Of shorter form than Pr. caudata ; the posterior discoidal 

 ridge of the elytra very largely developed, long, high, and 

 compressed, the disk between it and the short, almost conical, 

 basal crests appearing concave ; this part is clothed with a 

 whitish-ashy pile, the same colour forming a margin to the 

 scutellum and an indistinct patch on the posterior surface of 

 the thorax ; the colour of the rest of the body is blackish 

 brown. The sexual difference in the length of the antenna? 

 is well marked — the male having these organs a third longer 

 than the body, with joints 5-11 long, filiform, and subequal; 

 the female having them three fourths the length of the body, 

 and joints 5-11 much shortened. The antenniferous tubercles 

 are unusually elevated in this species, causing the concavity 

 of the vertex to be deeper and more triangular.

Many examples. Also Hong-Kong, China. 



Praonetha rigida^ n. sp. 



P.oblonga, atro-fusca, thoracis lineolis prope basin duabus, maculaque 

 utrinque elytrorum versus apicem triaugulari, laterali, albo-ochra- 

 ceis ; antennis brevibus, fusco et griseo annulatis ; elytris crista 

 centro-basali et carinis duabus posticis (iuteriore magis elevata), 

 apice brevissime oblique truncatis. Long. 3|-4^ lin.

Moderately elongated, convex ; dark brown, with numerous 

 lighter-brown spots, besides two distinct longitudinal pale 

 lines on the basal part of the disk of the thorax, and an irre- 

 gular triangular patch of the same colour on each side of the 

 elytra towards the apex. The antennas are much shorter than 

 the body in the two examples before me (female?), with joints 

 5-11 forming only one half of the total length. The thorax 

 is very coarsely punctured. The elytra are very convex and 

 laterally compressed (as in all the allied species), abruptly de- 

 clivous at the apex, with the apex itself briefly and obliquely 

 truncated. The ridges are not very elevated, the basal one 

 moderately elongated, and the posterior one much longer, with 

 an exterior raised line parallel to it ; there is also a third, 

 and shorter, raised line, exterior to the second, and a little 

 nearer the apex.
