OLEDEOBIA ANGUSTALIS. 43 



kept together by silken threads, which the larvae 

 seem to spin over where they feed. 



The cocoon is shaped somewhat like that of a 

 ZygaBiia, and is formed of finely-spun white silk among 

 the moss. 



The pupa is from half to five-eighths of an inch 

 long, of ordinary shape, and with all the parts clearly 

 defined ; it is highly polished, the colour rich brown, 

 the wing-cases bright yellow, but all the parts 

 margined with brown ; eye-cases and abdominal point 

 dark chocolate-brown. 



The imagos emerged from the 2nd to the 8th of 

 August. (George T. Porritt, October 6th, 1884 ; 

 E.M.M., November, 1884, XXI, 124.) 



Pyrausta punicealis.

For larvae of this species I am indebted to Mr. 

 W. H. Harwood, who found them somewhat plenti- 

 fully last year (1873) on Nepeta cataria; he had 

 previously noticed that the perfect insects were never 

 found far away from that plant, and hence, suspecting 

 that the larvae fed on it, he searched for them with 

 success. 



The larvae (of the second brood) reached me on 

 the 25th of September, 1873, feeding on the mint 

 flower-heads under a confused covering of silken 

 threads, for their work could not be called regular 

 galleries ; and they continued to feed for about three 

 weeks ; then they spun up in very tough cocoons of 

 pale brownish silk, but how long they remained before 

 turning to pupae I cannot say. I bred some moths 

 between the 16th and 23rd May, 1874, yet some little 

 time after this date, viz. on the 11th of June, Mr. 

 Buckler, on examining some of his cocoons in order 

 to obtain a pupa-case, found several larvae still un- 

 changed, though quite alive. Whether these will remain 

 on till the appearance of the August moths of the
