Four males and two females. Kurrachee, May and June 1879. 



Four of the specimens, including the females, are labelled " 3 ;" 

 the other two, males, are labelled "4." The following species (if 

 indeed it be distinct, which I begin to doubt) is similarly mixed up, 

 one male and two females being labelled "3," and two males "4." 



37. Teracolus bimbura (Nos. 3 & 4).

Three males and two females. Kurrachee, May 1879. 



This form differs from T. purus in the narrower blackish borders 

 to the apical orange patch in both sexes, the smaller marginal spots 

 on the secondaries, the usually slightly inferior size ; the difference 

 of irroratiou on the under surface of the secondaries seems to be 

 confined to specimens taken in Cashmere ; but my figures of the 

 upper surface accurately represent T. bimbura of Kurrachee. My 

 figure of T. purus $ doubtless represents the female of 1\ etrida, 

 which, when I wrote my " Revision " of the genus, was a rare 

 species in collections, and consequently not readily recognized by me. 

 The true female of T. purus is of about the same size as the male, 

 and has a more curved orange patch on the apical area ; the mar- 

 ginal spots on the secondaries are also rather smaller than in 

 T. etrida $ ; and the spots across the disk of these wings on the 

 under surface are less conspicuous.

One male and two females. Kurrachee, May and June, 1879. 



This species is also said to occur in July and August. It is easily 

 separable from T. dulcis by the much broader and darker grey 

 patch at the base of all the wings, by the larger marginal black spots 

 on the male, and the presence of an additional series of discal black 

 spots on the disJc of the secondaries on the female — a character wholly 

 failing in Kurrachee females of T. dulcis, and never represented 

 elsewhere excepting by one or two indistinct spots : the under sur- 

 face of the female secondaries also inclines to yellow in tint, whereas 

 in T. dulcis it is quite pink.

Three males and two females. May and June 1879. 



Major Swinhoe gives the following months for the appearance of 

 this species : — " January, August, and November." It is possible, 

 however, that he may have confounded it in life with the preceding
