PEMPELIA CARNELLA. 265 



The pupa is enclosed in a cocoon spun within the 

 hammock, and composed of a coarse dirty whitish 

 silk reticulation of oval form, five-eighths of an inch 

 long. 



The pupa itself is seven-sixteenths of an inch in 

 length, of moderate stoutness, broadest across the 

 thorax and wing-covers, rounded above and sloped 

 suddenly towards the head, which is but little pro- 

 duced, somewhat flattened beneath ; the wing-covers 

 are rather long and close to the body ; the flexible 

 rings of the abdomen taper to a blunt rounded tip 

 furnished with two minute thorny points wide apart; 

 the colour is dark mahogany-brown, darkest on the 

 back of the abdomen, the tip black, the wing-covers 

 and under parts rather lighter brown, the whole 

 surface shining. (William Buckler, 11th October,

Pempelia dilutella. 

 Plate CLIX, fig. 3. 



On the 23rd of June, 1878, I received a larva of 

 JPempelia subomatella from Mr. C. Gr. Barrett, found 

 with two or three more by his eldest daughter and 

 himself at Pembroke amongst Thymus serpyllum 

 spreading its growth over a rock, the larva inhabiting 

 a silken gallery. Of this larva I took my fig. 22 of 

 1878. 



The larva is three quarters of an inch long, slender, 

 •cylindrical, though tapering a little from the fourth 

 segment to the head, which is of roundish character, 

 and tapering still more from the ninth to the end of 

 the thirteenth segment; the segmental divisions are 

 yery well defined, and across the thoracic segments 

 the usual subdivisions are deep, and on each of the 

 •others there is behind the middle a moderately deep
