EPHESTIA INTERPUNOTELLA. 215 



The pupa was a little less than three-eighths of an 

 inch long, of the usual form, the head and eye-pieces 

 and antenna-cases rather large, the abdomen pale 

 brown tinged with honey-colour. 



No moth was bred from these, but on the 18th of 

 April, 1874, Mr. Barrett forwarded me six larvae of 

 Plodia interpunctella, just the same as those above 

 described, which he had found last summer about 

 locust-bean sacks " most commonly," and in confine- 

 ment they ate the beans freety. 



These larvae became from three-eighths to half an 

 inch long by the end of June, and spun themselves up 

 amongst the grains of malt on which they had been 

 feeding. 



The perfect insects appeared on the 17th and 20th 

 of July, and the 1st and 19th of August, 1874. 



The cocoon is formed with light brownish-grey silk, 

 sometimes with particles of frass or the white interior 

 of broken malt-corns, or both, adhering to its surface, 

 Avhich was spun amongst a web which united a number 

 of malt-corns together. The cocoon is of an irregu- 

 lar elongate form, varying from half an inch to nearly 

 five-eighths in length, and more than two lines in 

 diameter, nearly fusiform, but more pointed at one 

 end than the other, at which the head of the pupa is 

 directed. 



The pupa itself is three-eighths of an inch in length, 

 rather smooth, of ordinary form, and tapering a little 

 to the rather rounded tip, which ends in a few most 

 minute bristles, only visible with a powerful lens. 

 Its colour is a pale brown. (William Buckler, August, 

 1874; Note Book I, 184.) 



On the 21st of December, 1878, I received from 

 Mr. J. R. Well man, of London, larvae of two species, 

 supposed at the time to be Ephestiae, feeding on dried 

 figs; from the one described below Plodia interpunctella 

 was bred. 



Length about five-eighths of an inch, cylindrical, 

 and of average bulk ; the head polished, the lobes
