Lathrobium Jansoni, Crotch, according to M. Fauvel, who has seen 

 the original type, is most decidedly only L. pallidum, of a rather darker 

 colour than usual ; variations in that respect being found on the con- 

 tinent. M. Fauvel does not, however, make any remark as to the 

 discrepancy in the length of the elytra. 



Lithocharis ruficollis, Crotch Cat. {tricolor, Marsh., Steph.), is L. 

 vicina, Brisout, 1859, according to M. Fauvel. 



Stenus annulatus, Crotch, is referred to S. aceris, Boisd. et Lac, by 

 M. Fauvel, who states that species to be erroneously considered as 

 identical with impresses, Germ (annulipes, Heer) . Tbey are given as 

 distinct by de Marseul (1866). M. Fauvel states that our S. impressus 

 is his pyrenceus, M.S. 



Homalium crassicorne, Matthews (of which the unique type has 

 been most kindly lent to me by that gentleman), is, in my opinion, 

 certainly a depauperised immature example of the rare O. salicis. In 

 this view I am corroborated by M. Fauvel. 



Homalium brevicome, Matthews, nee Er., is vile var., according to 

 M. Fauvel. 



Homalium GEACiiiicoEisrE, Fairm., Faune Ent. Fr, 642. I have long 

 had a single, highly-coloured (possibly immature) example of this species 

 set aside as new to our lists ; and I now possess typical specimens given 

 me by Dr. Power, who has recently taken several. It is closely allied 

 to vile. M. Fauvel has corroborated this species for me. 



OCHTHEBITJS PoWEM, U. sp. 



Elongato-ovatus, leviter convexus,Jere opacus, obscure ceneo-piceus, 

 pedibus fuscis, geniculis tarsis palpisque nigrescentibus ; proihorace sub- 

 transverso, antice valde dilatato, angulis anticis prominentibus, grosse 

 creberrimeque punctato, canalicula mediana, foveolis quatuor discalibus 

 (quarum duo basales, tnajores, insecto a posteriori viso, Trogophlceorum 

 thoracis signaturam simulant), sulcisque lateralibws (irregularibus, antice 

 prqfundius impressis foveolasque discales anticas invadentibus) insculpto ; 

 elytris "jiitidulis, setis brevissimis, albidis, sat evidenter striatis instructis, 

 creberrime fortiterque punctato-striatis,punctis primo visufere transversim 

 confluentibus. Long. corp. vise i lin. (Angl). 



I am unable to refer this well-marked little species satisfactorily 

 to any published description ; and M. C. Brisout de Barneville has re- 

 turned it as utterly unknown to him. 



A single example was originally taken in brackish water on the 

 south coast by Dr. Power in 1866 ; and it has recently been found in 

 some numbers by Drs. Sharpe and Crotch under similar conditions near 

 the Chesil Bank.
