a narrowly ovate transverse depression ; face with a longitudinal 

 groove running down the middle ; antennse half the length of 

 the body, black. Thorax more than twice as broad as long; 

 sides nearly straight and parallel, subsinuate behind their middle, 

 rounded and narrowed in front, anterior angles subacute, poste- 

 rior acute ; surface slightly convex, impressed here and there 

 with deep punctures, congregated in irregular rows; sides 

 thickened at their outer edge, broadly but obsoletely excavated 

 within, their surface covered with large, irregular, deeply-im- 

 pressed, confluent punctures. Scutellum semiovate, subacute. 

 Elytra broader than the thorax, subovate ; surface covered with 

 numerous irregular rows of deeply-impressed punctures ; inter- 

 spaces somewhat irregular, indistinctly wrinkled transversely on 

 the anterior half of the outer disk. 



This species is more coarsely and closely punctured than C. 

 Bonvouloirii ; the rows of punctures on the elytra are more nu- 

 merous, and the general surface of the latter is irregular. 



Genus Australica, Chevr. 

 Australica erudita. 



A. oblongo-ovata, convexa, flavo-fulva, nitida ; vertice, antennis ex- 

 trorsum, thoracis vittis duabus brevibus, infra apicem positis, 

 fasciaque basali, utrinque abbreviata, medio sinuata, scutello pe- 

 dibusque (femoribus anticis quatuor basi subtus exceptis) nigris ; 

 elytris punctato-striatis, nigro signatis ; pectore nigro-piceo.

Oblong-ovate, convex, shining flavo-fulvous ; the outer two- 

 thirds of the antennae, the vertex^ two short subapical vittse and 

 a narrow basal fascia on the thorax, the scutellum and legs (the 

 basal half of the under surface of the four anterior thighs ex- 

 cepted) black. Head broad and flat, minutely punctured; epi- 

 stome scarcely distinct from the face ; antennae slender. Thorax 

 three times as broad as long ; sides rounded and narrowed from 

 their base to their apex ; upper surface convex, finely punctured, 

 sides obsoletely excavated ; lateral margin rather more coarsely 

 punctured. Elytra broadly oblong, scarcely broader than the 

 base of the thorax, each elytron impressed with ten rows of 

 punctures, the first short ; interspaces very minutely punctured ; 

 the suture, a curved line which, commencing at the base on the 

 humeral callus, runs obliquely dbwnwards and inwards to the 

 lower edge of the basilar space, where it abruptly terminates at a 

 short distance from the suture, a narrow wedge-shaped patch on 

 the outer disk below the shoulder, placed parallel to the curved 

 line, and three longitudinal vittse on the hinder disk, the first 

 commencing .at the outer edge of the oblique line just before its
