The cerci are of the ordinary slender conical form and do not reach so 
far as the end of the ovipositor. 
$. Smaller and slenderer with the cephalic horn and its crests, 
as has been already stated, reduced to a rudimentary condition and 
all folded or shrivelled up together soas to form a soft and flexible 
projection no more than about a millimetre in length. 
Organs of flight almost wholly membranous and hyaline. Tegmina 
with the marginal field semiopaque brown resolved into spots at the 
apex, with a few scattered groups of areolets in the discoidal area 
and the meshes of the anal gusset faintly smoky, and with some dark 
brown linear dashes on the longitudinal veins. Wings with their 
anterior margin pale brown spotted at the apex, the rest of these organs 
being very faintly iridescent-smoky, with obsolete double hyaline edgings 
to the transverse violets, from the base nearly to the outer margin, 
along which the smokiness and the longitudinal veins are alike darker, 
especially in the anterior area. 
In the Tenasserim specimen of this sex the cephalic protuberance 
is more broadly rounded at the top and less produced, and the horn 
is more rudimentary ( ? in consequence of the specimen being a dried 
one), but there is no other apparent difference between it and the spirit- 
specimen from Assam described above, except perhaps in the tint 
(exaggerated in fig. 1) of the wings, which is slightly deeper in the 
latter.

o nymph. Nearly allied to the preceding, which it closely resem- 
bles in the relative proportions of its parts and in every detail of colour 
and ornamentation, but from the same sex of which it differs in the 
possession of a fully developed cephalic horn and from the opposite sex
