membranous lid, the spaces between the lids filled with a soft white froth- 
like substance, the whole series of cells being fastened together on each 
side by a strong layer of chitine. Each cell is ‘05 or ‘06 inch in 
breadth. 
After this great labour is completed, the female remains for some hours 
still as though thoroughly exhausted, her attenuated form shows to what 
an extent her bulk has been drawn upon to furnish material for the egg- 
cases. In a short time her vigour and appetite return, and she is again 
eagerly catching here living prey. After the lapse of a few days, her form 
again becomes distended, and she is ready for the formation of a fresh egg- 
mass. 
Five or six of these masses are usually made by one female of one pair 
under observation. The first egg-case was finished on 16th January, at 
5 a.m.; a second one was made on the 25th of the same month, at 
11.45 p.m. These structures soon lose their brilliancy, and become of a 
dull whitish colour, which gradually darkens to brown. They are often 
placed in an irregular group. ‘The female visits them and stands over them 
at times. In a warm room the young leave the egg-case in about fifty days 
after the eggs are deposited.

Specimens of the insect, whose habits are here described, were sent by 
me several years ago to Mr. Wood Mason, but I do not know if it has as 
yet received a name. The following diagnosis will be sufficient for recog- 
nition :— 
Animal green; the anterior coxe and costal vein of the wings yellowish: 
a bright blue spot on the anterior femora around the auditory organ. 
Head smooth, wider than the thorax. Prothorax keeled, with a groove on 
the keel anterior to the suture; rough. Wings of uniform texture. An- 
terior limbs with the cox finely denticulated on each side: lower margin 
of the femora with 15 teeth, alternately larger and smaller, on the inside, 
five longer ones on the outside, and four in the median line near the audi- 
tory organ, one of which is larger. Tibia with 12 teeth on the inside and 
11 smaller ones on the outside, increasing in length distally; the ba 
tooth very long and curved. 
Male.—Length, 1:15; of pronotum, ‘87; of elytra, 1:01 inch. 
Female, —Length, 1:2; of pronotum, ‘82; of elytra, 1:10 inch.
