172 Mr. H. Grose Smith on new 



Crown of the head and a broad crescentic band across the 

 neck black. A pair of red spots separating the collar from 

 the black crown. A black band descends from the eye to 

 the infralabials. Lower parts whitish. 



Total length 160 millim. Length of tail 90 millim. 



This species would belong to Fischer's genus Cryptodelma, 

 which has been separated from Delma. on account of the 

 presence of praeanal pores. However, a comparison of the 

 allied species will show that this technical character leads to 

 a rather unnatural subdivision of the genus.

 Pacific Islands. By H. GROSE SMITH, B.A., F.E.S.,

Papilio oberon. 



$ . Upper side brownish black ; anterior wings crossed 

 obliquely, at about one third from the apex, by a row of white 

 spots arranged as in P. cegeus, Don., but the spot between the 

 lowest subcostal and upper discoidal nervules is quadrate and 

 not indented externally. Posterior wings with a brownish- 

 white band of spots divided by the veins as in P. cegeus, but 

 the inner edge of this band slightly invades the cell as in 

 P. ormenuSj Guer., and the outer ends are rather more in- 

 dented and approach nearer the outer margins; above the 

 anal angle is a large suboval brick-red spot. 



Underside. Anterior wings as on the upperside ; the oblique 

 row of spots is broader and irrorated with grey on the inner 

 side. Posterior wings with a row of six brick-red lunules 

 crossing the disk from the submedian nervure to the apex, those 

 nearest the anal angle the smallest, gradually increasing in 

 size, the apical spot being the largest of them j another brick- 

 red spot, larger than the last-named spot, is situate above the 

 anal angle; inside the row of red spots are two rows of 

 greyish markings, the outer of which consists of three narrow 

 bluish-grey hastate lines between the submedian nervules, 

 above which, divided by the veins, is a row of seven bars of 

 grey scales, indented outwardly, those on either side of the 

 uppermost median nervule being the broadest and most 

 indented, the two bars nearest the apex nearly obsolete. 



Expanse of wings 4^ inches. 



Hab. Santa Cruz (Woodjord). 



Very near P. cegeus, Don.
