196 Pliytophaga Malayana. 



48. Rhyparida brunnea, n. sp. 



Subelongata, parallela, brunnea, nitida ; antennis, pectore pedi- 

 biisqiie obscure fulvis ; femoribus et tibiis apice tarsisque 

 piceis ; tborace elytris eequilato, granuloso, disco tenuiter 

 subcrebre punctato ; elytris infra basin late transversim ex- 

 cavatis ; striis infra basin sat fortiter punctatis, punctis 

 pone medium minus distinctis, apicem versus fere deletis ; 

 spatio basilari paullo elevato, minus fortiter punctato; inter- 

 spatiis planis, nitidissimis ; femoribus subtus dente minute 

 armatis. 



Mas. — Tibiis anticis compresso-dilatatis. 



Long. 2^ lin. 



Hab. Batchian. 



Head granulose, very finely and remotely punctured, lower 

 portion of front impressed with a deep longitudinal groove ; epi- 

 stome longer than broad, scarcely separated from the front, the 

 apical sutures being ill defined, apical angle obtuse ; sides slightly 

 rounded, anterior border broadly concave-einarginate, angles of 

 the notch obtuse, not produced ; jaws black ; antennae slender, 

 equal to the body in length. Thorax twice as broad as long ; 

 sides rounded, slightly converging in front ; anterior angles obso- 

 lete, hinder armed with an obtuse tooth ; above moderately con- 

 veXj finely granulose, disk impressed with fine but distinct punc- 

 tures. Scutelkim longer than broad, its apex round. Elytra 

 subparallel, slightly flattened on the disk, swollen laterally just 

 within the outer margin, strongly and broadly excavated below 

 the basilar space, longitudinally sulcate within the humeral callus ; 

 basilar space slightly thickened ; striae somewhat strongly punc- 

 tured below the base, finely punctured on the basilar space and 

 behind the middle, nearly obsolete near the apex ; interspaces 

 plane. 



The anterior tibiae in the S are dilated as in the same sex in 

 R. tibialis (ante, p. 183). The larger size, the entirely different 

 sculpture of the elytra, and the difference in form of epistome, 

 will separate it from that species.
