Mr. A. G. Butler on Madagascar Lepidoptera. 333 



detected in every cell of the green tissue, especially in Pinus 

 maritima. 



From the facts here communicated I believe that I have, in 

 the first place, established anatomically and microchemically 

 the individuality of the hypochlorin in the chlorophyll-bodies, 

 and proved the necessity of light for its formation in the 

 Angiosperms. With regard to the physiological relations 

 of chlorophyll to hypochlorin I have already given some 

 intimations, and expressed the opinion that chlorophyll, by 

 means of its absorption of light, protects the hypochlorin from 

 combustion in intense light. Upon the presumable genetic 

 relations of chlorophyll to hypochlorin my investigations are 

 not yet completed. 



XXXII. — On a Collection of Lepidoptera from Madagascar, 

 with Descriptions of neio Genera and Species. ByAETHUR 

 G. Butlee, F.L.S., F.Z.S., &c. 



The following species have been selected from a large 

 collection made at Fianarantsoa by the Rev. W. Deans 

 Cowan. 



Rhopaloceea. 



Nymphalidae. 



Satybinje. 



1. Gnophodes hetsimena $ . 

 Cyllo betsimena, Boisduval, Faune Mad. p. 58. n. 1 (1833). 



A fine specimen. 



In my Catalogue of Fabrician Lepidoptera I erroneously 

 sunk this species as a synonym of G. pythia ; now that we 

 possess both I find the Madagascar species much nearer to the 

 G. parmeno of Trimen from Natal, which is of the same size 

 and form, but instead of a broad oblique white belt on the 

 primaries has a rather narrow angulated ochreous one. As 

 the G. parmeno of Trimen is not identical with the West- 

 African form, I propose to call it G. diversa. 



2. Pseudonymplia subsimilis. 



Pseudomjmpha subsimilis, Butler, Ann. & Mag. Nat. Hist. ser. 5, vol. iv. 

 p. 228. n. 3 (1879). 



The type was also taken at Fianarantsoa.
