 Osborne, of Milford, Ireland, horn. Zanea /(isciata (Ent. 

 Mo. Mag., XX., 145). Holmgren, who named and de-

 Kongl. Sv. Vet. Akad. Hand., B. ]3, No. 12), was only 

 acquainted with the female. The male is very similar, 

 but dijffers in the following points : — The face, clypeus, 

 and mandibles are white, as are the tubercles before the 

 wings, the front and middle coxae, and trochanters ; the 

 middle coxae are black above, and the hind trochanters 

 white beneath ; the base of the hind tibiae is white almost 

 to the middle ; the anterior tibiae and tarsi are entirely 

 white, or rather white slightly stained with ochre, and 

 the apical joint of the hind tarsi is whiter than in the 

 female.
