Very closely allied to A. latipennis, but larger and broader, and 

 readily distinguished by the very large size of the tubercles on the 

 elytra, and the greater development of the sculpture both of the 

 upper and under surfaces. 



Both A. latipennis and A. siibornatus vary a little in 

 their sculpture, especially that of the thorax ; but, having 

 examined a considerable number of examples from 

 various localities, I have little doubt of the two being 

 distinct species. 



Found at Sapporo and Junsai, on "a low plant," in the 

 island of Yeso, and likewise inhabits East Siberia, as I 

 have a pair from Amurland in my own collection, and 

 there is an example in our national collection from 

 Siberia, labelled latipennis by Jekel. A. latipennis is 

 recorded in the catalogues of Siberian Coleoptera, but it 

 is probably in error for the present species, as it now 

 appears probable that A. latipennis is a more southern 

 insect. 



Faust, in his paper on Siberian Curculionidse, in 

 Deutsche Ent. Z., xxvi., speaks (p. 295) of A. latipennis, 

 Jek., with which he says A. flainman us, Motsch. (Schrenck, 

 Amur Keise, p. 171) is identical. I have no means of 

 knowing whether Faust referred — as appears probable — 

 to the species I am now discussing ; but Motschoulsky's 

 few remarks do not amount to a description, and do not 

 apply very well to this species, as he says nothing about 

 the dense punctuation of the anterior parts of the wing- 

 cases and other peculiarities.

This remarkable species is very variable in colour, no 

 two specimens being quite alike, and the upper surface 

 in extreme specimens has the yellow marks so reduced 

 that it may be described as quite black. The sculpture 

 varies but little, and I entertain no doubt as to the 

 correctness of the above synonymy. 



Bare ; but occurs on the main island, and on Yezo. 

 Yokosuka, Miyanoshita, Junsai, and Sapporo.
