Undet-sulc : Corewiugs with a few whitish scales between the fourth and 

 tifth subcostal uervuL-s. Jliudwiufrs with the submarj,'iDal luiinles much increased, 

 trans versally of more than half the breadth of tlie respective celhiles ; marginal 

 spots also larger than above.

4. Papilio hipponous lunifer subsp. uov. 



Much larger than P. hipponom Feld., the forewiugs measuring GO mm. in 

 a straight line from the base to the aije.\. Outer margin of forewiugs more cducave, 

 submarginal ill-defined band broader. Hiudwings a little more produced in caudal 

 region, discal band much narrower and of more even breadth, the second spot 

 scarcely as long as broad, tlie third a little longer ; on the underside this baud is 

 still narrower than above, and the submarginal lunules are proportionall}- larger and 

 more arched than in P. hipponous Feld.

ON A NEW GENUS AND SPECIES OF BUTTERFLY. 



By THE HON. WALTER ROTHSCHILD. 



Anaeomorpha gen. uov. 



This genus stands midway between Auaeo, liidMi. and Pivpoiia Boisd. From 

 Prcpoim it difl'ers in its short forewiugs, sharjdy pointed at the ai)ex, and its 

 rounded hiudwings, which rnn out to an acute taU-like iioint at the anal angle. 

 From Anaea it differs in having the big head, long and sharply ])ointed jtalpi, and 

 long stout antennae, scarcely thickened towards tlie point, whicli are so characteristic 

 of Preponn. 



Anaeomorpha spleudida sp. nov. 



Upperside : J'urewliigs sbarjjly triangnhir, with apex produced and much 

 pointed ; basal two-thirds brilliaut shining metallic green; at apex of cell is a large 

 irregular velvety black ]iatch ; outer third black, forming a wide black border to 

 the wings. 



Hindivings shaped as in Bia actorion (Linn.), i.e. rounded and running out 

 into a tail-like projection at the anal angle ; black, with a clothing of thick dark 

 grey hairs along the abdominal margins ; from the base outwards the centres of the 

 wings are crossed by a large and very broad half-moon-shaped liand of shining 

 green, which curves round towards the anal angle. 



Antcmiae red ; abdomen, thorax, aud head greyisli black. 



Vndcrside: head, thorax, abdomen, 'MxA two-thirds of «7/(^.s clay brown ; basal 

 third of costa pure white ; outer third of wings freckled with grey, as in Anaea. 

 From the apex of forewiug to anal angle of hindwing the wings are crossed 

 by a narrow transverse black baud. 



Exjianse : 88 mm.
