The male has eyes prominent; metopidium perpendicular and tuberculose; 
furnished with two longish suprahumerals, followed on the back by a pair of much 
smaller spines. 
Pronotum entirely black, ending backwards with a knob, from which proceeds 
one long curved central horn, with a shorter horn on each side. A greyish green 
patch over each tegminal insertion. Abdomen large, bright orange, and ringed, each 
segment edged with a white border. The last abdominal segment deep black. 
Tegmina hyaline and shining with a broad brown transverse fascia ; limbus broad ; 
all the horns and the pronotum are very hirsute ; legs yellow, with black tibial tips.

CYPHONIA TRIFIDA, var. 
(Plate XXXIII. fig. 4, $ .) 
This species is liable to variation in size and coloration. Thus the figure I 
append has no conspicuous grey patch above the tegmina, and the abdominal apex is 
banded with brown. The fuscous bands on the tegmina are distinct. The male 
parts are shown at 3b. 
Expanse, 16 x 7 mm.

CYPHONIA CLAYATA, Fab. 
(Plate XXXIII. fig. 5.) 
Membracis clavata, Fab. M. bulbifera, Germ. Stoll. Cig. p. 82, T. 21, fig. 115. Combophora 
clavata, Germ. Fairm. l.c. p. 503. Fowl. l.c. Tab. VII. fig. 2, p. 00. 
Fairmaire says of this insect, “Nigra, abdomine pedibusque flavis; spinis posticis 
lateralibus medio inflatis, teretibus rufis apice deflexis,” which fairly agrees with 
my figure. Stoll’s figure and that of Fowler represent the body hirsute which my 
figure does not. The lower margin of the tegmina shows the edges dark, linear and 
curved, the specimen here drawn is from the B.M. Collection. Probably it is a male.
