Eastern Biitterjlies. 81 



4. Pkothoe Westwoodii, n. sp, 



Mynes Leucis, var. Y., Hewitson, Proc. Zool. Soc. 1862, 

 p. 88. (?). 



Form of wings as in P. Mulcleri, but the anterior are 

 less rounded, and the posterior more produced behind 

 into a broad tail. 



Male. Above, resembles P. Mtilderi, but the spots are 

 less divided by the nervures, and the base is much less 

 ashy. The large spot on the hind-wings is obliquely 

 truncate towards the anal angle, not regularly rounded 

 as in P. Miilderi. Beneath, the spots on the disc are 

 paler and larger, the marginal spots very small on the 

 upper wings, the yellow caudal spot much larger, and the 

 two pairs of blue lunules above it united so as to form 

 complete heart-shaped figures. 



Female. Differs from the corresponding sex of P. 

 Mulderi by the white patch on the anterior wings in- 

 cluding the two lower submarginal spots. The markings 

 are either pure white, or rather paler yellow than in the 

 male. 



Hab. — Aru Islands. 



The decided difference, both in form and markings, 

 although slight in amount, induces me to consider this a 

 distinct species. 



5. Prothoe Hbwitsoni, n. sp. 



Mynes Leucis, var. G., Hemtson, Proc. Zool. Soc. 1862, 

 p. 88, pi. ix. f. 4, ? . 



Hah. — New Guinea, Mysol. (Wall.) 



The male agrees very closely with Mr. Hewitson's 

 figure of the female, the yellow bands being somewhat 

 narrowed, a little better defined, and more deeply 

 coloured. The underside has the same markings as 

 the upperside, with the basal and marginal spots and lines, 

 as in the allied species. 



The three specimens which I possess, including both 

 sexes, agree so closely with each other, and are so re- 

 markably different from the allied forms, that I have no 

 hesitation in considering it a distinct species; and have 

 much pleasure in naming it after the gentleman to whom 

 we are indebted for thousands of accurate and beautiful 

 figures of butterflies.
