Plate CLX, fig. 13. 



In July, 1884, Mr. Nelson M. Richardson sent me 

 a supply of eggs of G r ambus perlellus, obtained from 

 a moth or moths he had taken in the neighbourhood 

 of Llangennech, Carmarthenshire. 



They hatched in the third week of the same month, 

 the newly-emerged larvae being yellowish-green, with 

 a red longitudinal vessel or stripe showing through 

 the skin, which gave them a salmon-coloured appear-

 of an inch long. Four days later, on the 12th, I saw 

 them again, when they were still only about the same 

 length. The ground colour varied from dingy olive- 

 brown to dirty purplish-brown, the skin in all cases 

 being so transparent that the internal alimentary

 varied from pale brown with darker marks to very

 was paler and greener. 



From this time they evidently hibernated, and I do 

 not know at what date they recommenced feeding in 

 the spring. 



By the 25th of April they were about three-eighths 

 of an inch long, and of the usual Gr ambus form. The 

 ground colour was light mahogany-brown, the tuber-
