 SchuuheiT seemed to regard this insect as a variety of A. 

 Marshami, and I have no doubt that varieties of A. Marshami 

 of smaller size than the original insect and with stronger tubercles 

 have been frequently takeu for the A. echidna of MacLeay, which 

 is in reality a very well marked and distinct species. 



The whole insect is of a deep black, very sparingly clothed 

 with cinereous scales and with the tubercles glossy. The head is 

 short and rather excavated between tlie eyes, with three tubercles 

 on each side, the one at the extremity of the rostrum less pro- 

 minent than in A. Marshami, the other two connate, with the 

 posterior one rather acute and pointing backwards. The 

 thorax has the medial line marked with several strise, with a row 

 on each side of five flattish tubercles diverging towai^ds the 

 middle, and with two larger tubercles on the sides, the anterior 

 bidentate. The thorax has also transverse impressions as in 

 A. Marshami. The elytra are not broader than the thorax, and 

 are almost parallel sided, with three rows of strong pointed 

 tubercles on each, and one row of granules on each side of the 

 suture, while the rest of the elytra are rugose and punctured, and, 

 near the sides, striated. The male has the apex of each elytron 

 very slightly mucronated.
