124 NORTHERN ZOOLOGY. 



have three discoidal subpunctured ones running from the base to nearly the apex ; between the ex- 

 ternal discoidal furrow and the margin is a series of punctures near the apex, representing what is 

 called the marginal furrow, and between the internal one and the suture are the traces of three 

 others, the first just discernible, drawn, but interruptedly, from the base to the apex ; the second 

 consisting of three or four punctures near the apex, and the third parallel with the suture, con- 

 sisting also of punctures, sometimes confluent, and extending from the apex not quite half the 

 length of the elytrum; the surface of the elytra is covered with minute punctures very lightly 

 impressed, so as not to be discoverable except under a good magnifier : the cubit or anterior tibia 

 is armed with three teeth, the last of which appears cleft from its being furnished at the apex with 

 two short truncated transparent bristles, the two other teeth have only one such bristle. 



This species, which belongs to Mr. Stephens' family, A. a. 2, 2 differs in its sculpture, from any 

 Hister at present known. Its aspect is that of H. unicolor, with which it likewise agrees in size, 

 and many other characters, but it belongs to the section with the sides of the prothorax two- 

 furrowed ; whereas, in H. unicolor, they have only one furrow ; the elytra likewise of H. Paykullii 

 are punctured, which in the species just mentioned are perfectly smooth, even when viewed under a 

 powerful magnifier.

DESCRIPTION. 



Body black, glossy, thickly punctured, the punctures on the upper-surface, being most conspi- 

 cuous. Head circumscribed ; antennae and palpi nearly of a mahogany colour ; mandibles longer 

 than the head ; nose slightly impressed : prothorax with two furrows at the lateral margin, both 

 nearly reaching the base, the inner one, as usual, when arrived at the anterior margin, with the 

 corresponding one on the other side forming one furrow surrounding the prothorax on three sides; 

 just above the scutellum is a punctiform impression : the elytra, including the submarginal one, have 

 seven distinct furrows, the two next the suture being anteriorly abbreviated and very short, especially 

 the first; from the base of the first, or external discoidal one, an obsolete furrow runs obliquely 

 towards the submarginal one ; the four discoidal entire furrows when arrived near the apex of the 

 elytra are bent towards the suture: cubit piceous, armed with five teeth, the three outer ones obtuse.
