CRAMBUS CULMELLUS. 295 



the plate on the second segment bears a few minute 

 black-brown dots and a larger pair on the hind 

 margin ; each tubercular spot bears two dots of 

 darkish brown, one small, the other larger, furnished 

 with a fine hair; the minute spiracles are round and 

 black. 



It travels forwards or backwards equally well, and 

 from the middle of June converts its tubular residence 

 into a cocoon of oval shape from three-eighths to half 

 an inch longest diameter, smoothly lined with pale 

 grey silk and externally covered with frass or with 

 particles of moss, or with both. 



The pupa is three-eighths of an inch long, of the 

 usual contour, but rather plump ; the head and thorax 

 are moderately produced, the form tapering very 

 slightly towards the widest part of the body at the 

 ends of the long wing-covers ; from thence the abdo- 

 men tapers a little more towards the rounded-off tip, 

 ending with a rather prominent boss ; in colour it is a 

 light warm shining brown, the lower part of the 

 wing-covers paler brownish-yellow, the terminal boss 

 dark brown. (William Buckler, 12th August, 1880 ; 

 E.M.M., September, 1880, XVII, 91—93.) 



Crambus pedriolellus. 

 Plate CLX, fig. 6. 



Thanks to Mr. Charles G. Barrett's researches at 

 the Yarmouth denes, and his kindness in supplying 

 me on the 11th of last June, 1870, with several 

 examples of the larvae, and subsequently with their 

 curiously constructed cases and cocoons containing 

 pupae, I am able to offer the following account of 

 Crambus fascelinellus (pedriolellus). 



The larva is from five-eighths to three-quarters of 

 an inch in length, moderately stout and cylindrical, 

 but tapering a little just towards the hinder extremity ; 

 all the segments are plump and well defined.
