and converging to the anterior angles, the latter ob- 

 tuse: upper surtace transversely convex, sub-variolose- 

 punctate on the sides, more finely and remotely punctured 

 on the disc, a central space on the latter nearly free from 

 punctures ; lateral border reflexed. Elytra broader than 

 the thorax, narrowly sub-ovate, their apices conjointly 

 rounded, above finely punctate-striate, the puncturing 

 near the apex nearly obsolete, interspaces flat ; on the 

 outer disc below the shoulder is a broad but ill-defined 

 longitudinal groove. Knees indistinctly stained with 

 piceous. 



G. nigriceps may be at once known, from all similarly 

 coloured species, by its black head. 



(Sp. lie.) Oephaloleia truncatipennis. 



Elongata, parallela, dorso depressa, rufo-fulva, nitida, 

 antennis (basi excepta) nigris ; thorace transverse, re- 

 mote et subtenuiter punctate; elytris thorace paullo la- 

 tioribus, fere paraAlelis, apice truncatis, dorso depressis, 

 tenuiter punctato-striatis.

Antennge rather more than a third the length of the 

 body, black, the first three joints rufo-fulvous, third joint 

 slightly longer than the second. Thorax distinctly trans- 

 verse, sides strongly reflexed, straight and slightly con- 

 verging from the base nearly to the apex, thence quickly 

 rounded and converging to the antei-ior angles, the latter 

 obtuse ; above transversely convex, excavated on the 

 sides just within the reflexed lateral border ; remotely but 

 distinctly punctate, the punctures rather closer at the base 

 and sides. Elytra broader than the thorax, sides sub- 

 parallel, obliquely rounded and converging near the apex, 

 the latter broadly truncate ; upper surface broadly flat- 

 tened along the sature, sides obliquely excavated below 

 the humeral callus; finely punctate-striate, punctures 

 entirely obsolete near the o] ox of the elytra; the middle 

 third of the outer disc impressed near the outer border 

 with a broad ill-defined longitudinal fossa. 



The truncate apices of the elytra, together with the 

 obtuse anal segment in the ? (the only sex known to me), 

 without difficulty separate this species from its congeners.
