22 PYRALIS FALUNALIS. 



lives through two winters, becoming a pupa in May 

 or June of the second year ; and the pupa state lasts 

 about a month. 



The egg is rather long-oval in outline, somewhat 

 flattened, about *65 mm. long, and # 35 mm. wide ; the 

 shell is very thin and soft, finely granulated or 

 wrinkled all over, glistening, in colour dirty white. 



The newly hatched larva is about 1*45 mm. long, 

 with pale brown head, the body dead white, the usual 

 bristles colourless and long. 



The full-grown larva is about 25 mm. long when 

 walking, between 22 and 23 mm. when at rest, stout in 

 proportion, and cylindrical in figure ; the head is 

 small and horny, the second segment, which is rather 

 long, tapering rapidly to it ; the thirteenth segment 

 also tapers away rapidly ; the segmental divisions are 

 well marked ; the folds between the thoracic segments 

 are complicated, as in Aglossa cuprealis, each of the 

 remaining segments with an intermediate fold at 

 about two-thirds of its length from its front edge ; 

 the head is in colour chestnut-brown, very shining, 

 with the mouth blackish ; the second segment is paler 

 brown, rather inclining to yellowish ; the anal plate 

 is also yellowish-brown. The rest of the skin is most 

 delicately shagreened, and in colour bone- white, the 

 belly whiter ; there is, however, a blackish tinge over 

 the anterior and posterior segments, which, throughout 

 the life of the larva, serves (together with its stouter 

 figure) to distinguish it from (Ecojphora pseudospretella 

 and Endrosis fenestreila, which swarm where it is 

 found ; the dorsal vessel is also distinguishable by its 

 darker tint; the usual dots are small and indistinct, 

 surrounded by small pits, and furnished each with a 

 short brown hair ; the trapezoidals arranged (as in 

 Aglossa) almost in squares. Near the front edge of 

 each of the middle segments is a transverse row, 

 interrupted in the middle, of tiny shining fovege, and 

 behind it come short rows set longitudinally near the 

 front pair of trapezoidals, and again near the hinder
