52 COLEOPTERA. 



54. ToMicus FLAVus, Wilkin, Wat. Cat.; E. C. Rye, 



I.e. 

 The solitary exponent of this species (?) in the Stephensian 

 cabinet is only a large immature specimen of T. dryo- 

 graphus. Er. 



55. Phyllodecta cavifrons, Thorns., Skand. Col., viii, 



278; D. Sharp, Ent. M. Mag., vol. v, p. 100 

 {Phratora). 



Dr. Sharp notes that this species is probably not uncom- 

 mon. I find a single specimen of it among my short set of 

 vulgatissimaf accompanied by another which appears to oscil- 

 late betM-een the two species. 



Thomson's cavifrons is distinguished from vulgatissimaf 

 which it resembles in its blue colour and long antennae, by 

 the regularity of the striae of its elytra, the rounding of the 

 sides of its thorax in front of the middle, the wide exca- 

 vation of its forehead between the antennae, and (in the male) 

 the scarcely dilated basal joint of its tarsi, which is much 

 narrower than the third joint, and its uncurved posterior 

 tibiae. From vitellince, which it resembles in the even stria- 

 tion of its elytra, it may be known by its colour, more oblong 

 shape, longer antennae, frontal excavation, longer and less 

 transverse thorax, and the above mentioned character of 

 the scarcely dilated basal joint of the tarsi in its male. 



Thomson restores Kirby's name for the genus.
