placed on the side of the last leg. The vent and outsides of 

 the two last legs (right and lefl) are of a very dee|3 pUun- 

 colour. In this change the black rings on the four major 

 fleshy lumps on the head almost fade away, and the caterpil- 

 lar is well covered all over with thin hairs about one-eighth 

 of an inch long : at the base of eacli leg is a yellow spot, and 

 over the mouth are four spots or fleshy lumps forming a 

 crescent. Now comes the fourth change, and the larva is 

 now about two inches long ; the fleshy lumps on the back 

 and sides have changed to reddish yellow, with a black ring 

 on the top of each lump and four black short hairs also : on 

 each side of the light-coloured line on the side of the larva 

 are little reddish yellow spots, and on the line at the base of 

 each leg are diamond-shaped marks, the inside yellow and 

 the outer mark dark red : the legs and under part of the body 

 are or a beautiful dark green, the sides a lighter green, and 

 the back much lighter still and covered with white hairs ; 

 the legs are covered with black hair, and all the fleshy lumps 

 with four or five black bristles. There can be no mistake 

 about the larva 1 have described, for those I have reared 

 have now come out of their cocoons, and the moth is a white- 

 green, with one spot on each wing, two under wings swallow- 

 tailed ; a pink or rather reddish pink line borders the top of 

 the upper wings and crosses the head ; the body covered 

 with white down." 



Mr. Westwood added that Mr. Holdsworth had mistaken 

 the Asiatic Actias Selene for the North American A. Luna : 

 the larva of the Indian species was figured in the fifth volume 

 of the Society's ' Transactions,' from a drawing by Captain 

 Hutton : it was aesirable to see the perfect insect, as there 

 appeared to be several local races of it. 



Mr. Westwood exhibited a series of specimens of Liparis 

 dispar, reared from the egg-state by Mr. Briggs, of St. John's 

 College, Oxford, illustrating not only a remarkable variation, 

 according to the nature of the food of the larva3, but also 

 showing a strong tendency to degeneration. The progenitors 

 of these specimens, two or three generations back, had been 

 obtained wild in Yorkshire, and were of moderate size (not so 

 large, however, as the specimens formerly taken in such 

 quantics at Whittlesea Mere). The eggs were received in 

 October, 1805, and the caterpillars hatched during the first
