DYTISCIDiE. 
R^qimbart, M. Etude sur la Classification des Dytiscidee. Ann. Soc. 
Ent. Fr. (5) viii. pp. 447-466, pi. x. 
After deprecating the value usually attached to mere sexual differences, 
and especially the formation of the tarsi in the $ in this group, the 
author describes and figures the pieces of the meso- and meta-sternum, 
on which he is disposed to place greater reliance for purposes of classifi- 
cation, as being common to both sexes. He characterizes 5 sub-families 
or tribes, (1) Haliplince, with hind coxae covering the first abdominal seg- 
ments, and antennae 10-jointed ; (2) HygrobiincG (= Pelobiides), with 
head not received in the pronotum, of which the front margin is ciliated ; 
(3) Dytiscince (including Colymbetides), which, with No. 4, have triangular 
meso-thoracic epimera, the meta-thoracic episterna reaching the inter- 
mediate coxae by their inner angle, and the posterior coxal projections 
small, not lamellated, and more or less dilated at the apex, but which 
have 5 joints visible to all the tarsi ; (4) Hydroporince, with only 4 joints 
visible in the front and middle tarsi ; and (5) Noterince, with linear meso- 
thoracic epimera, the meta-thoracic episterna not reaching the middle 
coxae, and the posterior coxal projections wide, lamellar, and triangular. 
[Supposing these sternal characters to be admitted as dominant, the 
apparent difference in the tarsi should logically sink the Hydroporince as 
a sub-tribe of the Dytiscince^ of which they possess the major attributes.] 
Cnemidotus, Er., nee 111., which is simply Haliplus, is renamed Peltodytes 
(pp. 450 & 457) ; Eretes, Cast., is adopted for the preoccupied Eunectes, 
Er., and Metadema, Cast., for the undescribed Scutopterus, Esch. ; Agabus ? 
gaudichaudi,' is near Agabetes^ Crotch; Ilybiosoma, Crotch, evi- 
dently = Eriglenus, Thoms.
