INTRODUCTORY PAPKRS ON LEPIDOPTERA. 75 



striated hind wings, and Alana, Boisd., for the smallest of 

 the African species. 



The typical genus, Acnea, Fabr., is exclusively African, 

 if we except a very few Indo- and Austro-Malayan species. 

 In the first section, to which belongs A. Horta, Linn., 

 the type of the genus, the fore wings are more or less 

 transparent, and the hind wings and base of the fore wings 

 are of some yellowish or reddish shade, varying from pale 

 tawny to red, with numerous black spots, or a macular band. 

 In some species the hind wings are creamy white, as in the 

 Australian Ji. Andromacha, Fabr., which has some resemblance 

 to Eurycus Cressida, an insect allied to Parnassius, and 

 likewise a native of Australia. 



The next section contains a great number of closely-allied 

 species or varieties of considerable size, none measuring less 

 than two inches across, and some nearly four. They are 

 dark brown, with the veins of the hind wings strongly 

 marked. The fore wings are banded or spotted with red, 

 white, or pale yellow ; and the hind wings have a band of 

 the same colour, which is often broad enough to cover 

 almost the whole of the wing. A. Euryta, Linn., may be 

 considered the type of this group. 



In the next group, comprising A. Zetes, L., and its allies, 

 the wings are smoky black, with very large spots both above 

 and below, and the fore wings are slightly transparent, often 

 with a short whitish or yellowish transverse band near the 

 tip. The males have a submarginal reddish band, varying in 

 breadth, on the hind wings. 



The next group {Telchinia) comprises the bulk of the 

 smaller species, measuring from one inch and a half to two 

 inches and a half across; and many of them have a super- 

 ficial resemblance to Fritillaries. They are generally reddish 

 or tawny, with numerous black spots or dots, and the borders 

 are black, often spotted with yellow on the hind wings. In 

 some species, as in A. Serena and Eponina, Cram., the tip 

 of the fore wings is more or less broadly black, with a trans- 

 verse whitish or tawny stripe ; and in the latter the base of the 

 hind wings and part of the inner margin of the fore wings is 

 also black. One species of this group, A. Viol(B, F., is 

 common in Northern India; the others are African. 



The next group {Pareba) only includes one North Indian 

 species, A. Vesta, Fabr. It is a long-winged, yellowish 

 tawny insect, with dark borders spotted with yellow. In the 

 female the veins are strongly marked, and the tawny portion
