26 ALURNUS.

Type in the collection of C. Sheppard, Esq. Var. A. in that of 

 J. 8. Baly ; Yar. C. in the British Museum ; Var. D. in the cabinet 

 of Major Parry. 



It is extremely doubtful whether this and the following insect 

 ought to be separated into distinct species. The only two specimens 

 that I have seen agreeing with Pertj's description are larger and 

 more deeply pimctui'ed than in A. corcdUmis ; they have the thorax 

 broader and less narrowed in front, and also the third joint of their 

 antemiaj is longer in proportion to the second. Var. C, a single 

 specimen of which is in the collection of Major Pariy, appears almost 

 inteiTuediate between the two ; in size and sculptm-ing it agrees with 

 A. coraUinus ; in length of antenna?, shape of thorax, and colouring 

 (sides of thorax excepted), with the present insect, as a variet}' of 

 which I have placed it ; on the other hand, some specimens of the 

 red variety of A. coraUinus are nearly as large, and as coarsely 

 punctured, as the typical fonn of A. thoniciciis. It would require a 

 much larger series of indi\dduals than I have before me, in order to 

 detcmiine the specific identity or differences of the two; I have 

 therefore thought it better for the present to leave them separate.

Guerin, although giving the reference to Vigors's paper, has by 

 some error changed the name coraUinus to coccineus.
