280 THE GENERA AND SPECIES OF AMYCTERID.E, 



another less deep near the base. The elytra are three times the 

 length of the thorax, and considerably broader, with three rows 

 of strong and rather acute tubercles on each elytron. Between 

 the suture and the first row of tubercles there are three rows of 

 coarse granulations, between the first and second row of tubercles, 

 and between the second and third tliere are two irregular rows 

 of still coarser granulations, while the sides are transversely 

 rugose and coarsely striato-punctate. My description is taken 

 from a female specimen. In the male the elytra are so much 

 narrower that the double and triple rows of granules cannot be 

 traced ; the apex also of each elytron is slightly dehiscent and 

 tuberculate. I find some specimens with only two rows of 

 granules on each side of the suture of the elytra ; they may 

 possibly belong to another species.

 Boisduval's description of this insect is not sufficient to dis- 

 tinguish it from any other species of the genus. In sculpture it 

 corresponds; in most particulars to the description I have given 

 of A. Marshami. The posterior tooth of the crest is more acute 

 and pointed backwards, and the tubercles generally are sharper 

 and more spinose. It differs besides in having the back densely 

 covered with silvery scales disposed in vittee on the head and 

 thorax, and in vittee and spots on the elytra. The scales on the 

 sides are fawn coloured. The elytra are separately mucronate. 



This species seems to have a wide range, particularly in the 

 Southern districts.
