fusion, all over the country, in meadows, woods, waste and 

 cultivated lands. Both Dr. Power and Mr. Brewer have it 

 from gardens. 



I have already expressed my conviction that pusilla and 

 montana are specifically identical (having intermediate links); 

 and I shall not be surprised to find the present continental 

 notion of oleracea also included with them. It seems to 

 differ from pusilla very much in the same way as (or, in- 

 deed, in a lesser degree than) that insect does from montana. 

 I have examples from a marsh on Wimbledon Common, 

 which in their larger size and coarser punctuation would, 

 compared with pusilla^ seem to be oleracea proper ; but their 

 colour does not accord with that given by the authorities, 

 being: dark violet-blue instead of brilliant g:reen. These 

 would seem not difficult to connect with jyusilla. The ex- 

 tremes of the insect called O, montanay compared with types 

 of pusilltty are smaller, shorter, wider, with shorter and 

 stouter antennae and a rounder and less projecting humeral 

 callus to the elytra, which are scarcely perceptibly punctured ; 

 their colour also is dull dark blue. But there would seem to 

 be no limit to the powers of variation in the members of this 

 genus. I captured in September last, in Coombe Wood, 

 one specimen of an insect which should be in the oleracea 

 section, but which, from its very long and thin antennae and 

 legs, cannot be referred with any degree of certainty to any 

 species of which a description has been as yet published. I 

 feel sure that a judicious synthesis is much wanted in Grap- 

 todera, to say nothing of other genera.
