68 COLEOPTERA. 



should be erased from our lists; inasmuch as all its 

 exponents in collections in nowise agree with its published 

 descriptions, but are the T. nitidicollis of Stephens. There 

 appears to be some confusion about the latter insect ; as Mr. 

 Wollaston (Zool. 1855) states that specimens of it, taken by 

 himself in Ireland, and sent to Drs. Schaum and Kraatz, 

 were retui-ned as belonging- to a species unknown to them ; 

 and it is ranked as distinct under the name of nitidicollk, 

 Steph., in the last edition of De Marseul's Catalogue of the 

 Coleoptera of France. On the other hand, Mr. Sharp states 

 that Mr. G. R. Crotch told him he had recently submittted 

 a specimen of it to M. Ch. Brisout de Barneville, who 

 informed him that it was very close to, if distinct from, 

 2\ inijicollis. 



Mr. Sharp is also of opinion that this insect is merely a 

 variety of T. obtusus, differing in no respect from that 

 insect except in colour, the black bands at the base of the 

 elytra and apex of the abdomen being extended over a 

 greater area than usual ; and he states that, even in this 

 respect, intermediate grades occur in Scotland. 



Specimens in my own collection, taken by Mr. Zvlorris 

 Young, are decidedly only varieties of T. ubtuaus. 



T. ruficollis, from Erichson's description, appears to be of 

 the size of a large specimen of 2\ humerosus (to which he 

 likens it) ; and in every way a distinct species by its short, 

 convex build, large head, short and slender antennce, which 

 are entirely testaceous, and long thorax, which is but very 

 little narrowed in front. 



Dr. Kraatz (Ins. Deutschl. ii. 424, 8) places it next to 

 hunierofius, simply remarking that it is somewhat shorter and 

 more convex than ohtustis. 



The T. rvjicollh of Gyil. appears to be T. iransveisaUs.
