joint j the three terminal joints
are ovate, with a small erect lobe in the middle (fig. 1 a, the abdomen seen sideways); besides the lobes of
the femora, the tibiae possess several minute prominences. I am indebted to H. G. Harrington, Esq.,
for this species.

PHASMA (ACANTHODERA) BICORONATA. WESTW.
Phasma fusea spinis valde armata, capitis vertiee niedioipie mesonoti corona spinaruminsti'uctis; femoribus tibiisi|
ue lobis numerosis aeutis armatis.
Phasma of a rusty-brown colour, very much armed with spines (many of which arc compound, emitting smaller
spines at the base); the crown of the liead and the middle of the mesonotum are respectively furnished with a coronet
of strong spines, and the femora and tibi» are armed with numerous acute lobes.
Length of the body 2 inches.
Inhabits the I limalayan range. In my own Collection.
DissoiuPTioN.—This Ugly insect, with its strangely-spiued coating, recalls to mind some of the most
hideous of the reptile tribes. The antenuse are nearly as long as the body, with the articulations more
distinctly marlvcd than in the last species, the midcUe joints being considerably longer than the basal
ones. Besides tlio spines forming the two coronets (fig. 2 a, whcnce I have derived the specific name), the
abdomen has a double series down the back, as well as a row on each side.
The 7tli and 8th abdominal segments have an elevated tubercle in the middle of the back, and the
anal plate is very much angulated in the middle of its under side (fig. 2 h . )
I am also indebted to H. G. Harrington Esq., for this species.
