74 COLEOPTERA. 



It appears to differ from A. moesta, according; to Ericlison, 

 in having the thorax and abdomen, towards the apex, some- 

 what narrowed, and in the abdomen being more thickly 

 punctured. 



It differs from A. lanuginosa in the somewhat depressed 

 pubescence, and in having the elytra thickly and less strongly 

 punctured.

 This species was originally determined by Dr. Power, and 

 taken by him near Mickleham. It comes next after con- 

 st7'icta, Er. ; the abdomen being, however, not quite so con- 

 tracted at the base as in that species, and it is smaller, duller, 

 not so dark, and inclined to a blueish tint.

 I am informed this species was originally determined by 

 Mr. Janson ; it was taken at Burford Bridge, near Mickle- 

 ham, on the banks of the river Mole, by Messrs. Janson and 

 Brewer, and by Dr. Power, Avho has also found it on the 

 banks of the Thames at Halliford. It may be distinguished 

 from T. leucopa by its generally lighter colour and lesser 

 bulk ; also by its I'ufescent antennae and legs. Its place is 

 next after T. leucopa.
