CRAMBO'S CONTAMINELLUS. 303 



them into very tough cocoons smoothly lined with 

 brownish-grey silk, and externally coated with fine 

 earth and frass. 



The moths, and a couple of ichneumons, were bred 

 from the 17th of Julv to the 7th of August. 



This season I have again found a few of the larvae, 

 and have been able to verify and extend last year's 

 observations, so that I can now say that in early 

 spring the larva is not more than three-sixteenths of 

 an inch long, the body of an earthy reddish-brown 

 with darker brown head, the spots and plates of the 

 same colour as the body, but contrasting by their gloss 

 alone. After each moult the colour becomes greyer 

 as they advance in growth, and when full-grown the 

 larva measures a little more than three-fourths of an 

 inch in length, and is moderately slender, yet the 

 segments have a certain characteristic plumpness in 

 detail from their being well defined, and each is sub- 

 divided with a deep transverse wrinkle between the 

 trapezoidal spots of the back ; the rather rounded 

 head is a trifle less than the second segment, which is 

 long in proportion, and the body tapers a little just 

 towards the hinder part ; in colour the head is greyish- 

 brown marked with blackish-brown ; the plate behind 

 it is similar, and both are shining ; the body is lightish 

 dull earthy-grey with a rather darker dorsal line; the 

 spots are lightish brown and glossy, the larger trape- 

 zoidal pairs transversely roundish-ovate, the smaller 

 pairs rather linear and each encompassed with a faintly 

 paler outline ; there is a row of somewhat trilobed 

 spots along the side, and under them the small round 

 black spiracles, and beneath them again other rows 

 of paler and longitudinally-ovate spots ; every spot 

 having within it, nearer the outer margin than the 

 middle, a small black dot bearing a fine hair; on the 

 front part of the thirteenth segment the two spots are 

 united into one larger than usual; a few minute dark 

 dots are on the shining anal plate ; the ventral and 

 anal legs are tipped with brown hooks.
