differences pointed out, sucli as size, form, marking, white veining, &c., 

 are constant, there is every evidence that A. Scylla, instead of being 

 regarded as even a doubtful variety, is a good and constant local form, 

 or, in fact, a distinct species. 



In conclusion, I would recommend all Entomologists to beware of 

 excitement about any new craze : a few years ago every unusual patch 

 on a wing, every tuft on any part of an insect, was at once labelled 

 either as some form of scent-bottle or musical box for the delectation 

 of Madame Papilio ; in some cases there was sense in the suggestion, 

 but in nine cases out of ten the most pitiable nonsense : now a new 

 craze has arisen ; wheresoever in any genus two species stand a little 

 apart on account of intermediate links not having yet been collected, 

 the Lepidopterist pounces upon them as probable seasonal forms ; 

 whereas, when one really knows anything of any genus of Lepidoptera, 

 one finds that all the representatives of that genus are reduced to very 

 slightly differentiated local races.

DESCRIPTION OF TWO NEW SPECIES OF BUTTERFLIES. 

 by h. geose smith. 



Papilio Sycorax. 



Upper-side. Anterior-wings olive-brown, the longitudinal rays in the cell, the 

 nervures, and broad bands between the nervures dark olive-brown. Posterior-wings : 

 the inner half somewhat greener than the anterior- wings, the outer half greenish- 

 grey, in the middle of which between the nervures is a row of five large conical 

 black spots, the two upper spots extending to the cell on the inner side ; on the outer 

 margin are five, large, black, quadrate spots confluent on the outer margin, the spot 

 nearest the upper angle is also confluent on the inside with the upper spot of the 

 central row. The outer margin ashy-grey, deeply indentated between the nervures. 



Under-side. Both wings as above, but much lighter, and the outer row of spots 

 on the margin of the posterior-wings are distinct. Head and collar ashy-grey. 

 Abdomen greenish-grey above, underneath orange,:t\vo rows of black spots on either 

 Bide. Exp. 6 in. 



Hah. : Sumatra (Bock). 

 A grand insect, nearest to P. Friapus. 



Charaxes Yioletta. 



Upper-side. $ . Anterior-wings dark brown, suffused slightly with violet, with 

 a curved row of violet-blue spots across the middle of the wings, and a sub-marginal 

 row of similar spots from near the costa to the inner margin, the lower half of the 

 two rows becoming confluent, the two sub-marginal spots near the apex nearly white. 

 Posterior-wings with a broad central band of violet-blue, suffused with white from 

 the second sub-costal nervule to the abdominal fold near the anal angle ; above this 

 band are two pairs of violet-blue spots, a sub-marginal row of seven small spots, and
