diftinCt, and well relieved with fufcous, and ferruginous. In our in- 

 fect the general colour is pale rufous (lightly tinged with fufcous in 

 the area of the wing, and varied towards the circumference with deep 

 fulvous : the denticulated bands acrofs are dilpofed in a fimilar man- 

 ner to thofe on the wings of Bombyx Dromedarius, but are of a yel- 

 lowifli inftead of whitiQi colour, and nearly obfolete. So far as our 

 own obfervation extends there is a difference alfo in the pofterior 

 wings : in our Bombyx Zebu thofe wings are of a very pale fufcous 

 with only a fingle fainter band ; in Bombyx Dromedarius the wings 

 are paler ftill ; it has likewife a fimilar band, but which is rather 

 more denticulated, and being bounded both above and below with a 

 dulky band, the wings appear of a lighter colour next the pofterior 

 margin, and in the diilt of the wing ; the latter part has alfo a fingle 

 ihort transverse dafh of a duiky colour. A further difference is ob- 

 fervable in the lower furface : the general tint in our B. Zebu is pale 

 ferruginous; in B. Dromedarius greyifh, with the lower pair whitiih, 

 and in both, the bands confpicuous ; the tip of the anterior pair in B. 

 Zebu teftaceo-fufcous, in B. Dromedarius diftinctly grey; and the 

 central fpot in the lower wings of the latter fufcous with a white 

 fpeck in the center, but in B. Zebu plain teftaceous without any 

 central mark. 



In the " Lepidoptera Britannica" Mr. Haworth defcribes our 

 Bombyx Zebu as a fpecies perfectly new, under the name of Bombyx 

 Dromedarulus. The fpecimens from which his defcription is taken 

 were thofe in the cabinet of Mr. Drury, and which are now in our 

 poffeffion. This infect was probably new to the Aurelians of this 

 country, but certainly not fo to the continental entomologifts, and thofe 

 mould affuredly have beenconfulted previoufly to its being defcribedasa 

 nondefcript infect. In the works of Emit which this ingenious writer 

 has overlooked, will be found a figure both of the upper and lower fur- 

 face of the infea from a larger fpecimen than our own, and tolerably 

 expreffive; and with a defcription of the infea equally fatisfactory. 

 It appears from thence that the figures are copied by Eraft from a 

 female fpecimen in the noble colle^on of M. Gerning, of Frankfort,
