Spilodes PALEALIS. 

 Plate CLIV, fig. 9. 



On the 4th of September, 1875, Mr. W. H. Har- 

 wood sent me several larvae living in cylindrical webs 

 spun within the seed heads of Daucus carota, which 

 were closed up together, affording a good indication of 

 their presence by the closeness of the mass ; the webs 

 of the larvae are just sufficiently large and long enough 

 to contain each larva, and made of light greyish 

 glistening silk, the outer stalks of the umbel being 

 brought up together by a few single outlying threads. 



The smallest larva 1 had was about little more than 

 a quarter of an inch long, of a very pale watery 

 greenish tint dotted with black, and having a black 

 plate occupying only the middle of the second seg- 

 ment. Those larvae that were about half to five- 

 eighths of an inch in length were very much darker 

 than the others, being of a dark slaty greenish colour 

 with their spots conspicuously large. 



The full-grown larva is rather stout in proportion 

 to its length of three-quarters or seven-eighths of an 

 inch ; it is of a plump character, though the segments 

 are deeply divided, and subdivided on the back by one 

 wrinkle ; it tapers a little at both ends, the head 

 closely fitting a little within the second segment. The 

 head is a greenish-yellow in ground colour, much 

 blotched and spotted with black on each lobe and 

 above and at the mouth ; the plate behind it is shining 

 like the head, and has a pale yellow margin in front ; 

 its ground colour is similar to the head, and it is also 

 blotched with black on each side and marked with 

 smaller black spots towards the centre; the ground 

 colour of the back is a light slaty green, lively, but not 

 a bright colour, and the tubercular spots are large for 

 the size of the larva ; these are shining black with a
