There are upwards of thirty specimens of this species in 

 the Museum — sixteen from the Falklands and the rest from 

 various places in Tierra del Fuego or Chile. It is separable 

 from the commoner A. nitida, Guer., as here interpreted, by 

 the narrower, subquadrate prothorax, the sides of which are 

 distinctly sinuate before the base and the hind angles sub- 

 rectangular, the less parallel, posteriorly widened elytra, with 

 their apices more produced and more deeply sinuate exter- 

 nally, the paler ti bias and tarsi, &c. The general coloration 

 is much more uniform in the two sexes — green, bluish green, 

 or obscure violaceous, no cupreous or brassy examples 

 occurring in the series before me. The male has joints 1-3 

 of the anterior tarsi less dilated, and tiie intermediate tibiae 

 less sinuate, than in the same sex of A. nitida. The antenna) 

 and legs are similarly coloured, and the prosternal process 

 margined laterally, in the two forms. A. annulicornis, 

 Curtis, type $ , from Port Famine &c, Straits of Magellan, 

 is a closely allied, more obscurely coloured insect. The
