332 DEPRESSA1UA BADIELLA. 



In confinement, without earth with the plants, its 

 gallery of silk becomes covered with accumulations 

 of " frass." 



Often when the larva attains the last moult we see 

 the dark dingy olive-green variety, with belly rather 

 lighter than the back, the one colour blending with 

 the other ; the spiracles round and black, are very 

 minute and situated nearly close below the single row 

 of dots on the side ; the pale yellowish margin of 

 skin next to the head, in front of the plate on the 

 second segment, is a good and constant character. 



The pupa is generally enclosed in a cocoon, covered 

 with grains of earth, of oval shape, 18 mm. in length, 

 rather loosely held together with but very little silk 

 in the lining of brownish-grey colour, the interior of 

 cylindrical form and smooth, 12 \ mm. in length, so 

 that the pupa, which is only 10 to 11 mm. long, has- 

 plenty of room. 



The pupa is rather slender in the S > stouter in the 

 ? ; it has nothing remarkable in its form save that 

 beyond the wing-covers, the abdomen tapers gradually 

 in the <$ , more obtusely in the ? , and the moveable 

 rings are deeply cut ; the tip of the abdomen is sur- 

 rounded with about twelve exceedingly minute curly- 

 tipped bristles, which take a firm hold of the silk 

 lining. 



One pupated openly on the surface of the earth, 

 attaching its tail to a leaf of the plant, and this- 

 enabled me to see that for some time its colour was of 

 a light greenish-ochreous ; afterwards it was light, 

 brownish, and still later it turned very dark brown ; 

 it was glossy from first to last. 



The moths were bred on the 11th, 12th, and 17th 

 of August, and the 13th of September, 1883. (William 

 Buckler, September, 1883; E.M.M., June, 1884, 

 XXI, 3—5.)
