XEW BRITISH SPECIES, ETC., IN 1865. 115 



extreme varieties are almost entirely black {Bothnicus, 

 Linn.), having often onh' the cordate mark upon the head 

 (Fig. 7), and these are the most common : the intermediate 

 specimens, chiefly males, have orange-coloured elytra with 

 transverse black bands, varying in extent in different indi- 

 viduals, and sometimes assuming a maculated form (Fig. 6).

( Chrysomela) ; C. O. Waterhouse, Ent. Monthly 

 Mag. vol. i. p. 278. 



Mr. Charles Waterhouse records the discovery by himself 

 of an example of this species among some British Coleoptera 

 belonging to Mr. Cocking of Norfolk, and which, as he is 

 informed, was found among some sweepings belonging to 

 Mr. Winter, captured by the latter, most piobably in the 

 Norfolk fens. G. affinh appears to resemble G. 1 0-punctata ; 

 but to be easily distinguished by its black thorax, which is 

 less contracted in front; and by the interstices of its elytra 

 being destitute of punctures. There seems to be a variety 

 with the tibiffi and sides of the thorax reddish.

A. Matthews, Ent. Monthly Mag. vol. i. p. 174. 



Mr. Matthews records the occurrence in England of this 

 species, formerly taken only in Ireland and on the Conti- 

 nent. It a])pears to be found on the sea-shore, as its name 

 suo^o^ests. 



From Mr. Matthews' remarks (Ice. cit. p. 247) it appears 

 that he is now convinced that the superficial sculpture of the 

 upper side, especially of the thorax, is the only safe diagnostic 

 character in the genus Trichoptei'tjx ; and it will be seen
