232 Mr. A. G. Butler on new Species of 



Papilionidse. 



12. Nychitona sylvicola, Boisd. 



A specimen of this species now received agrees in all points 

 with the description ; the small spot which Dr. Boisduval 

 mentions as usually present is, however, very indistinct ; on 

 the under surface it agrees well with Cramer's figure of N. 

 medusa, said to come from Bengal. We have an example 

 agreeing in all respects with the figure and with N. sylvicola, 

 from the Congo, but none from any part of India. The spe- 

 cimens previously received, and supposed to be N. sylvicola, 

 agree in all respects with N. nupta. With regard to the latter 

 species, which Mr. Kirby supposes to be the female of N. 

 alcesta, I may mention that the sexes are identical, the upper 

 surface being pure white in both ; in N. alcesta, on the other 

 hand, both sexes have a well-defined black spot on the disk 

 and at apex of primaries.

If this should prove to be no more than a variety, it will 

 throw doubt upon the value of several other species in the 

 genus. 



Papilionin^. 



An example of Papilio endochus received with Mr. King- 

 don's series differs from the typical form in the absence of the 

 second black costal patch on the primaries. 



Hesperiidae. 

 14. Trapezites? Kingdom, sp. n.
