PEMPELIA DILIJTELLA. 267 



are slight indications of a third line almost obsolete; 

 the anal flap is wholly black and as a plate rather 

 glistening; the upper lip is drab colour, as also are 

 the papillae but tipped with black; the minute spiracles 

 are black and slightly glistening. 



The larva spins a number of threads on the plant, 

 drawing the leaves together and forming a silken 

 gallery amongst them in which when full-fed it 

 constructs its cocoon and changes to a pupa. 



The pupa is five-sixteenths of an inch in length, of 

 moderate stoutness in proportion, with the wing- 

 covers long and wrapped very close to the body, the 

 eyes large, the abdomen tapering a little, but ending 

 in a blunt tip, having a few excessively minute curly- 

 topped short bristles. Its colour (on the 16th of 

 August) was a light reddish ochreous-brown, the eyes 

 and the tip of the abdomen blackish, the wing-covers 

 the palest portion, a dark blotch on either side of the 

 back on the fourth abdominal ring, and the surface 

 glossy. 



The moth, a ? , came forth on the 5th of September, 

 1879. (William Buckler, September, 1879; Note Book 

 III, 239, 239b, and 271.) 



The larva of Phycis subornatella is noticed by 

 Professor Zeller in the 'Isis,' 1846, p. 768 (translated 

 in the ' Entomologist's Annual,' 1867, p. 144), thus : — 

 " It lives in silken tubes upon the ground amongst 

 the plants of thyme, and is pale with some dark 

 longitudinal stripes." Further than this, I think it 

 has not been noticed or described ; and when, in 1877, 

 I met with one or two specimens of the moth on the 

 coast here (Pembrokeshire), the re-discovery of this 

 larva became a special object of anxiety and search, 

 and considering that the moth is scarce here, and that 

 thyme is most emphatically not so, it will readily be 

 supposed that the re-discovery was no easy matter. 

 However, in the beginning of June, 1878, I visited a 

 spot about thirteen miles from Pembroke, on which one 

 specimen of the moth had occurred, and there on the
