216 EPHESTIA liNTERPUNCTELLA. 



rounded, and the mandibles prominent ; it is slightly 

 narrower than the second segment; adjoining the 

 head, on the second segment, is a semicircular polished 

 plate ; the skin has a flabby translucent appearance. 



Body almost uniformly a very pale straw-colour, the 

 alimentary vessel showing through the skin, forming 

 the darker medio-dorsal stripe ; the head and plate a 

 warm sienna-brown, and the mandibles and the tips 

 of the prolegs still darker brown. There are no other 

 noticeable markings. 



These larvae lived on, apparently not increasing at all 

 in size, and rarely feeding, until June following, when 

 loose silken cocoons were formed under the edges at 

 the top of their glass cylinder ; and an imago appeared 

 at the end of the month following. (George T. Porritt, 

 5th March, 1880; E.M.M., April, 1880, XVI, 261.) 



Ephestia artemisiella. 

 Plate CLVII, fig. 1. 



My friend Mr. D'Orville has for some years culti- 

 vated various plants in his garden with the sole object 

 of attracting Lepidoptera, either in the imago or in 

 the larva state, and with some considerable success. 

 Amongst other species, Ephestia artemisiella has been 

 a more or less constant visitor, inducing at last the 

 belief that it was bred in the garden ; and lately Mr. 

 D'Orville has been able to prove this to be the fact, 

 and now desires me to put together some account of 

 his investigations. 



The egg state has not been observed ; but pro- 

 bably the eggs are laid low down near the ground, 

 on the rough woody stalks near the roots of Artemisia 

 absinthium, as it is here generally, in old plants, that 

 the larvae are found to have made their entrance, and 

 excavated mines or chambers for themselves while 

 feeding on the central substance of the root-stalks, 

 much after the manner of some of the Sesiidse.
