P/iyhrphaga 31alayana. 131 



together with its fellow forms an angle on the suture, remains in all 

 the individuals I have hitherto seen without change, but the anterior 

 patch occasionally varies very considerably ; in some specimens 

 it unites at the suture, and sends a narrow line upwards to the 

 scutellum ; in others, as Var. C, it is not produced posteriorly, 

 the hinder border fonning a transverse straight line, whilst an- 

 teriorly it extends upwards to the base, entirely covering the 

 shoulder ; in Var. D it becomes smaller and irregularly cruciform.

Front very coarsely rugose-punctate, its lower edge continuous 

 ■with the encarpse and apex of epistome; surface of eiicarpae irre- 

 gular, impressed with several large punctures ; epistome wedge- 

 shaped, more finely punctured than the front ; on either side, just 

 above its apex, is a large deep irregular fovea ; antennae more 

 than half the length of the body, six outer joints broadly dilated, 

 the sixth to the ninth gradually increasing in width, apex of apical 

 joint obtusely angulate, extreme apex truncate, the fourth and fifth 

 joints compressed, the latter equal in length to the sixth, narrowly 

 dilated from base to apex. Thorax scarcely longer than broad at 

 the base, subconic, sides slightly rounded and converging from 

 base to apex, hinder angles acute ; surface deeply and remotely 

 punctured. Elytra narrowly oblong or oblong, parallel, convex, 

 distinctly excavated below the basilar space ; humeral callus 

 moderately prominent, bounded within by a longitudinal ex- 

 cavation ; surface somewhat finely but deeply punctured, the 

 punctures closely arranged in numerous longitudinal rows. 



Very nearly allied to C. peregrinus (p. 1 32) ; it differs externally 

 slightly in colour, most of the specimens being of a greenish blue, in- 

 dividuals without any green tint being apparently rare. The thorax 

 is more distantly punctured, and the fifth joint of the antennae,
