Lathrolium Jansoni, Crotcli, according to M. Fauvel, who has seen 
the original type, is most decidedlj'- only L. pallidum of a rather darken 
colour than usual ; variations in that respect being found on the con-.- 
tinent. M. Fauvel does not, however, make any remark as to tha 
discrepancy in the length of the elytra. 
LitliocJiaris rujicollis, 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.,byr 
M. Fauvel, who states that species to be erroneously considered as? 
identical with impressus, Germ. (annuUpes, Heer). They are given as 
distinct by de Marseul (1866). M. Fauvel states that our S. impressus 
is his jjj/rencetis, M.S. 
Somalium 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 brevicorne, Matthews, nee Er., is vile var., according to 
M. Fauvel. 
Homalium gracilicoene, 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. 
OCHTHEBIUS POWERI, U. sp. 
Elongato-ovatus, leviter convexus,Jere opaeus, obscure ceneo-piceus, 
pedibus fuscis, geniculis tarsis paJpisque nigrescentibus ; prothorace sub^ 
transversa, antice valde dilatato, angulis anticis prominentibus, grosse 
creberrimeque punctata, canalicula mediana, foveolis quatuor discalibus 
(quarum duo basales, majores, insecto a posteriori viso, Trogoplilceorum 
tJioracis signaturam simulant), sulcisque lateralibus (irregula)'idus, antice 
profundius impressis foveolasque discales anticas invadentibus) insculpto ; 
elytris nitidulis, setis brevissimis, albidis, sat evidenter striatis instructis, 
creberrime fortiterque punctato-striatis,punctis primo visujere transversim 
conjluentibus. Long. corp. vix f 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.
