Genus CLEIS Gu^rin. 



167. C. dichroa (Boisduval), Voyage Astrolabe, L4p. p. 260.

There are two species of Cleis in the collection, each represented by both sexes 

 The determination of these is a matter of some difficulty. Boisduval, I.e., describes 

 a species of this genus from Buru under the name dichroa. His description is as 

 follows : " Ailes d'un noir brun ; les superieures avec une bande transverse orang^e, 

 commenfant a la cote ; les infdrieures sa/iia taches * ; (femelle) ayant les inf(5rieures 

 avec une bande terminale orang^e ; dessous semblable ; celui des superieures avec 

 quelques petits traits violets." 



Now this description of the male given by Boisdu\'al exactly applies to the 

 male of one species, and of the /«ma^e to the female of the other species. 



I solve the problem by taking the name dichroa Boisduval for the male, the 

 fe/male of which is exactly like the m.ale in the colouration and markings of the 

 wings, except that the orange band of the primaries is reduced in width and not so 

 conspicuous. 



The other species, of which I have five raales and six females, has an orange 

 band on the secondaries, obsolescent on the upperside in most examples, though 

 always indicated, but very conspicuous on the lowerside. The female has this 

 band enlarged and conspicuous on both the upper- and lowersides of the secondaries, 

 while there is a strong tendency in the transverse band of the primaries to become 

 obsolete in this sex. In one example it is broad and conspicuous, and in another 

 it is reduced to a small orange spot near the outer angle, and the two are connected 

 by intermediate forms. Both males and females are exactly alike on the underside. 



This species is, I think, without doubt Gleia propinqua Butler, see Pagenstecher, 

 Jahrb. Nass. Ver. Nat. XL. p. 222. 

 The synonymy works out thus : — 

 a. Cleis dichroa Boisduval ; male. 

 h. Cleis jyi'ojpinqiia Butler ; male. 



„ dichroa Boisduval ; female. 

 The species figured as dichroa by Pagenstecher, Jahr. Na^s. Ver. Nat. XL. 

 t. 1. f. 7. 8, is not the insect found in Buru, whence Boisduval obtained his types. 

 Unfortunately, Dr. Pagenstecher does not indicate the sex of the specimens figured.
