Head and thorax pitchy brown or shining black. 

 Prothorax paler. Abdomen oval, shining green, more 

 or less mottled. Cornicles brown and very small. 

 Legs green, and of moderate length. "Wings moderate, 

 and folded horizontally ; bronzed and highly iridescent. 

 Their apices rounded. Eyes and ocelli reddish and 

 fully developed. 



The colours of this insect are very inconstant. 

 Koch describes and figures two marked varieties, one 

 brown, with yellowish legs, the other with a vermilion- 

 red prothorax and abdomen. The rostrum is long 

 and reaches beyond the first body-ring. 



The sexes of this species are minute. They occur 

 late in the year, and are most plentiful during Novem- 

 ber and December. The male is apterous, and about 

 two-thirds the size of the female. Doubtless from its 

 smallness it was long overlooked or disregarded. 



Both sexes are distinctly rostrated at their early 

 stages, but possibly they lose these organs at a subse- 

 quent moult, since the Continental specimens are 

 described as mouthless. All the males under my 

 observation have been apterous, like the oviparous 

 females.
