This is an interesting varietv in which the 

 markings on the primaries are suffused with tin- 

 giving them a very uniform character. That this is mere variation 

 and has no specific value is evident from the fact that we ha\e an 

 example in the Museum in which the left primarv is similariv 

 suffused, whilst on the right primary many of the white marki;"js 

 are present.

This is the only fairly perfect example 1 have ever seen the 

 species having hitherto only reached us from Dr. Gregory's 

 collection, and so much rubbed and shattered as to be barely 

 recognizable. Unless Felder had a very closely allied specie-, his 

 figure is incorrect (probably made up from an injured specimen, 

 as the outer black edging to the central bell of the primaries is 

 deeply and coiiically incised between veins 2 and .'>).

The larva of this moth (which is quite new to the Museum 

 Collection) is said by Mr. Betton to have been common at Taru on 

 December JOth; the present example pupated on December 17th, 

 1896, and emerged at the end of the following March. The larva 1 

 and pupa, which Mr. Betton preserved, were unfortunately u<>t 

 sent to ns with his collection; he refers to the former as " bottle 

 of larvae marked Taru, Nov. '2'^ to Dec. !">. lsi)i;." and to tin- 

 latter u see matchbox marked ' M.' " 



If Mr. Betton could breed a series of this Saturniid, I 

 would be conclusively proved that />'. fut re". v Maassen \\a: 

 variation ; it certainly is extremely closely related, if di-ti 

 the fact that both occur at Zanzibar is very suspicious.
