196 Longicornia Malayana. 



Brownish, with a greyish or ochreous-grey pubescence, com- 

 posed of very sliort regular and somewhat sca'e-like hairs ; head 

 rather narrow, the pubescence irregular and not scale-like ; pro- 

 thorax broader than the head, narrowed at the base, nearly equal 

 in length and breadth, somewhat coarsely and remotely punc- 

 tured, the disc with two greyish stripes, which are continuous 

 with two on the vertex ; scutellum subtriangular ; elytra elongate, 

 the stripes on the prothorax joining two shorter stripes or patches 

 at their base; body beneath, legs and antennae pale chesnut- 

 brown, with a delicate greyish pile; the antennae much longer than 

 the body (in one $ specimen half as long again). 



Length 3| — 4 lines. 



Rop'ica didijma. 

 R. fuscesccns, pube fusco-grisea tecta ; prothorace remote 

 punctato, vittis duabus griseis ; elytris subelongatis, ad hu- 

 meros fuscis, post medium maculis duabus albis oblongis 

 instructis. 

 Hah. — Bourn. 



Possibly a variety of R. servUis, but paler, the prothorax more 

 transverse, with the punctures, especially at the sides, fewer and 

 more remote ; the elytra shorter, with the scape smaller, less 

 cylindrical, and approaching to fusiform. 

 Length S\. lines.

Characteres ut in Ropica, sed antennce lineares, baud fimbriatcB. 



It is impossible to retain the species on which this genus is 

 founded in Rop'ica, without violating a character which is constant 

 throughout the latter group. The scape, variable in Ropica, is, 

 in the two species described below, shortly ovate, but the coloration 

 and apparent glabrosity (for the pubescence is visible only under 

 the microscope) give them quite a diftertnt habit. The punctures 

 on the ))rothorax and elytra are, as in other members of the sub- 

 family, furnished at the base each with a triangular scale-like hair. 



Meximia decolorata. (PI. X, fig. 2 ) 

 M. fulvo-testacea, fere glabra ; elytris postice subcallosis, cas- 



taneo-notatis ; antennis pedibusque albidis, castaneo-annu- 



latis.
