28. Cyrestis ganescha. 



Amathusla ganescha (part.), Kollar in Hiig. Kaschm. iv. 2, p. 430, 

 pi. 7. figs. 3, 4 (1848). 



c? . Muriee, 9th August. 1885. 



"Eare, only three specimens taken ; probably not more than four 

 specimens seen in all." — J. W. T. 



Kollar apparently regarded C. thyodamas as the other sex of this 

 species, and in this error he has been largely followed. If it proves 

 to be a seasonal form or dimorphic representative of that species, it 

 will indicate a similar condition of things as probably existing 

 between C. lutea and C. nivea of Java, which differ precisely in the 

 same way, although in a more marked degree. 



C. thyodamas is a white species compared with C. ganescha ; the 

 apical area of its primaries is always suffused with blackish, which 

 has the effect of a quadrate apical patch ; this character does not 

 appear in Kollar's figure, which is evidently taken from what I (on 

 that account) regard as typical G. ganescha — the more or less 

 yellow-tinted form ; but in the description — " Vor dem Ausseiirande 

 ist das Feld ausserhalb der fiinften Linie niehr oder weniger schwarz 

 getriibt " — it is evident that both ty[tes are included ; and the remark, 

 " between male and female I find no other difference than that in 

 the latter the marking is more lively and intense," shows that 

 C. thyodamas was supposed to be the female, whereas this sex seems 

 to be very much rarer than the male in either of the Indian forms.

29. LiBYTHEA LEPITA. 



Libythea lepita, Moore, Cat. Lep. E. I. Co. Mus. i. p. 240. n. 519 

 (1857). 



c? $ , 2nd, 12th, 16th, and 23rd August, and 8th September, 1885; 

 5 , Lumbahdun, 27th November. 



S var. (without hatchet-like termination to discoidal streak), 

 Thundiani, 24th September. 



" Common at Murree in August and September. Only two 

 specimens of this Butterfly were taken in the neighbourhood of 

 Campbellpore — one near Lawrencepore 22nd November, and one at 

 Lumbahdun in the Chittar Pahar, 27th November." — J. W. T. 



Major Yerbury appears to think that L. myrrha exists in his series 

 of this species; the latter, however, is easily recognized by the un- 

 broken tawny stripe on the primaries, intersected by the median 

 vein and its two first branches, and by the larger, entirely tawny, sub- 

 apical spots ; the direction of the tawny stripe on the secondaries 

 differs a little, and it is longer and not zigzag along its outer edge. 

 No lepidopterist possessing examples of the two species could possibly 

 confound them.
