216 Mr. G. R. Waterhouse's Notes 



I formerly met with this insect in the moat 

 round the palace at Fulham, and have recently 

 received specimens from Mr. Brewer, taken at 

 Covehithe, Suffolk. 

 13. Elongate : general colour golden aeneous, but 

 much hidden by an extremely short, and some- 

 what dense whitish pubescence : elytra each 

 ratiier rounded at the apex, scarcely truncate. — 

 D. hydrochceridifi, Fab., Gyll., Staph., Lacord. 



Specimens have been recently received by me 

 from Reigate, where it has been taken by Messrs. 

 Linnell and also by Mr. Brewer. 



Note. — In the four preceding species the 

 thighs are pale at the base, and the tibiae are 

 more or less pale in parts, but the greater por- 

 tion of each leg is dark, concolorous with the 

 body : the second and third joints of the antennas 

 are rather short — shortest in D. simplex and 

 least abbreviated in D. hydrochcerldis ; they have 

 the thorax densely rugulose and punctured, but 

 in D. hydrocha;ridis the sculpturing of this part 

 is exceedingly fine. In the following species 

 (No. 14) the legs are pale (i.e. rufo-testaceous), 

 and the third joint of the antennae is elongated, 

 and very nearly equal to the fourth. 



14. Elongate; golden-green, glossy; thorax very 



sparingly punctured and scarcely rugulose. — D. 

 Meiujanlh'idis, Fab., Gyll., Steph., Lacord. 

 II. Body convex; elytra, together, rounded at the apex; posterior 

 femora unidentate. ^ 



A. Legs concolorous with the body ; feet narrow. 



15. Above usually of one colour, but with this colour 



extremely variable, passing, in different indi- 

 vidaals, from golden-green to green, blue-green, 

 blue and black ; or to aeneous, cupreous and 

 purple. — D. sericea (^Leptura id.), Linn., lUig., 

 Gyll., Lacordaire : D. Proteus and D. micans, 

 Steph. 



Found in the London district, though spar- 

 ingly, according to my own experience : I have 

 recently taken it near Hammersmith, and in the 

 Plumstead marshes. Extremely abundant (for- 

 merly at least) in the Fens of Cam.bridgeshire.
