covering all, or nearly all of it. Tegmina with five oblong apical areas. Costal area 
mostly punctured at the base. Suprahumerals often largely developed and broadly 
dilated at the tips. 
CENTROTYPUS FLEXUOSUS, Fab. 
(Plate LIY. fig. 1.) 
Centrotus Jlexuosus, Fairm. l.c. p. 516. C. cinchorago, Guier. 
Large. General colour steel-blue or blue-grey. Shining, much punctured. 
Pronotum produced behind into a long straight thorn, projecting beyond the abdomen. 
The anterior part expanded into two flattened and widely extended suprahumeral 
wing-like processes, somewhat of the form of a hammer-head. Abdomen fusiform, 
ringed, and free above the pronotum. Apex in the female furnished with large genital 
valves. Tegmina hyaline, and finely bordered with rich warm brown, leaving the 
two discoidal areas clear and transparent. Apical areas 4-5. Legs long and stout. 
This is a remarkable insect, and not infrequently met with. 
I have specimens from Java in which the suprahumerals are more pronounced, 
but these insects are not shining or glabrous, but dull brown, and the tegmina are 
redder in colour. 
The legs have a silvery pubescence, and are quite concealed under the body. 
This insect appears to be widely spread in India and eastwards. I have 
examples from Java and from Burma slightly differing in size, which, however, I do 
not consider distinct. 
Expanse of wing, 18 mm. 
Size, 10 x 6 mm. 
Habitat. —Perak, Silhet, Malacca. 
C. ancliorago is described as having the tegmina sub-vinaceous in colour. 
CENTROTYPUS ALATUS. 
(Plate LIV. figs. 2, 2a.) 
Suprahumerals very broad and dilated. Colour warm Vandyke brown, with 
shining corrugated ridges. Tegmina delicate and hyaline, but the apices are rather 
ochreous. Posterior horn long, quite as long as the tegmina. Frons hirsute and 
ferruginous. Legs slightly spatulate. 
Size, 11x4 mm. 
Habitat. —Perak.
