288 NYMPHALID^E. NYMPHALIN^. CHARAXES. 



"If I have rightly determiuecl this species, it is nearly allied to C. baya, though, apparent- 

 ly, quite distinct ; the British Museum has it from Sylhet." (Butler, 1. c. ) 



This species appears to chiefly differ from C. agna in having the black outer border 

 of the forevving on the upperside marked inwardly towards the inner margin with three 

 elongated spots of the ground-colour. On the hindwing it agrees with C. walti in having 

 the black spots on the margin blind, except the geminated anal one. As identified by 

 me, there is one specimen of true C. corax from Sylhet and two from Cachar in the 

 Indian Museum, Calcutta. There are, however, numerous other specimens from Cachar 

 taken with the above, and one from Tavoy, which show great variation in the size of the 

 spots and the apical patch on the hindwing, in some examples they are almost as broad 

 as in C. iinna as pointed out by Mr. Butler. These specimens also show a transition to the 

 next group in having in some of them two small spots of the ground-colour on the 

 upperside of the forewing on the inner edge of the black outer margin divided by the upper 

 discoidal nervule.

Habitat : Upper Ten.asserim, Province Wellesley, Borneo. 

 Expanse : ^ , 3'2 to 40 inches. 



Description : " Male. Upperside rich fulvous. Fo/eiving with a duplex spot at the 

 upper angle of the cell, and the border as in C. corax, Feider, but in the apical region more 

 broadly blackish-fuscous, ffin.kuing anteriorly a little paler, the virgula evanescent, the apical 

 patch much smaller than in C. corax, and all the spots free, minute, inwardly marked with 

 whitish. Underside much paler than in the said species [C, corax}. Hindioing with a 

 sordid ferruginous-fulvous fascia, decreasing from the second subcostal nervule, very narrowed, 

 the submarginal spots minute, more distant from the margin than in C corax and C. psaphon, 

 the marginal region immediately beyond these obscurely ochraceous." 



"The specimen we have before us is larger than C. corax, Feider, and agrees in the 

 shape of the forewing with C marmax, Westwood, with the exception of the scarcely per- 

 ceplible toothing of the edge. According to the description C. baya, Moore, appears to 

 be a similar species." [Feider, I. c.) 



Mr. Distant remarks that the specimen of C. harpax, Feider, he figures is intermediate 

 between C. agna, Moore, and the typical Bornean examples of the former, and that variation 

 must be allowed where no distinct local race has become difTerentiated. 



"There are both sexes of a species allied to C. corax, Feider, and agreeing very fairly 

 with Dr Felder's description of C. harpax, in the British Museum, from Moulmein : the female 

 of the latter is scarcely distinguishable from C bentanlus female, tbe male is very like C. baya." 

 {Butler, 1. c ) 



The characters which distinguish C. harpax from C. baya have been pointed out above 

 (p. 286). Major Marshall has one specimen of this species, taken by Captain C. T. Bingham, 

 at the Mayla Choung, Upper Tenasserim, in September, and there are three specimens from 

 Perak in the Malay Peninsula in the Indian Museum, Calcutta. Mr. Moore records it from 

 Moulmein to Meetan j Moolai, 3,000 to 6,000 feet. Upper Tenasserim. I have appended 

 Mr. Distant's very full description of this species.* I have never seen the female. 



* "Male. Upperside reddish ochraceous. Forezuing with two small contiguous black spots at upper 

 end of cell ; apex and outer margin broadly black ; this black area has its inner margin sinuous and emarginate,
