10. DrusiLLA ANABLEPS. 
Drusilla anableps, Voll. Tijdschr. v. Entom. iii. p. 40, t. 1. f. 3, 
and t. 2. f. 1 (1860) (Otaheiti). 
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. anadleps were taken on one island, and the other 
two females upon another; but on this point we have as yet no in- 
formation. 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.

11. CyNTHIA INSULARIS, Sp. 0. 
Q Exp. 4°4. An 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 erosses 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. We have also compared 
it with the type of OC. ada, Butl. P. Z.S. 1873, p. 686, ex Queens- 
land, 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, New 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, Guér. (Voy. Coq. 
Zool. p. 278, t. 14. f. 1), where this band is distinctly angulated, as
