NOVITATES ZOOLOGICAE XXlI. 1915. §§ 



Frnhstorfer {Stett. Eiit. Zeit. 1908, p. 53) calls this species "a ? forma 

 pseudinsularis nova (= insalaris Dist. nee Horsfield)," and I received from 

 Staudinger, apparently in accordance with this, specimens of insulans labelled 

 "pseudinsularis," and of msophila labelled " insularis." 



How this cnrions assertion arises I do not know ; Staudinger's pseudinsularis 

 is certainly identical with the Horsfield type in the British Museum, as it is 

 identical with specimens I have compared with the type, and I accept Distant's 

 figures as fairly good of the species, which is so distinct in its underside markings 

 that it can hardly be confused with anything else. 



Frnhstorfer makes this statement so categorically that one supposes he has 

 examined Horsfield's type ; if so, some mistake must have arisen in the notes 

 taken, or in some other way. I have not studied Fruhstorfer's paper closely 

 enough to say that there are no other faulty identifications, but that is my 

 impression. 



The localities of the specimens at Tring are N.E. Sumatra, 7 <?(?, 3 ? ? ; 

 W. Sumatra, 2 c?c? ; Sumatra, 2 S S ; Mt. Tahau (Mai. Pen.), 2 S i \ Selangor, 

 1 ? ; Banka, 5 (?(^, 5 ¥ ¥ ; Java (Felder coll.), 1 S ; Borneo, 1 cT.

This species has had attributed to it portions, and indeed the whole of the 

 following species, acuta. 



The $ appendages at once distinguish them ; the size and form of the aedeagus 

 differ so as to be at once recognisable, and appear to be quite constant in the very 

 considerable number of specimens that I have examined of each species ; that is, the 

 extreme variations in each species still leave a marked gap between them at their 

 nearest approach to each other. 



There are various named forms of bulis, such as discalis Moore, stigmata 

 Moore, malayica Felder, to which I add santana Horsf. & Moore, and felderi 

 Distant, though these require a little more discussion. 



angulata Moore is no doubt a form of acuta, but it so happens that there 

 is a very similar form of bulis, and these two (both of which occur in collections 

 under the name angulata) come from the same region (N.W. Himalayas), whether 

 from the same localities or not I do not know, but this area is the extreme northern 

 range of bulis and the extreme western of acuta.
