a conical elevation near the base. Wings small, extending 

 to the middle of the basal segment of the abdomen ; fore 

 margin blackish ; hind area smoky, with dark veins. Legs 

 moderately long, the middle ones shorter and thicker than 

 the rest, blackish, varied with irregular luteous fasciae ; 

 fore femora with a small tooth near the apex beneath ; 

 middle femora with two acute lobes near the tip above, and 

 one beneath ; hind pair with a small spine near the apex 

 beneath ; all the tibiae slightly dilated near the base within. 

 Tarsi compressed, but not crested.

A female pupa, rather more than 3 inches long, has the 

 rudimental tegmina 1 J line long, and the rudimental wings 

 2 lines long. A male pupa, nearly 2J inches long, has 

 rudimental wing-covers 1 line long, and rudimental wings 

 4 lines long ; the latter similar to those of the insect repre- 

 sented in PL XXVII. fig. 4. The armature of the body 

 and legs is similar to that of the female, but the spines and 

 rugosities are less developed.

Elongated, subcylindrical, with the terminal segments of 

 the abdomen dilated. Head subquadrate, luteous ; hind 

 part darker, without ocelli or spines. Antennae nearly the 

 length of the body. Pro- and mesothorax armed with 

 numerous spines, the anterior ones directed obliquely for- 

 wards ; those of the prothorax forming two rows, those of 

 the mesothorax forming three, the central row running 

 along the dorsal central carina ; the sides and under part 

 also armed with smaller spines. Tegmina small, nearly 



rounded, brown, with a small pale spot near the inner mar- 

 gin. Wings about twice the length of the tegmina, and 

 extending to the middle of the first abdominal segment ; 

 costal area brown, with luteous shades ; hinder area dirty- 

 white, slightly tinged with pink and with several brownish 

 clouds. Abdomen long and unarmed. Operculum extend- 

 ing beyond the extremity of the abdomen, its apex slit ; 

 armed at the sides with two elongated horny appendages, 

 furcate at their tips, enclosing two elongated curved fila- 

 ments, as in several of the preceding species. Legs long 

 and simple (the two hind ones wanting in my unique spe- 

 cimen of the female).

This species is at once distinguished by its large size, the 

 disproportionate length of the mesothorax, and the very 

 small tegmina and wings. The head is nearly square, 

 rather flattened above, with the hinder margin raised into 

 four small elevations. The antennae are long and very 

 slender ; the basal joint flattened above ; they are uniform 

 brown. The mesothorax is very long and subcylindrical, 

 with the middle ridge but slightly indicated ; the surface is 

 marked with a number of minute acute granules placed 

 wide apart, of which also there is a row of about fifteen 

 along each lateral margin. The hind part is dilated at the 

 place of insertion of the middle legs, and on the upper side 

 are affixed the two minute scale-like black tegmina. The 

 metathorax is considerably wider than the mesothorax, with 

 the wings affixed at about one-fourth of its length from the 

 fore margin ; they are small, being about two-thirds of the 

 length of the metathorax ; they are rich rosy-coloured, with 

 seven or eight longitudinal black veins gradually widening
