more or less covered with white secretion. <? . Scale of the usual 

 shape, rather broad, with a barely indicated median keel ; exvivia 

 bright orange. 



? . Dark brown, subpyriform, or rather club-shaped, the anterior 

 end being much narrowed ; median lobes rounded, very low, rudi- 

 mentary, but conspicuous because of their dark colour ; two other lobes 

 barely iudicated by low rounded structures ; spines ordinary ; squames 

 long and spine -like ; anal orifice far from the hind end ; five groups of 

 circumgenital glands, the posterior laterals about 10, anterior laterals 

 about 8, median 6 ; submarginal region with large reticulated patches, 

 transversely elongate, making the five posterior segments, the last pair 

 lougitudnially elongate, and situated about the region of the lateral 

 circumgenital glands ; mouth -parts large. 



? . Second skin. Mouth-parts between the anus aud the hind 

 margin of the body ; median lobes large, quadrate, separated by a 

 rather wide interval ; margin on each side of median lobes strongly 

 serrate ; squames long and spine-like. Some individuals of the third 

 stage, presumably not quite mature, show also the large quadrate 

 median lobes, with wavy-ti-uncate ends. 



Hah. Durban, Natal, on native shrub (Fuller, No. 18). Also 

 found by Mr. Fuller at Verulam, Natal. C. retigera, as its name 

 indicates, is peculiar for the net-work areas. Mytilaspis dcfccta, 

 Maskell, has similar structures, and may be more closely allied 

 than the different generic reference would suggest.

NOTES AND OBSEEVATIONS. 



On Kearing Lasiocampa (Bombyx) quercus. — The subject of rearing 

 hybernating larvae has lately been attracting some attention, so my 

 experience perhaps may be of interest. .On August 15th, 1900, I had 

 a female L. (IJ.) qi(erciis brought to me, together with about forty eggs 

 that she had laid. These hatched on September 9th and 10th. The 

 young larvffl were supplied with bramble, so that they could be fed 

 during the winter if they should need it. They ate fairly well, but 

 grew very slowly, changing their skins for the first time between 

 September 21st and 27th, and again in the middle of October ; early 

 in November they ceased feeding. During the winter I kept them on 

 bramble twigs, which were stuck into pots of damp earth, covering 

 the whole with a glass bell, open at the top. This I placed in the 

 window of a room at the top of the house, where it could get no 

 artificial heat, though, of course, the air inside the glass bell was 

 warmer and moister than the normal atmosphere of the room. A 

 large number died during the winter, especially towards the spring; 

 the remainder, nineteen, began crawling about again at the end of 

 February, and as the new leaves were not then out I had to feed them 

 on the old ones, which three of them seemed too weak to eat, and died. 

 The rest, however, commenced to feed fairly well, and moulted after
