NOVITATES ZOOLOGICAE XXII. 1915. 397 



1 (J, Bougainville, Solomon Islands (April 1904, A. S. Meek). 

 1 ¥, Reudova, Solomon Islands (Feb. 1904, A. S. Meek). 

 1 ? , Cedar Bay, Cooktowu (Meek) (Type of b. major Rothsch.) 

 1 ? , North Queensland. 



1 3 S,'i ? ¥ ; 1 cripple, 3 pupa cases, 1 larva, 1 larval skin and series of 

 eggs (Townsville, Queensland, F. P. Dodd. Bred 1901). 



Of these the Bongainville <? is almost blacks. e., where in Strand's castnia 

 the orange band is situated, there is only a very small orange spot, and on the 

 hindwing and basal quarter of forewing are only some faint splashes of deep rufous. 

 The British New Guinea cJ has rather more rufous marks, while the Humboldt Bay 

 and Halmaheira c? <S have basal third of both wings orange. The Rendova ? is 

 identical with, though slightly larger than, the type of robusta Feld. ; while the 

 Rossell Island ? is indistinguishable from some of the bred Queensland specimens. 

 The Perak ? is similar to the Bornean ? . 



From this evidence I am forced, for the present, to consider that only three 

 races can be separated, and that castnia Strand is only a melanistic aberration of 

 b. robusta ; the forms would thus be as follows : 



L. brassolis hrassolis Westw., India, Malacca and Snnda Islands. 



L. brassolis robusta Feld. Moluccas, N. Guinea and Solomon's Island. 



L. brassolis major Rothsch., Queensland and adjacent islands.

158. Arhopala periander Gr. Smith 



Arhopala periantkr Grose Smith, Nov. Zool. i. p. 582. No. 263 (1894) (Jobie). 



1 cannot agree with Mr. Bethune-Baker that this is the same species as 

 philander Feld. That insect has no saturated purple gloss on the underside, being 

 of a particularly soft woolly appearance ; while the present insect, on the underside, 

 looks as if saturated with a satiny purple grease. As, however, the type of 

 periander has unaccountably vanished, I cannot with absolute certainty declare 

 the Jobie insect and these two Dampier Island ones to be identical. 



2 cJcJ, Dampier Island.

Arhopala meander Boisduval, Voy. Astrol. Lep. p. 76. (18ii'2) (Aru).
