band on each side. This variety has been recorded 

 for Britain, but, I believe, on unreliable authority. 



Var. viresccns, Moq.: animal greenish, black bands. 

 French. 



Var. aurea, Lessona and Pollonera : animal white, 

 back yellowish, mantle white, foot-margin yellowish 

 gold ; bands of back and mantle obsolete. Italian.

 rossa in Piemonte." — Lessona and Pollonera. See 

 Bibliography.) 



Var. nemoralis, Dumont and Mortillet : animal of 

 pale colour, with the sides scarcely coloured, with 

 the mantle often of a lighter colour than the back. 



I first noticed it upon this coast in 1882, when I 

 took three or four specimens in St. Clements Bay. 

 I sent these to various friends for identification, but 

 without result. 



In 1884, while collecting in the same locality with 

 Dr. Kcehler (of the Faculte des Sciences, Nancy), I 

 called his attention to a specimen, which he at once 

 recognised from the description of Signoret as the 

 insect recorded from Rhe, and named sEpophilus 

 Bon?iairei. 



We were fortunate in obtaining about a dozen 

 specimens in that one tide ; Dr. Kcehler was thus 

 enabled to make some observations on its anatomy

French. Locard found this variety in Savoy and 

 Haute-Savoie. 



Var. alpestris, Dumont and Mortillet : animal of a 

 very deep colour, so that the bands on the mantle are 

 not discernible. This was also found by Locard in 

 Savoy and Haute-Savoie.

A MARINE HEMIPTEROUS INSECT. 



THIS marine, or rather submarine, insect, which 

 appears to have escaped the attention of 

 English naturalists, is not uncommon on the coast of 

 Jersey. Hitherto it has been recorded in one instance 

 only (1879), as taken in the Isle of Rhe, in the Bay of 

 Biscay, and described by Signoret in, I believe, the 

 transactions of the Paris Academy of Science.

which are very interesting, and have now appeared 

 in his " Recherches sur la Faune narine des lies 

 Anglo-Normandes." 



The following is a description of the insect : 

 Length, one-sixth of an inch ; breadth, one-twelfth ; 

 colour, deep reddish-brown ; body, limbs, and 

 antennas closely covered with fine silky hairs of a 

 yellowish tint ; eyes which are compound and very 

 brilliant, ruby-red ; wings, the horny portion (it 

 must no doubt be classed with the Heteroptera) 

 alone developed. It lives under stones which are 

 rather deeply set in the loose gravel, in proximity to 

 rocks. That it is unquestionably marine is shown 

 by the fact, that it is invariably found in company 

 with such animals as Nereis, Phascolosoma, Astemma, 

 and Gammarus. Upon some of these it no doubt de- 

 pends for its subsistence. It is a nimble little insect, 

 running with great rapidity, and, among the bits of
