of the Species of the Genus Pachyrhynchus. 319 



round : near the apex of the elytra are four other large and oblong 

 spots, one on each side close to the outer margin, and one on each 

 side between these and the suture. The elytra are distinctly 

 punctured, and the punctures are disposed in striae.

In size and form this species very nearly resembles the P. mo- 

 nilifcrus. Rostrum separated from the head by a faint transverse 

 impression, with a longitudinally impressed line on the basal half, 

 and with the anterior half (which is moderately punctured) dis- 

 tinctly humped or raised above the plane of the posterior portion. 

 On the head are three spots of golden green scales, one on the 

 vertex, and one under each eye. Thorax but little swollen in the 

 middle, clothed with scales, with the exception of three large and 

 nearly square denuded patches, one on the fore part and two 

 behind ; these scaleless areas are separated from each other by 

 narrow interspaces in the form of a transverse band in the middle, 

 composed of green scales, and an oblong, nearly triangular, mark 

 in i\\e centre behind, which is formed of reddish scales. Elytra 

 ovate, convex (less dilated than in P. mon'diferus), punctate- 

 striated, and clothed with scales which have a pale copper-like 

 hue, exhibiting however but little metallic lustre ; not unfre- 

 quently they have a purplish tint, and always those which border 

 the denuded patches are more brilliant, assuming sometimes a 

 green and sometimes a golden hue ; immediately behind the scu- 

 tellum is a large round (but occasionally square) denuded area, 

 and rather behind the middle of the elytra is a transverse scaleless 

 mark extending nearly to the sides ; the anterior outline of this 

 mark or band forms a gently waved line, but the lower boundary 

 is more or less strongly dentated, it is most dilated in the middle 

 and most contracted by the encroaching of the scales at a short 

 distance on either side of the suture. A narrow black or scaleless
