380 PTEliOPHORUS TETRADACTYLUS. 



The ground colour is bright pea-green, when 

 younger (i. e. previous to the last moult) having a 

 yellowish tinge ; the head is yellowish-green ; the 

 mandibles and a spot on each side of them are 

 brown ; the broad dorsal stripe is of a considerably 

 darker shade of green than the ground colour, and is 

 powdered on each side with greyish- white ; the sub- 

 dorsal stripes are of the same dark green colour, but 

 not so conspicuous ; the spiracular stripes are rather 

 broad, yellowish-grey ; the segmental divisions and 

 hairs are white. When younger the segmental 

 divisions are yellowish-grey, and the hairs are grey. 

 The ventral surface, legs and prolegs, are uniformly 

 of the bright pea-green of the dorsal area. 



I bred no imagos, as the larvse came to grief during 

 my absence in London ; but in this case it did not 

 much matter, for Mr. Bankes having fortunately 

 reared the imago from a similar larva the previous 

 year, had thus made sure of the species. Apart from 

 that, they were too large for P. jparvidactylus, the 

 other thyme-feeding species, which, moreover, Mr. 

 Bankes believes does not occur in the district.

On the 4th of July of last year, 1881, I received 

 eggs of this species from Mr. W. H. B. Fletcher, 

 deposited by a moth he had taken at Worthing. Five 

 days later they hatched, and the newly-emerged larvse 

 were white, and clothed with long white hairs. They 

 fed for a short time on convolvulus, but hibernated 

 early, when still very small. In April they recom- 

 menced feeding, but by the 15th were only a little over 

 a quarter of an inch in length. From that time they
