64 MR. W. C. HEWITSON ON LEPIDOPTERA [Feb. 10, 



Obs. Similis Piprce gutturali, sed gutture circumscripte albo, crisso 

 albo terminato et primariis intus cineraceis facile distinguenda. 



I should add that the first primary in the single specimen that I 

 possess of this bird is remarkably diminutive, measuring only 0*6 

 inch from the insertion to tlie extremity, and being very much 

 narrowed. The second, third, and fourth primaries are also much 

 narrowed towards their terminations. My belief is that this is an 

 abnormal formation peculiar to the male bird, somewhat analogous 

 to that which I have described in Machceropterus* ; but before 

 stating this as a certainty, I should wish to see more specimens of 

 the species, as, without spoiling the skin, it is difficult to be quite 

 certain whether the first primaries are fully grown or not. 



3. A List of Diurnal Lepidoptera taken in Madagascar 

 BY Mr. Caldwell. By W. C. Hewitson, F.Z.S. 



(Plate XI.) 



A small collection of Diurnal Lepidoptera from Madagascar, which 

 has been sent to me for examination by Dr. Sclater, is stated to have 

 been formed by Mr. J. Caldwell chiefly in the neighbourhood of 

 Antananarivo, except the Diadema dexithea, which was captured 

 near Beforona, just before entering the great forest of Alamazaotra. 

 It contains the following species : — 



Papilio demoleus. 



A common African species. 



Papilio oribazus, Boisduval, Species General des Lepido- 

 pteres, p. 223. 



A very rare species, the only examples of it sent to Europe up to 

 the present time being two specimens in the collection of Dr. Bois- 

 duval of Paris. The males of the nearly allied species P. nireus 

 (of which P. erinus of G. R. Gray is only a variety), P. phorbanta, 

 and P. disparilis have each on the underside of the posterior wing 

 a submarginal band of silvery white spots, whilst this species, which 

 is without these said spots, closely resembles their females, and in 

 this respect is most nearly allied to P. charopus of Westwood.

Pieris mesentina, Cramer, pi. 270. 



A species common to Africa and India as well.
