266 CHRYSOMELIDjE. 



widened, flavous. Thorax nearly twice as broad as long, sides 

 rather strongly rounded at base, from thence nearly straight and 

 slightly obliquely narrowed towards apex ; surface deeply but 

 sparsely punctured, punctures partly confluent, forming small 

 smooth yellow tubercles. Scutellum finely punctured, with dark 

 margins. Elytra broad and flat, slightly wider than thorax, 

 extreme basal margin strongly carinate near scutellum ; surface 

 closely and irregularly punctured to middle, interstices rugose, 

 rugosities more strongly marked outwards, yellow on a dark 

 ground-colour ; two somewhat feeble costae between shoulders and 

 suture, another from shoulder to apex ; behind the middle more 

 numerous and strongly raised costae, about nine in number, all 

 flavous. Pygidiura finely punctured and pubescent, dark brown 

 margined with flavous. Legs with dark margins to femora and 

 tibiae, the latter curved.

This species is probably nothing but a darker variety of the 

 preceding one. Suffrian points out that the coloration is darker 

 and that the elytra have a transverse 

 curved flavous band at middle, in shape 

 of a ridge. All this agrees with several 

 specimens before me in the collection of 

 M. Clavareau. There are, however, speci- 

 mens intermediate, both in coloration and 

 sculpture, which may be referred to either 

 species. In one specimen the elytra are 

 entirely dark brown with a sutural patch 

 below scutellum. The thorax has a lateral 

 band (not mentioned by Suffrian) and 

 another brown spot at middle of base ; and 

 in the female (the only sex known to 

 Suffrian) the transverse elytral ridge is

 pcecilopterus. smaller individuals from the same locality, 



which are no doubt the males, are much 



paler, with the elytral ridge only indicated at the sides, and with 

 the costee at apex uniting in pairs, one costa at suture and one 

 near the margins, long but not extending to apex, with two short 

 costae between the others, the inner costa is the longest. Breast 

 and legs entirely flavous. Everything else as in P. rubiginosus.
