tenth slightly increasing in width, eleventh about as long as 

 ninth and tenth combined and much wider. Palpi with two 

 spiniform processes on apical joint, one on the penultimate, 

 and two on the antepenultimate. A spiniform process also 

 on the cardo of the maxillae. Prothorax strongly and evenly 

 convex; punctures very minute. Elytra strongly convex; 

 with a deep stria on each from middle of base to middle of 

 disk, where it abruptly terminates ; punctures sparse and small. 

 Metasternum with a conspicuous oblique process on each side 

 of middle. Abdomen with apical segment encroached upon 

 by pygidium, this with a small fovea and "several feeble nodes. 

 Front legs with a spine on coxa and trochanter, femora rather 

 stout, tibiae thin and bisinuate; middle tibiae thin, the hind 

 ones thin and with a deep apical notch. Length 1*8-2 mm. 



9 . Differs in having somewhat shorter antennae, metas- 

 temum unarmed, under-surface of abdomen not encroached 

 upon by pygidium and legs somewhat shorter, with the front 

 tibiae no more sinuous than the middle ones, and the hind 

 ones not notched.

The processes on the metasternum are joined together at 

 the base, at the apex each is obtusely bifid, although the cleft 

 is very feeble on some specimens. From some directions the 

 terminal joint of the antennae of the male appears to be 

 regularly ovate, from others it is seen to be somewhat produced 

 on one side of the base. The figures of L. paljialis (2) will give 

 a good general idea of this remarkable insect, but it differs 

 from that species in being smaller, apical joint of antennae 

 paler than the preceding ones, and none black, armature of 

 the metasternum notched, front tibiae bisinuate and hind ones 

 notched. As on that species both sexes have the front coxae 

 and trochanters armed. The notched hind tibiae even more 

 clearly indicate the affinity of the genus with PalimboliK 

 (Didimoprora)) near which, despite the very different palpi, 

 it was referred from the only other known species by Raffray; 

 the spiniform process is so near the other part, however, that 

 the notch could be easily overlooked. Five specimens were 

 obtained by sieving fallen leaves at Malanda, of which one is 

 a female, 94 other specimens, all males, were obtained at 

 lights.
