114 COLEOPTERA. 



Helophorus Mulsanti, Rye, Cat. ** British Beetles." 

 Crotch, Cat. Brit. Col. ed. 2. 

 dorsaliSf Muls., nee Marsham. 

 The imposition of this name to the insect taken by Messrs. 

 Crotch and Archer near Liverpool appears necessary. 



Helophorus oranularis, Linn. 

 Under this name Mr. Crotch (loc. cit.) connects the insects 

 known to us as gramdaris, griseus, and obscurus, Muls. 

 {(vneipennis, Thorns.), admitting his inability to define them, 

 without the addition of three or four more species, to which 

 latter alternative he inclines. 



Hydr^na flavipes, Steph. 

 Mr. Ciotch (loc. cit.) states that this species was described 

 by Mr. Waterhouse as atricapillus, but was leferred to a 

 new genus of which the characters were incorrectly exposed ; 

 hence his name cannot be retained. This is not exactly true. 

 The characters (chiefly the comparatively small palpi) were 

 correctly exposed, but were afterwards not considered suf- 

 ficient to establish a new genus. There appears to me to be 

 no reason whatever for proposing to drop Mr. Waterhouse's 

 name for the species. 



Hydr^na Sieboldi, Rosenh. 

 Mr. Ci'otch (loc. cit.) proposes to sink Mr. Waterhouse's 

 S. pi/gmcea, which he admits is entitled to priority, in fa- 

 vour of this name, because pygmceus is already in use in 

 Ochthebius! 



LiMNEBius ATOMOS, Dufts., Fauu. Austr. 245, 11 {Hydro- 

 pJdlus). 

 Mr. Crotch (loc. cit.) deposes the picinus of Wat. Cat., as 

 there is nothing salient in Marsham's description of that in.
