MYELOIS SUAVE LLA. 237 



the segments ; the spiracular region is inflated and 

 puckered ; the ventral legs are much beneath the 

 body. 



The colour of the roughened head is dark brown, 

 with the base of the papillae and a transverse streak 

 above the mouth brownish-grey, the surface glisten- 

 ing ; the plate on the second segment and that on the 

 anal tip are both black and shining; the rest in the 

 young stage rather olive-brown, afterwards becoming 

 deep chocolate-brown ; the skin smooth but without 

 gloss; the ventral legs semi-transparent; the anterior 

 legs spotted with black ; the ocellated spot on the 

 side of the third and twelfth segments is brownish- 

 grey with a black centre, the hair from it being longer 

 than that Avhich proceeds from each of the usual 

 tubercular situations, but all the hairs are alike in 

 being dark brown, fine, and pointed ; the small 

 circular spiracles are of the ground colour. 



By the 19th of June the larvae had spun themselves 

 up amongst the twigs of sloe in greyish silken cocoons, 

 one of which, on the 22nd of the month, I cut open, 

 and found the pupa to be three-eighths of an inch in

 and terminating with seven most minute bristles, 

 curved at their extremities ; in colour it was a deep 

 mahogany-brown, the abdominal divisions darker 

 brown, the whole surface very glossy. 



Four moths were bred on the 19th and 20th of 

 July. 



Another fact in the economy of Bhodophcea suavella 

 remains to be mentioned, that it is not confined to 

 sloe, but is also found on hawthorn bushes, Dr. Wood 

 having taken some larvae from them on a common, 

 which were kept separate, and finally produced this 

 species. He also noticed in the instance of two or 

 three larvae that had been disappointed in pupating, 

 and were wandering about amongst the twigs of sloe, 

 that they had become tinged with greenish, and
