from the head to the anal claspers ; its colour is pink, narrowly bordered above and 

 below with pure white : the spiracles are also pure white, delicately bordered with 

 black: belly, legs and claspers pure olive-green. Such is a description of the more 

 usual or normal colouring of this pretty larva, but neither of the colours seems abso- 

 lutely constant, except those of the subspiracular stripe ; the upper stripe is sometimes 

 entirely wanting, and the dorsal surface varies from the normal opaque green to bright 

 apple-green, to pink, to clear brown, and to deep olive-brown : it is full-fed at the end 

 of August, and changes to a smooth brown pupa below the surface of the ground, 

 remaining in that state until the following June, when the perfect insect emerges. —

The so-called Mine of Lithocolletis. — T was somewhat surprised to see my commu- 

 nication (Zool. 8648) headed " Mine of Lithocolletis Larvae mounted as Transparent 

 Objects on Card-board." As I had intended the plan for every description of mine, I 

 was still more surprised to see that you had mistaken the common Nepticula aurella 

 for a Lithocolletis, but I let it pass unheeded till Mr. M'Lachlan's remarks (Zool. 

 8734) called for an explanation. Mr. M'Lachlan will observe that I merely said in 

 my communication the plan " would do " for Lithocolletis mines. I am still inclined 

 to think card-board less cumbrous than glass, and paper (which I generally use) still 

 less so than card-board. — H. W. Kidd ; Haslemere, September 4, 1863. 



[I am quite willing to acknowledge my mistake. Mr. Kidd's mentioning the genus 

 Lithocolletis must have given me the idea. The title of all communications should 

 he given by correspondents : it not only avoids the risk of error, but it saves me an 

 infinity of trouble. I am sure Mr. Kidd will kindly oblige me in this matter iu future 

 communications. — Edward Newman.']
