' Entomologist :' the possession of a liberal supply of the 

 larvae has enabled me to verify Boisduvars admirable de-

Descriplioii of the Larva of Pempelia formosella. ■ — It 

 usually spins a very slight web for a dwelling-place among 

 the leaves of the elm, on which it feeds, but this is little 

 more than a few threads, and even these are sometimes 

 absent: it moves forward by a continuous series of jerks, 

 entirely different from the geometric progress of the loopers 

 or the business-like crawl of the Noctuas : when annoyed it 

 falls from its food-plant, hanging by a thread ; the head is 

 porrected on the same plane as the back ; the face is very 

 flat ; the body is scarcely cylindrical, being somewhat flat- 

 tened on the ventral surface : the colour of the head and 

 body is olive-green, with eight very slender, whitish and 

 rather indistinct stripes extending its entire length, and there 

 is a circular white spot on each side of the 3rd segment. It 

 was full-fed and turned to a pupa at the end of July. I am 

 indebted to Mr. Goosey, of Stepney, for a supply of this 

 larva. — Id. 



Observalions respecting the Economy and Pupation of 

 Tinea bisellle I la, Hemm. — This little domestic pest I find, 

 according to my experience, does not, when very young, 

 spin any covering or " run " in which to secrete itself, but 

 feeds openly : it is much alarmed when brought in close 

 contact with a lighted lamp, &c., and scampers off" as fast as 

 it can travel from the immediate neighbourhood of the object 

 of its terror. The larva? appear to be more luiraerous in the 

 month of May than at any other period of the year. The 

 young larva is of a whitish colour, mouth dark brown, head 

 light brown, dorsal vessel somewhat darkish ; after the lapse 

 of a few days the head assumes a darker brownish tint, and 

 the hind lobes of the same have a faint indistinct darkish 

 look ; the dorsal vessel is darkish, but not of an uniform 

 colour, having a clouded appearance in several places ; the 

 hind lobes of the head become deepened in tone ; the dark- 

 coloured dorsal fluid becomes disconnected, and finally 

 settles in the vicinity of the last segments, where its presence 

 IS made known by a dark blotch appearing in that region. 

 Generally about this period of its life the larva moults for the 

 first lime : its method of moulting consists, first of all, in
