&6 iJoVlTATES ZOOLOGICAE XXII 1915. 



Ill this, as ill tlic other species aiul forms, I depend rather on the photographs 

 than on description to convey the characters of the appendages ; in bidis I note that 

 the corunti are very numerous and rattier small, the aedoagns 2'0-3'U mm. long, 

 with a terminal form and armament that is very distinctive. The harpe is smooth, 

 solid, sometimes rather pointed, more often ronnded at the tip, rarely in some races 

 inclined to broaden out. The valve is rather long and narrow, as iu the species of 

 this B section. 



Unauthenticated specimens labelled arcuata Moore from Nias, but really balis, 

 have the harpes rather more blnnt. 



A specimen labelled malai/ica (in Moore's writing) from Burmah has the harpe 

 rather sharp.

The type specimen of malayica agrees with specimens I have examined, 

 obtained from various quarters ; these all prove to be forms of bulls. 



Specimens of bulls from Penang and Province Wellesley have a very close 

 resemblance on the upper surface to acuta ; they are nevertheless bulis.

This name has puzzled me a good deal : two examples so named from the Moore 

 collection proved both by wing markings and genitalia to be sperthis; they both 

 hailed from Java, and are no doubt the same as Staudinger's javana (see sperthis). 

 Boisduval's ligure is of the male upper surface, and might be thetis or various other 

 species. 



There is, however, in the Tring collection a specimen labelled santana that 

 probably represents the name correctly ; it is from the Felder collection, and has 

 labels " Java ell. de Capellen." " Santana, Moore, Java, v. d. Cap." 



1 happen to possess a similar specimen, but from Borneo, at least as labelled. 

 On the upper surface these are not at all unlike titetis, but there are one or two 

 points, such as the produced anal angle of the hindwing, that receive their explana- 

 tion when it is seen that the underside is that of bulis. Both these specimens have 

 appendages the same as those of bulis. 



It appears, then, that santana is a Javan race of C. bulis, iu which the black 

 border is not returned along the inner margin, a feature that characterises bulis almost 

 everywhere else, but the extent of which is so variable that snch a form as santana 

 only carries this variation a trifle farther than usual. If my specimen is correctly 

 labelled, which 1 doubt (it is from the Moore collection), this form also occurs in 

 Borneo. 



There are two specimens, one (No. 4) from the Straits Settlements, that has a 

 certain amount of black along inner margin, and one (No. 20), purely santana in 

 marking, from N. Borneo, that both show the enlarged harpe oi santana.

Mr. Distant writes me that he believes the type specimen is in the Zoological 

 Museum at Tring. I have seen only one specimen, not labelled " type," bat 

 " Felderi, Dist." apparently in Mr. Distant's writing, and a locality label " Sing
