Male. Anterior wings above blackish, with tin' followin'^ Iduish-groy markings :— a broad cellular 

 streak, a large spot occupying about two-thirds of the area between the third median nervule an.l the 

 submedian nervure, a smaller siiot between the second and third median nervules, a sublunulatc spot at 

 end of cell, two contiguous spots beyond end of cell (these are sometimes fused with the marginal spots), 

 and a series of submarginal elongate spots placed between the nervules, of which the two lowermost are 

 shortest and more or less relieved with greyish. Posterior wings above with a bright carmine-red patch at 

 base, and occupying basal third of cell, which is followed by a transverse bluish ])atch : apex of cell and the 

 area from the upper median nervule to apex of wing blackish, remaining portion bright yellow: neuration 

 and outer margin black, narrowing towards anal angle and inwardly angulated at the nervules. Anterior 

 wings beneath as above, but with the si)ots larger and more marked with greyish. Posterior wings Ijeneath 

 with a large and outwardly transverse basal patch of carmine-red, broadly margined with blackish; 

 remainder of wing bright yellow, the neuration and outer margin black. Body above and thorax Ijeneath, 

 with legs, black, shaded with bluish ; abdomen beneath greyish. 



Exp. wings, <? , 55 to 70 millim. 



Hab. — Malay Peninsula; Penaug (Biggs— coll. Dist.) ; Province Wellesley (colls. Dist. and Saiier) ; 

 Singapore (Wallace). 



The female of this species is unknown to the writer, and the male was alone described by 

 Mr. Wallace. It is allied to the ludian D. puramus, and bears a similar relationship to that 

 species as we have seen to exist between D. dione and 1). pasitliDf. 



3. Delias ninus. 



Thyca ninus, Wallace, Trans. Ent. Soc. ser. 3, vol. iv. p. 347, u. 9, t. 7, f. 1 (1867). 

 Delim ninm, Butl. Proc. Zool. Soc. 1872, p. 29, n. 2. 



This species is only known to the writer by the figure and 

 description given by Mr. Wallace, Iwth of which are here reproduced. 



" Closely allied to T. pi/ramus, Wall. Male. — "Wings broader, uppers more 

 triangular, the outer margin not concave and produced. Above : ujiper wings , 

 marked nearly as in T. pt/nimn^, but the ground C(jlour is blacker, and the 

 basal patches bluer and less elongate ; lower wings witli the red patch at the 

 base much smaller, not tilling one-third of the cell, below it a broad transverse 

 bluish-ashy band, paler at the al)dominal margin, a large ochre-yellow patch Fig. hs.—hwi.i.s- »/«»,< j . 

 at the anal angle divided into four parts by the nervures ; outer angle black, 



without whitish markings. Beneath almost exactly as in T. pi/ramus, but the red semicircle does not 

 extend quite so far down, and the posterior markings of the liind wing are more clearly defined, and 

 of a nearly uniform ochre-yellow." 



Exp. wings, "3 inches." 



Hab.— Malay Peninsula ; Malacca; Mount Oiihir (coll. Wallace). 



Mr. Wallace accurately states the systematic position of his species in the following terms:— 

 This insect differs so clearly iu form, size, mar 



arkiugs, colouration, and locality from its alhes,
