into long silvery streaks. Another curious form has white 

 spots on the upper side, generally irregularly ; but I took one 

 a year or two ago in Surrey, in which the fore wings were 

 symmetrically provided with such a spot, of a triangular shape. 

 May and .June. There is a second brood in August on the 

 Continent ; liut certainly not, except perhaps in the most rare 

 and casual manner, in this country. Indeed, the only actual 

 instance known to me of the occurrence of such an emergence 

 in the United Kingdom happened to myself on the 15th July 

 1868, when I took a single specimen near Haslemere, Surrey, 

 All inquiries fail to elicit other instances. Mr. Herbert Goss 

 assures me that he has looked for a second brood in the New 

 Forest, Hants, for the last twenty years, but absolutely with- 

 out success, although the insect is most abundant there in 

 May and June. In the very forward season of 1865 the insect 

 appeared in the Surrey woods on April 27th, but this was 

 abnormally early. 



Lahva, 1 1 inch long, thickly covered with branched spines 

 pointing slightly backward, except the first sub-dorsal pair, 

 which point rather forward over the head. Head black, beset 

 with short obtuse spines ; body velvety black, with a whitish 

 divided lateral stripe, and a faintly indicated grey sub-dorsal 

 line ; the black dorsal line being indicated only by a grey 

 edging ; sub-dorsal spines greenish-yellow, with tips and 

 branches black, the remaining spines brownish-black ; legs 

 black ; pro-legs brownish at the tips. When younger the 

 lateral stripe is absent, or only indicated as an aggregation of 

 whitish dots on the anterior segments. The larva is hatched 

 towards the end of June, and is at first pale greenish, but 

 after the first moult browner green. About the middle of 

 July it ceases to feed, attaches itself to its food-plant, and so 

 remains during the remainder of the summer, the autumn, 

 and winter. In March bestirs itself, begins to feed, soon 

 assumes its black colouring, and is full fed in April.
