250 THE GENERA AND SPECIES OF AMYCTERID^, 



This species differs chiefly from S. Adelaidse in the shape of 

 the tubercles of the thorax, and from S. divaricatus in the 

 prolongation of the medial ridge of the rostrum to the vertex, and in 

 having the apex of the elytra less dehiscent and not mucronate. 

 It is also much smaller, and more of a cinnamon colour than the 

 last named insect. 



9. — SCLERORINUS EUGICOLLIS. 



Oblongo-ellipticus uiger fusco-squamosus, thorace rugoso- 

 tuberculato tuberculis antice valde clongatis, elytris seriatim 

 rude punctatis interstitiis 1 et 2 distanter 4 et 5 crebre 

 seriatim tuberculatis tuberculis squamulosis subconicis 

 setigeris apice dehiscentibus acutis. 



Long. 9 lin., lat. 4 lin,

This species is very like 8. vittatus, it differs from it in not 

 having white " vittse," in not having the medial line of the thorax, 

 in having the tubercles of the thorax more rugose and elougate, 

 and in having the apex of the elytra more acutely dehiscent.

 Amycterus sublineatus, Germ., Linn. Entom. vol. III., p. 217. 



" Oblongo-ellipticus niger fusco-squamosus, capite thorace 

 elytrisque griseo-sublineatis, thorace tuberculato lateribus 

 modice rotundato, elytris seriatim granulatis interstitiis 

 tuberculatis tuberculis disci raris obtusis lateralibus densis 

 acutis, abdomine subtus vitta maculari fusca." Germar.

The tubercles on the elytra are more numerous, and disposed 

 with less regularity in this species than in any of the preceding.
