setaB are not long, it is distinctly emarginate laterally from the median 

 to the basal part, grooved longitudinally in the middle, and completely

 tudinal band of light buff scales on each side of the median groove, 

 and another above the outer margin ; scutellum covered with white, 

 slightly elongate scales ; elytra elongate, deeply sinuate laterally, and 

 attenuate towards the apex, bi-costate on each side, covei'ed with 

 contiguous round white scales changing to light buff on the two 

 costae ; the scales on the pygidial part, abdomen, and pectus are pure 

 white and very dense ; the anterior tibia3 are bi-dentate outwardly, 

 the hind femora and legs are very long, slender, and simple, the hind 

 tarsi are slightly longer than the tibiae, and the hind claw is double, 

 the inner claw being less than half the length of the outer, which is 

 cleft laterally ; claws of the intermediate legs shaped as that of the 

 posterior legs, but having in addition a strong sub-horizontal tooth 

 under the robust outer one.

This insect will be easily identified, not only by the slender facies, 

 the nearly truncate cl^^peus, and the long, slender legs, but also by

 double instead of being simple. 



MONOCHELUS L^TUS, n. SpCC. 



Male : Head and prothorax black, elytra and legs light brownish red ; 

 the head and prothorax are covered with minute, nearly contiguous 

 flavescent scales leaving a narrow longitudinal band on each side of 

 the deep median groove partly denuded, and also a similar but 

 shorter space midway between the first discoidal space and the outer 

 margin ; elytra densely scaly but with three narrow denuded bands, 

 the two outer of which reach from base to apex, but the first dorsal 

 one reaches only to about the median part, these scales are whiter 

 than those on the prothorax and larger, and the denuded bands are 

 not always very well defined ; pygidium non-squamose, edge of pro- 

 pygidium, abdomen, and pectus very densely scaly; head i*ugose, a 

 little attenuate laterally towards the apex, which is slightly sinuate, 

 but the outer angles of which are rounded ; the prothorax is attenuate 

 laterally in the anterior part, rugose, and has a deep, median groove 

 reaching from base to apex ; elytra attenuate laterally towards the 

 apex, non-costulate ; pygidium convex, aciculate, moderately shining ;
