CYDIMONID^. 41 



Guinea and the adjacent islands. They are stout Ijodicd, 

 day-flying ^[oths, with long palpi, anlcnncX considerably 

 thickened before the tip, and transparent black-bordered wings 

 about three inches in expanse ; towards the base is frequently 

 a large orange patch. The hind-wing cell is divided ; and on 

 the fore wings, the basal half of the inner margin is much ex- 

 panded, the sub median nervure being bent downwards at this 

 point almost at a right angle. The typical species is Cocytia 

 durvillii^ Boisduval. 



FAMILY VI. CVDIMONID^ (PAGES). 



This Family, which is usually known under the name 

 Uraniidce, has been discussed by Westwood in the "Transac- 

 tions of the Zoological Society," x. pp. 507-542. Summing 

 up the work of previous authors, he tabulates the group as 

 follows : — 



A. Fore-wings with the fifth branch of the sub-costal vein emit- 

 tinf' the upper discoidal vein; at a considerable distance 

 beyond the discoidal cell. 



a. {Cydimon, Dalm.) Palpi with the terminal joint 

 very short. 

 * (Qv/////^///^*^, Blanchard,Guent'e.) Hind-wings 

 with the second and third branches of tlie 

 median vein produced into the long tail ; 

 second branch of the sub costal vein free. 

 — Genus Ur.\nii)I.\, Westw. ; type, U. Iciliis. 

 ** {Urania, Bhmchard, Guenee). Each of the 

 veins of the hind-wings prolonged into a tail ; 

 second branch of the sub-costal vein of the 

 fore-wing coalescingwith the third branch half- 

 way between the cell and the tip of the N\ing. —
