76 COLEOPTEEA. 



elytra is (as in substriatus) distinctly wider than the rest. 

 Other characters of colour and punctuation mentioned by 

 Schaum are apparently not constant: but I observe that the 

 frontal rugosities in quadripunctatus are finer and more nu- 

 merous, the middle of the thorax is rather more produced 

 in front, and the scutellum is more triangular. Fairmaire 

 observes that there is sometimes another large accidental 

 puncture a little beneath the above-mentioned additional 

 puncture, but not always appearing on each elytron. 



I believe Dr. Power has on more than one occasion found 

 N. ^-jjunctatus in one particular locality, unaccompanied 

 by N. biguttatus.

 Found on the Banks of the Medway at Chatham, of the 

 Thames at Gravesend and Sheerness, and on other parts of 

 the south coast, especially in the Isle of Wight, and differing 

 from the inland fen-frequenting D. sigma, Rossi, in being 

 more robust, with shorter and stouter antennce, rather more 

 prominent eyes, a wider head and more transverse thoi-ax 

 (both of which are not so shining, being very minutely coria- 

 ceous), and wider and comparatively shorter elytra, of which 

 the sides are more rounded. The transverse indented fascia 

 on the elytra is wider, nearly always reaching more broadly 

 up the suture towards the scutellum, so as to leave a pale 

 humeral spot of less area, and invariably extending down-
