268 THE GENERA AND SPECIES OF AMYCTEEID^, 



conical tubercles on each elytron. The first row is near the 

 suture, and commences with smallish tubercles a little way from 

 the base, and extends almost to the apex ; the second row is close 

 to the first, commences at the base, and stops short about a third 

 of its length from the apex ; the third row is at some distance 

 from the second, and extends the whole length of the elytra, and 

 has a slight change of direction in the middle. The sides are 

 striated and tuberculate, the tubercles being somewhat small and 

 hemispherical. The apex of the elytra is broadly rounded, with 

 six obtuse teeth or tubercles on the apical mai^gin of each elytron. 

 The ventral segments of the abdomen are punctured and longi- 

 tudinally wrinkled, the anal segment is slightly excavated, and 

 much punctured.

 Schonherr seems to have thought that this insect was iden- 

 tical with the Amycterus tuberculatus of Boisduval ; if it be, that 

 name has priority over that of Mr. Hope. The description, 

 however, given by Boisduval would apply to twenty species 

 of the sub-family. The rostrum and head are marked in this 

 species exactly as in the last, only the sculpture is less deep and 

 the lateral ridges are more convex between the eyes. The 

 thorax differs from that of A. Draco chiefly in the two rows of 

 dorsal tubercles consisting each of five tubercles mth sometimes 

 an additional one outside the line about the middle, and in 

 having a round mass of tubercles on each of the sides, instead 

 of the regular dentation of the other species, the round mass
