MEMBRA CIDJE. 
The pronotal horn of the female in some cases measures as much as fifteen milli¬ 
metres in length. The dark longitudinal band on the tegmina will generally distin¬ 
guish this species, but this mark is not always present. A considerable series 
of the species may be formed, from which the varieties, dependent on small 
particulars may be studied.

Pronotum viewed from the back trapezoidal in form, with a sharp and thin 
procephalic horn, and with sharp but small suprahumeral processes. 
The colour is bright ochreous yellow, with the lower marginal edges bright red ; 
a shorter red streak also occurs on each side of the sharp dorsal carina; the surface 
is much punctured ; the pronotum leaves almost the whole of the tegmina un¬ 
covered, but it does not quite extend to the tips of the same ; wings clear hyaline ; 
by the profile view the procephalon appears flat, broad, and round at the top ; legs 
ochreous yellow. 
Dr. Goding places A. quadrivittata under the genus Platycotis, and adds as 
synonyms Hoplophora lineata, Fairm. ; and also .4. guttifera. Walk. 
The side view of this insect is very like Platycotis, but the procephalon is not so 
erect. I have not been able to compare the neuration of the tegmina, so as to fix 
the genus witli certainty. The wings were defective in the specimen figured in 
the plate.

ACONOPHORA VIRIDRLA. 
(Plate XXVII. fig. 8.)

Small ; colour pale yellow ; pronotum rather dusky yellow in front, and marked 
with several faint, dusky, transverse fasciae on the dorsum ; tegmina and wings 
delicate and hyaline ; legs pale. Doubtless the living insect takes a green shade, 
like many others of the group which appear yellow in our cabinets. The front view
