Show 1880.] LEPIDOPTERA FROM CANDAHAR. 409 (C. pallida), but for the fact that I have never taken it at Jutogh or elsewhere. I caught several specimens in the lucerne gardens here, owing to their being very conspicuous; but they are rare compared with the above species : April, May, and June. A few specimens have less orange and more nearly approach no. 2." In Kirby's Catalogue this species is regarded as a variety of C. erate; but Dr. Staudinger hazards the suggestion that it may be a hybrid between C. erate and C. edusa ; unfortunately for the latter view, C. edusa does not exist at Candahar. 16. COLIAS ERATE (no. 2). Colias erate, var. $ pallida, Staudinger, Cat. Lep. Eur. p. 3. no. 54 (1861). "This and no. 21 (C. sareptensis) are found here throughout the year, and are both abundant in June in lucerne fields. I was unable to find the larvae of any of the Colias." Major Roberts has sent both white and yellow females of this species. H e states also that the female is " yellow or white ;" otherwise I should have suspected it to be a local race of the European form. 17. COLIAS SAREPTENSIS (no. 21). Colias hyale, var. sareptensis, Staudinger, Cat. Lep. Eur. p. 5. no. 48(1871). Major Roberts says, "This is in some cases very difficult to distinguish from no. 2, as I have caught the sexes together which appear to represent <$ no. 2 and $ no 21 ; and often I a m unable to distinguish the sexes in no. 21." From this observation I should think it likely that the female form to which Dr. Staudinger has given the name of pallida is a hybrid between C. erate and C. sareptensis *. 18. TERACOLUS FAUSTUS (no. 26). Papilio fausta, Olivier, Voy. l'Emp. Oth. Atl. pl. 33. figs. 4a, b. (1801). " Caught seven or eight specimens, all males, along the dried-up bank of the river, between the 20th June and 2nd July. Probably the females would have appeared in July ; but I was unable to go out after them." 19. BELENOIS MESENTINA (no. 8). (Plate XXXIX. fig. 6.) Papilio mesentina, Cramer, Pap. Exot. iii. pl. 270. figs. A, B (1782). " Rare in April, but abundant in June." The examples sent were taken at the end of June. Major Roberts sends the following description of the larva and pUpa : - « Larva 118. About 1" long. Back and sides smooth and 1 Major Roberts has sent sexes of both species taken in coitu; one sent as "no. 21 " is certainly a yellow female of " no. 2," and vice versa with a white female sent as " no. 2." |
