rowed in front, dilated and rounded at the sides, and the latter 

 crenulated before the middle ; the elytra very shining, profoundly 

 punctate- sulcate, the intervals between the punctures narrow and 

 distinctly elevated, the interstices of the sulci narrow, convex, 

 nearly smooth or very finely rugose transversely. (Length 2 — Sp- 

 lines.) Gyllenhal justly observes, that it varies greatly in magni- 

 tude ; it also varies in having the sides of the thorax more or less 

 dilated and rounded in the middle. Mr. Waterhouse has a fine 

 male specimen (3^ lines) that has the thorax subglobose, with 

 the sides remarkably dilated and rounded. I have a very small 

 female specimen that only measures two lines in length, and has 

 the thorax less rounded at the sides in proportion. The insect 

 preserved in the Linnsean museum, which is pinned to the name 

 carbonariuSj agrees so well with the short description of Linnaeus, 

 that I have no doubt of its authenticity ; it is a large female (3|^ 

 lines), and the insect placed near to the label, but not upon it, is 

 certainly a small male (2 lines) of the same species ; these insects 

 agree so very closely in every character with GyllenhaPs descrip- 

 tions of Rhynch. carbonarius ( ? ) which he refers to Linnseus, and 

 R. atratus {S)> that there can be no doubt of their identity. 

 Mr. Curtis has figured with his usual accuracy the female, and 

 the head and rostrum of the male ; I have frequently inspected 

 the two insects in his cabinet, and I am now satisfied they are 

 correctly referred by him to Cure, carbonarius of Linnseus, al- 

 though at one period, from the variable form of the sides of the 

 thorax and their small sides, I was a little dubious. Germar has 

 incorrectly referred this insect to Cure, atramentatius of Mar- 

 sham* ; Gyllenhal in his 4th volume, in accordance with the opi- 

 nions of Schonherr and Germar, has adopted that name, and 

 cited carbonarius of Linnseus as synonymous ; Schonherr in his 

 Supplement (vii. p. 140) still adheres to the Marshamian name, 

 and there refers it to Germar !, notwithstanding he had pre- 

 viously received specimens from me (as will be seen below) of the 

 true Cure, atramentarius of Marsham and Kirby. Cure, carbo- 

 narius of Fab. (Mus. Fab.) is referred with doubt by Germar to 

 Linnseus ; it is elaborately and well described by Professor C. H. 

 Boheman in the work of Schonherr under the name of Magda- 

 Unus carbonarius of Fabr., a name that must necessarily be 

 changed. I possess an insect given to me by Mr. Bracey Clark 

 (which he found upon the fir, Pinus sylvestris, at the sides of the 

 Jura mountains in Switzerland) that agrees exactly with the de- 

 scription by Boheman of Cure, cai^bonarius of Fab. 



Only seven specimens of this insect have come under my ob- 

 servation : two in the collection of Mr. Curtis, taken by him from 

 a hazel-tree near Ambleside the 19th of June ; one in each of the
