between each row there is a line of somewhat distant granu- 

 hitions. Lines of silvery scales are apparent on the medial line 

 and sides of the head and thorax, while on the elytra, the basal 

 two-thirds of the suture, almost the whole of the space between 

 the first and second row of tubercles, and the basal portion of 

 the space between the second and third series of tubercles, with 

 numerous round spots on the sides and apex, are similarly 

 marked.

 This species is the most common, and was the first described 

 of the genus. It is of a dull black, covered all over with minute 

 lighter coloured scales. There is an obtuse tubercle on each side 

 near the apex of the rostrum, and behind, near each eye, there are 

 two connate obtuse tubercles, of which the posterior one is the 

 largest ; there are also two minute tubercles on the forehead. 

 The thorax has a row of fiv^fe or six obtuse tubercles on each side 

 of the medial line, and at each side there are two large obtuse 

 tubercles ; the first, the largest, is bidentate and is situated a little 

 before the middle ; the other is situated behind the middle, and 

 is tridentate, the anterior and postei-ior teeth being very minute. 

 There is a very deep transverse impression near the apex, and
