main transverse rows of tubercles, the one along hind margin regular, hind margin 
straight, angles narrowly })roduced as short triangular spines, lateral margin with 
subtriangular pale testaceous spots, and a row of impressed, small, round black 
spots submarginally (which are more or less obsolete in the females and the larvte), 
margins of the last two segments finely serrate. Supra-anal lamina transverse, 
hind margins rotundate, serrate, depressed medially, slightly emarginate. Cerci 
lanceolate, flat, rather obtuse, scarcely exceeding lamina, brown. Penultimate 
ventral segment of abdomen much excavated. Subgenital lamina short, flat, 
margin rounded, finely tubcrculate, deeply emarginate. Styles very short, scarcely 
visible from above.

The under side is pubescent, but not neaidy so much as in the typical adult 
male specimens. The antei'ior femora are similarly spined as the latter, but the 
intermediary and posterior ones possess besides 2—3 small spines each, which are 
absent in the adult males and (supposed) females, otherwise they are quite similar 
in structure, armature of tibite, the form of tarsi, etc. 
Female .—Similar to above, excepting being less scabrous, in addition to the 
points noted above. Angles of meso- and metanotum much less produced, lobes of 
elytra and wings absent. Pore femora spinose, tibise unarmed. Supra-anal lamina 
similar to that of male nymph, but larger and flatter, less scabrous, scarcely serrate. 
Cerci shorter ; subgenital lamina broad, sub-semicircular, entire, margin smooth.

Locality .—Palm Creek, McDonnell Range (two immature males, one adult 
female), Bagot’s Creek and Illamurta (one female each). One of the smaller larvje, 
presumably belong to the same species, from Alice Springs is almost glabrous ; the 
other, still younger, is quite villous, and from Palmer River. 
Section III.—MANTODEA. 
M icPomantis (?) sp. Fawn coloured. Head transverse, flat; eyes promin¬ 
ent, subconical. Antennte filiform, very slender, about as long as the prothorax.
