The head and thorax very coarsely punctured ; the abdomen more 

 delicately so, but more coarsely than in its congeners ; the abdo- 

 men very broad, and much rounded at its extremity ; the last 

 segment having a minute tooth on each side towards the base : 

 the vertex and dorsal portion of the pro- and mesothorax, with the 

 scutellum, of a rich coppery green, intermingled with red : the 

 face, legs, (excepting the tarsi, which are ficeous,) pectus, and meta- 

 thorax, of an intense blue : wings very fuscous, especially towards 

 their extremity : abdomen of a pinkish red, with a golden reful- 

 gence : the venter, black. (Length, 4 lines.) 



This splendid species, which has been taken three times at 

 Wandsworth, by my friend, W. W. Sanders, Esq. (to whose 

 liberality I am indebted for my specimen,) is the largest British 

 one I am acquainted with. There is a specimen in the British 

 Museum, but I am unacquainted with the place of its capture.

Head and thorax very coarsely punctured ; abdomen delicately so : 

 head, scape of the antennae, thorax, and legs, (excepting the 

 tarsi, which are piceous,) green or blue, occasionally splashed with 

 gold : the scutellum frequently golden : the wings hyaline ; the 

 apex with a broad fuscous band : the abdomen testaceous or 

 carneous, sometimes darker towards its apex, which is much 

 rounded, and it has occasionally a violet reflection. 



This very pretty insect, which I had the pleasure of intro- 

 ducing to the British Fauna, occurs in abundance at one 

 particular spot on Hampstead Heath, where I captured it 

 settling on the sand. I have for hours endeavoured to trace 

 its habits, but in vain ; all that I have been able to observe is, 

 that it alights on the ground, runs a few inches, turns round, 

 and flies off again. I have not been able to find whence it 

 comes, or whither it goes ; it may probably be parasitic upon 

 Tachytes pompiliformis, or Goryles tumidus, for I have
