Manners^ &t. of some of the British Bradtelytra, 117 



not quite certain of the correctness of my nomenclature, and as 

 in many cabinets the three are confounded under the common 

 name of ceneocephalus, I shall add short characters of ihem as 

 they are named in my own collection : 



St. chalcoccphalus : the broadest and stoutest of the three ; a 

 slightly raised concolorous shining line between the antennae ; 

 " head and thorax brassy, finely punctured, with very delicate 

 pubescence, the latter glossy, with two rows of larger impressions, 

 and four still larger on the lateral margin;" elytra red-brown, 

 with delicate brown pubescence ; abdomen clothed with a very 

 delicate imle brown pubescence, with darker dots and longitudinal 

 lines ; antennae dark rufous. 



St. cEnelcoUisI the narrowest of the three 5 antennse pitchy- 

 brown, inclining in some to ferruginous ; a raised brassy-yellow 

 line between the antennae ; head and thorax blackish brass, punc- 

 tured, with two irregular rows of somewhat larger punctures on 

 the thorax ; elytra deep pitchy ferruginous, paler at the suture 

 and margins ; abdomen clothed with a short close brown pubes- 

 cence, paler at the base of each segment, and with traces only of 

 pale longitudinal lines. 



St. ceneocephalus : shorter than the others, and intermediate in 

 width ; nearly uniform brassy-brown, pubescent, the abdomen 

 obscure. The St. sericeus of Marsham, under which name a pair 

 stand in Mr. Vigors's cabinet now in the possession of the 

 Zoological Society ; but one of these (a broken specimen) is, 

 unless I mistake, St. chalcocephalus. Each species, it should be 

 observed, has a narrow line down the middle of the thorax free 

 from punctures. 



My attention was first drawn to this subject by capturing at 

 Ryde, in August, 1835, what I supposed a remarkably high 

 coloured specimen of St. ceneocephalus, but which I found on 

 examination to agree closely with Mr. Stephens's description of 

 chalcocephalus : I considered this a great prize, as chalcocephalus 

 was then marked f in the " Illustrations," but shortly after I picked 

 up another in the streets of Bath, and on re-examining numerous 

 Cornish specimens then standing in my cabinet as ceneocephalus, 

 they all proved to belong to either chalcocephalus or ceneicollis ? ; 

 while on my subsequent visit to the Scilly Isles, I was unable to 

 detect either of those species, though what I consider the true 

 ceneocephalus abounded in all parts of the group. All my speci- 

 mens of ceneicollis 1 are Cornish, but I have been shown several 

 taken near Oxford : chalcocephalus appears to be found throughout
