It is found in salt marshes and on the banks of tidal rivers : 

 shores of the Thames below Gravesend ; Southend; Whitstable 

 and Herne Bay; Lymington Salterns; near Sandown Castle, Deal; 

 shores of the Humber, &c. ; also on " Portrain sands and Holy- 

 wood shore in Ireland/' A. H. Holiday. 



5. D. obscurus : obscure emeus vel nigro-virescens, thorace sub- 



globoso, elytris ovatis, profunde striatis, striis impunctatis, 

 tibiis anticis extus acute bidenticulatis. 



Clivina obscura, Gyll. Ins. Suec. 4. 456. Putz. Mon. 16. 8. 



This species is smaller and narrower than salinus, and may be 

 recognized by its elongate and cylindric form, and more especially 

 by the deeply impressed strife on the elytra, entirely smooth and 

 impunctate; the anterior tibia? are armed externally with two 

 distinct teeth, of which the one at the extremity is as large as 

 the corresponding one in salinus ; it is black beneath and obscure 

 brassy or greenish black above, with the antennae and legs pitchy 

 red. Length If line. 



M. Putzeys informs us that M. Reiche possesses a specimen 

 which was captured in England, and that it is rather common on 

 the opposite coast at Ostend. I have never met with it among 

 our indigenous species, but take this opportunity of calling the 

 attention of my brother-entomologists to an insect which has 

 been secured in England by a foreign collector. Mr. Haliday, 

 however, informs me that he has captured it on the sandy shores 

 of Lough Neagh. 



6. D. impimctipennis : capite thoraceque rotundato nigro-ob- 



scuris, elytris piceo-castaneis, oblongo-ovatis, profunde 

 striatis, striis impunctatis, tibiis anticis extus obsoletissime 

 bidenticulatis. (PI. I. f. A.) 



Beneath black, head- and thorax obscure black, sometimes 

 pitchy ; elytra deep pitchy chestnut, sometimes seneous. Head 

 with an oblong depression behind the eyes, palpi and antenna? 

 rusty red, the base palest. Thorax obovate, truncate in front, 

 very slightly narrowed below the anterior angles, sides gradually 

 rounded, globose behind ; disk convex with an impressed central 

 line terminating in front in the usual transverse impression, 

 which latter is bordered by numerous longitudinal striae. Elytra 

 oblong-ovate, obliquely sloped in front towards the shoulders 

 which are elevated, the sides very moderately rounded, convex, 

 deeply striated, the striae deepest at the base next the suture, all the 

 striae impunctate, except that in an occasional example some
