DESCRIPTIVE CATALOGUE. 



portions by the passage of the fulvous striga, bearing near the middle two silvery lumiles 

 opposed to each other ; the series is terminated by a black streak, extending in contact with 

 the fulvous band along the oblique portion of the inner margin, being nearly concealed by 

 a corresponding streak of silvery irrorations ; the anal appendage is black, and surrounded by a 

 lax cJHated white fringe which is broader internally ; the thorax and abdomen are brown 

 above and white underneath, the latter being banded at the sides ; the feet are white annulaled 

 Avith black ; the antennce are also delicately annulated, and the club has a broad white ring at its 

 base and a ferruginous tip. 



The resemblance, in general habit, in the outline of the wings and in the chai-acteristic marks of the lower 

 surface, between the two species last described, is so striking, as to cause an inquiry, whether, notwith- 

 standing the palpable difference in colour, they might be no more than different sexes of the same 

 species. A careful examination has however convinced me that this is not the case. In No, 28 the upper 

 surface of the hinder wings is without the least indication of the ocellate spots in the anal region; in 

 the lower surface the fascia, dividing the posterior portion of the fore wings, has a different direction, and 

 in the hinder wings of the same species the dimidial portion has not any indication of a transverse discoidal 

 striga, whereas No. 29 has a very distinct transverse line on the disk of the same wings. Our collection 

 contains six specimens of Theda Chitra and seven of Thecla Nedymond, which individually closely agree with 

 the description given of them. 



It is my duty to caution the reader against confounding our 28th species with the Polyommatus Nedymond 

 of the authors of the Encyclopedic, and to state the reasons of my differing in this instance, from the learned 

 authors of that work. Our 28th species, according to my judgment, is distinctly figured on the 299di plate of 

 Cramer's work, with the name of Papilio Nedymond. This specific name is applied, in the Encyclopedic, 

 to an analogous species, which is also described in this catalogue in the next subgenus in its proper section ; 

 and the authors of that work, perceiving some discrepancies between the latter species and Cramer's figure 

 of the former, point them out in a note. These discrepancies relate chiefly to the anal appendage and the 

 tails, and to the colours and markings of the anal region of the posterior wings underneath. Possessing 

 specimens of both insects, I have been enabled clearly to identify Cramer's figure with our 28th species ; 

 and the detail of the peculiarities of the analogous species, will afford the means of a distinct discrimination.
