282 PKM TELIA DAVISELLA. 



the approach of winter, when each forms for itself a 

 close cocoon or tunnel of silk in which to hibernate. 



In early spring the larvse lengthen these cases, and 

 extend, as they increase in size, the silken web,, 

 feeding on the young buds and blossoms beneath it. 

 On fine clays they may be seen sunning themselves on 

 the outer part of the web, but they retreat into their 

 tunnels on the least alarm. The little companies of 

 larvse are very abundant in this district in winter and 

 spring, and as the summer advances form conspicuous 

 objects on the furze bushes. The larvse cannot be 

 dislodged by beating, and it is only by pulling their 

 nests to pieces that their presence can be detected. 



The imago is figured in Morris's ' British Moths ' 

 as P. palumbella, and under that name I have had it 

 in my collection for several years. (H. Moncreaff;. 

 Entom., June, 1874, VII, 132*.) 



Pempelia palumbella. 



On the 7th of July, 1883, Mr. W. H. B. Fletcher 

 sent me about fifty eggs laid on small terminal sprays 

 of Galluna vulgaris, by no means easy to detect. 



The egg is in shape a long elliptical figure, covered 

 all over with fine pitting, slightly glistening, and of a 

 dirty greenish tint ; by the 12th the eggs had become 

 quite green, and matched well the slight withered tint 

 of the heather spray they were laid on, and were now 

 more difficult to discern than before. 



On the 15th, at 8.15 p.m., three larvae were hatched,, 

 and soon after were placed on sprays of Galluna vul- 

 garis; twenty-one more were hatched by next morning 

 (the 16th), three more in the afternoon, and in the 

 evening as many as twelve, and three more on the 

 19th, two more on the 21st, and one on the 22nd. 



The newly-hatched larva is of a dull brownish- 

 green colour, with very dark brown head and a less 

 dark brown plate on the second segment, and fine
