of England. Mr. Ingpen has a specimen which he is informed was 

 taken at Cohiey-hatch wood, near London, 



X Sp. 2. Cerdo. Ohlongus niger, elytris concoloribus muticis, thorace transversim 



rugoso glabra, utrinque spinoso. (Long. corp. 1 unc. 4 — 5 lin.) 

 Ce. Cerdo. Fabricius.—Steph. Caial. 196. No. 2018 note. 



Oblong, glossy, black : head rugulose, punctate : thorax rugulose, the wrinkles 

 somewhat regular and placed transversely, the lateral margins each with a 

 short spine : elytra very rugose, especially anteriorly, concolorous, the apex a 

 little acuminated, unarmed. 



I have seen examples of this insect, which have been taken in 

 the vicinity of the metropolis ; but whether it be a truly indigenous 

 species is questionable. 



Genus CCCLXVII. — Cerambyx, Auctorum. 



Palpi with the terminal joint elongate-obconic j maxillary shorter than the 

 labial. Antennae longer than the body in the males, shorter in the females ; 

 basal joint very robust; second minute; remainder elongate, gradually de- 

 creasing in bulk to the apex, which is very slender and acute, the tip of each 

 joint incrassate : head oblong, nutant : eyes deeply notched : thorax rounded, 

 unequal, tuberculated, with a spine on each side: elytra elongate, depressed: 

 legs moderate : tibios compressed, all simple. 



This beautiful genus is well distinguished from the allied genera 

 by its depressed body, and its brilliant metallic (generally green) 

 hues ; peculiarities which seem to obtain throughout the numerous 

 exotic species contained therein : — the only indigenous species 

 is remarkable for the fragrant odour that it disseminates during its 

 living state, an odour which has been compared to Otto of Roses, 

 and that is retained for some considerable period after death ; it has 

 thence obtained the name of Mush Beetle^ though improperly, 

 the scent not resembling that of the drug whence its appellation is 

 derived. 



Sp. 1. Moschatus. Viridis, glaber, antennis cyaneis, elytris obsolete elevato- 



lineatis. (Long. corp. 1 unc. 1—6 lin.) 

 Ce. Moschatus. Linne.—Don. iii. pi. 9i.f. 2. Steph. Catal. 196. No. 2019, 



Shining green, glabrous : head a little punctured : thorax irregularly tubercu- 

 lated, the lateral margins with a stout spine : elytra sublinear, thickly rugulose.
