180 REPORT ON ZOOLOGY, MDCCCXLII1. 



same authors (Isis, 1838-39) on the structure of the antennae and the occur- 

 rence of accessory eyes. The legs of the Lepidoptera have not hitherto 

 received the consideration they deserve, although they furnish excellent sys- 

 tematic characters. The authors have here presented us with a store of 

 observations, and it is to be regretted that they have not had at their disposal 

 more complete collections, especially in extra-European Lepidoptera, the 

 examination of which would have conduced to more comprehensive results. 

 This has been fully perceived by the authors themselves. They have, how- 

 ever, drawn attention to many points, and this memoir deserves the most 

 earnest attention of Lepidopterologists ; I am only able, in what follows, to 

 direct notice to certain points. 



With respect to the change of skin by caterpillars, Ashton (Transact. Ent. 

 Soc. of London, iii, 157) has confirmed the observations of Swammerdam and 

 Bonnet, according to whom the most internal membrane of the alimentary 

 canal and of the tracheae is cast off together with the external integument, 

 in opposition to Herold, who contradicts this. Ashtou's observations were 

 made on the larva of Sj>/iin.T Ligustri, and he found in the exuviaj behind 

 the pupa, the internal membrane of the digestive canal, and was able, by 

 maceration in water, to exhibit the fine ramifications of the tracheae. 



Two hermaphrodite Lepidoptera have been described by Zeller (Ent. Zeit. 

 s. 299), Hipparchia Janira and Geometra liclienaria. The author obtained 

 the latter fresh from the pupa ; when impaled it deposited a quantity of 

 barren ova. What a pity that this Butterfly was not examined ana- 

 tomically ! 



PAPILIONES. - A new genus, Teinopalptis, belonging to the Equites 

 group has been instituted by Hope (Trans. Liu. Soc. p. 131), and illustrated 

 by Westwood. (Arcana Ent. xv. pp. 59, 60.) Outline and nervation of 

 wings, as well as the completely formed anterior legs of Papilio, the fore- 

 head, however, projecting and conical, and the palpi elongated as in the 

 Nymphalidse, the antenna short, the club gradually incrassate. Two showy 

 beautifully coloured species, T. imperials and Parrya, are indigenous in 

 Sylhet, perhaps, as the authors suppose, the male and female of the same 

 species, which supposition, notwithstanding their great resemblance, is ren- 

 dered questionable by the circumstance that the former ( ) has a single 

 appendage to the posterior wing, and the latter ( 5 ) two. 



In the genus Pupilio, Westwood has again figured several species in his 

 ' Arcan. Entom.,' for instance, of the Indian species, P. Glycerion, Gray (pi. 

 55), from Simlah ; Agetes, Westw. (ib.), probably from Sylhet; Astorion, 

 Westw., and Cham, Westw. (Varuna, White), from Sylhet (pi. 66.) In the 

 13th Part a review of the New Holland species is given, and together with 

 P. Aiiactus, Mac L., a new species, P. crtpaneus, Westw., is figured. 



White (Ann. Nat. Hist, xii, p. 262) has made known a new species, 

 P. R'ulleyanm, from the river Zair.
