ACR.EA. 35 



fore-wings transparent ; there is a black bar closing the cell on 

 the fore- wings, and sometimes one or two small adjacent spots; 

 the hind-wings are spotted with black at the base and in the 

 cell, and have an irregular row of spots beyond and below the 

 cell ; the hind-margin is black, with a row of red spots, hardly 

 separated from the red part of the wing on the inner side. 

 The female is more transparent, and the reddish colour is re- 

 placed by ochreous. It expands from 2 to 2^ inches. The 

 larva feeds on passion-flowers in gardens as well as on native 

 African trees. It is a very common Butterfly in South Africa, 

 and birds will not eat its spiny, strongly-smelling larvae.

The typical section of Acr&a includes most of the species 

 with more or less transparent wings, Doubleday called it 

 Hyalites, in allusion to this feature ; and therefore Dr. Scudder 

 is wrong in proposing to restrict the latter name to A. encedon 

 (Linn.), an opaque species, which Doubleday considered to form 

 a separate sub-section. If, however, any hyaline species in- 

 cluded by Doubleday under Hyalites should be considered 

 generically distinct from A. horta, then the name Hyalites 

 must be revived for it; but not otherwise. Mr. Trimen 

 unites the following sections under Acr&a : Hyalites, Doubl., 

 Gnesia, Doubl., Telchinia, Hiibn., and Pareba, Doubl. In 

 this he may be correct, except in respect to Pareba, which has 

 much longer and narrower wing-cells than the other groups, 

 with the disco-cellular nervules straight and oblique. The typical 

 species viPareba \sP.vesta (Fabr.), a light ochreous insect, often 

 intersected with light brown stripes. It is about 2^ inches 

 across the wings, and is common in many parts of the Indian 

 Region. Most of the species belonging to the other sections 

 named are African. Tclchinia violcz (Fabr.), a common East 

 Indian species of this Sub-family, is smaller than P. vesta, and is 

 of a warm fulvous colour, with black borders, spotted on the
