Note. — Fieber described this species in 1848 (Synopsis Corisarum 

 EuropjB) under the name of Corisa ahdommalis, but in 1851 (Species 

 Generis Corisae) he redescribed it under the name of C. Fahrieiij without 

 giving any reason for the change. Wallengren and Flor have since 

 adopted the latter name, as also has Fieber again in the " Europaischen 

 Ilemiptera," so that as the species has become generally known as O. 

 Fahricii, 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 OF BIBIO. 

 BY G. H. YEEEALL. 



On the wings of this and allied species of Bihioy 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.

 pilosa, capite, pleuris, scutello, pedibusque nigris ; nervo transverso

females having black legs are the common hortulanus, Lin., and siculus,
