Mr. Brown has sent four specimens of Drusilla, one male and three females. The male and one of the females agree closely with Vollenhoven's Plate, and seem to represent the true D. anableps. The other two females offer a certain amount of variation, of which we are not yet able to ascertain the value. It may be that the specimens of D. anableps were taken on one island, and the other two females upon another ; but on this point we have as yet no information. In order to draw attention to these aberrant specimens, we append a description of one of them. Exp. 4*3. Dark brown, an oval white spot between the end of the cell of the anterior wings and the anal angle, but nowhere touching the outer or the inner margin ; hind wings with a similar lunate spot, the horns clasping a large ocellus composed of an outer dark margin surrounding a circle of pale fawn-colour, having a black pupil pierced with a white spot: beneath as above, the white spot of the anterior wings being rather larger ; the posterior wings have in addition an ocellus near the apical angle, round the inner margin of which the white patch is extended in a narrow curved line. NYMPHALINHE. 11. C Y N T H I A INSULARIS, sp. n. 2 Exp. 4*4. A n insular race of C. Juliana (Cr. Pap. Ex. t. 280. f. A , B ) from Amboyna, differing chiefly in the position of the white band, which in C. Juliana crosses the hind wings inside the ocelli. In the present insect this band passes through and outside these ocelli, and between it and the outer margin of the wing are two submarginal dark undulating lines separated by whitish lunules. The general colour of the base of the wings is rich brown, without any greenish tinge ; beneath, the principal band which crosses the hind wings is straighter and broader than in C. Juliana, and dark brown instead of black. A single female (the sex by which the races of Cynthia are most easily distinguishable) is in the collection. W e have also compared it with the type of C. ada, Butl. P. Z. S. 1873, p. 686, ex Queensland, and find it distinct. 12. RHINOPALPA ALGINA? Vanessa algina, Boisd. Voy. Astr. Entom. p. 122 ; Hombr. & Jacq. Voy. Pole Sud, Zool. iv. p. 390, Atlas, t. 2. f. 8, 9 (Triton Bay, N e w Guinea). The single specimen sent has the fulvous transverse band of the anterior wings nearly straight, and thus resembles the figure cited above. In this respect it differs from R. amelia, Guer. (Voy. Coq. Zool. p. 278, t. 14. f. 1), where this band is distinctly angulated, as |
