spiracles, thoracic legs, and claspers red. The 2nd form is similar to the 1st, but with 

 the lon°- hairs bright fulvous. Both forms feed on the same food-plant at the same 

 time, grow to the same size, and produce male and female imagines irrespectively. 



This larva should not be handled without gloves, as its hair penetrates the skin of 

 the hand and causes much irritation. It appears in great numbers in November and 

 early December, feeding on common wattle (Elephantorrhiza burchellii) and also on a 

 species of thorny acacia ; the second brood appearing in March and April. 



The pupa is formed inside a cocoon beset with the hairs of the larva, which cause a 

 very irritating effect to the fingers if it is grasped carelessly, and is affixed to a branch 

 of the food-plant, as shown in the figure. 



Pupee formed in April hybernate in this state, and emerge as imagines in the middle 



of October. 



In common with species of Saturniidse, the male of this moth seems to possess in a 

 hio-h decree the power of discovering the whereabouts of the female, and the possession 

 of one female will enable a collector to secure a large number of males. 



Common and widely distributed in Natal. 



Family LYMANTPJD.E. 



19. Dulichia fasciata (Walker). (Plate XLIX. figs. 13, 14, larva.) 



Larva. Ground-colour velvety black ; dorsal area white, thickly covered with white 

 hairs, except on the 4th, 5th, 11th, and 12th somites, which are surmounted by tufts 

 of long black hairs ; a dorsal red spot on the 9th and 10th somites; a spiracular line 

 of red spots, and below this an interrupted white line bearing long white hairs. 

 Head black ; thoracic legs and claspers red. 



Feeds on species of Bauhinia, and also on rose-bushes and oak, the two latter being 

 imported plants in Natal. 



When ready for its transformation, the larva forms a silky cocoon with its hairs, 

 inside which it changes and remains as a pupa for about 24 days (Dec. 30th to 

 Jan. 23rd). 



Common in gardens in Maritzburg. 



20. Dastchika georgiana, sp. ii. (Plate XLIX. fig. 19, imago ; fig. 20, larva ; 

 fig. 21, pupa.) 



Allied to D. horsjieldii. Head and thorax white; branches of antennae fulvous. 

 Fore wing white, irroratecl with black scales ; the antemedial lines more angled than 

 in I), horsjieldii ; the hind wing white, with some darker hairs on the internal area. 

 Abdomen orange, with a dorsal line of black spots on first four somites. Underside 

 white, no cell-spots.
