Note. — Fieber described this species in 1848 (Synopsis Corisarum 
Europse) under the name of Gorisa abdominalis, but in 1.851 (Species 
Generis Corisge) he redescribed it under the name of G. Fahricii,vf lihoxit 
giving any reason for the change. Wallengren and Flor have since 
adopted the latter name, as also has Fieber again in the " Europaischen 
Hemiptera," so that as the species has become generally known as G. 
Falricii, we have not revived the prior name, prefixed to a short and 
somewhat meagre description, although in strictness the latter should 
be the name used.

DESCRIPTION OF A NEW SPECIES OP BIBIO. 
BY G. H. TEEEALL. 
On the wings of this and allied species of Bihio, only two blackish, 
strongly-marked veins reach the margin, the first of these (the sub- 
costal) ends in the stigma, the other (the cubital) springs from the 
first at about two-thirds of its length, and ends before the tip of the 
wing. From the base of the wing another blackish vein (the discoidal] 
starts, which becomes indistinct about the middle, shortly afterwards 
forking and ending in two indistinct veins below the tip ; this vein, at 
the end of its blackish portion, is connected with the base of the cubital 
by a blackish oblique transverse vein, — which I call the transverse vein 
as in the whole order of Diptera it is the chief connecting vein between 
the front and hinder portions of the wing.
