Cnemodon. 71 



italica. The larva is rough, light dirtily brownish with darker 

 longitudinal stiipes; it has almost parallel sides; the posterior spiracles 

 lie on a small process behind. There are two broods in the year; 

 the imago of the first occurs in April ; its larva is stated to devour 

 the egg-shell before it attacks the Goccids; it pupates and the second 

 brood appears in July or August, and lays eggs in September; its larva 

 or pupa hibernates. The pupa is drop-like and coloured as the larva. 



The species of Cnemodon are not well known and especially the 

 females are not well distinguished; the species occur in low herbage 

 in fens and woods, I have taken fulvimanus in this way in some 

 number in spring. 



Of the genus about three species are known from the palæarctic 

 region (after exclusion of morionellus) ; two have been found in Danmark.
