290 CRAMBUS DUMETELLUS. 



The larva itself was five-eighths of an inch or a 

 trifle more in length, of a moderately stoutish figure, 

 and having the usual large shining finely wrinkled 

 spots of very dark brown on a dull smooth brown skin 

 rather paler (all Vandyke brown) ; those on the back 

 are very close together, divided only by a fine dorsal 

 line of flesh-colour, each spot with a fine dark hair, 

 the first dorsal pair of each segment transversely 

 squarish but rounded off, the second pair transversely 

 linear; beneath on the side the anterior spot is some- 

 what triangular, the hinder one narrow and drop- 

 shaped ; those below are longitudinally rather linear- 

 ovate; those on the side of the thoracic segments 

 are drop-shaped, those above on the back of those 

 segments linear as in Xylophasia polyoclon ; the 

 spiracles are small, round and black; the plates on the 

 second and the thirteenth segments are warm dark 

 shining brown ; the thirteenth segment on its front 

 portion has the two spots soldered together into one 

 transverse spot, so characteristic in this genus; the 

 head is dark shining brown. All were figured with 

 Vandyke brown on the 16th of May. 



The cocoon is less than three-eighths of an inch in 

 length, oval, of brownish-grey silk formed at the end 

 of a gallery. (William Buckler, 1879 ; Note Book III, 

 100—101.) 



Crambus sylvellus. 



In August, 1880, Mr. W. H. B. Fletcher found 

 Crambus adipellus (sylvellus) swarming in a bit of 

 boggy ground in the New Forest, and on the 19th I 

 received a few eggs from him. They were deposited 

 loosely, and were of a dull creamy white colour. 



They hatched out on the 28th of August, the 

 newly-emerged larvae being white, with reddish head.
