 wrapped it up. (J. EL, 8, 9, 70 ; E.M.M. VII, 99.) 



Trochilium chrysidiforme.

On the 19th of August, 1880, I received from Mr. 

 W. H. Jeffrey five eggs laid by an unimpregnated $ 

 of this species. These were the first eggs I had seen 

 of any of this genus. The egg was comparatively 

 large for the size of the moth, of a broad oval shape, 

 flattened, and with a hollow longitudinal depression 

 above and below (that is, on both sides of the flattened 

 egg) ; the surface was apparently smooth and shining ; 

 it was of a very dark purple-brown colour. (W. B., 

 Note Book II, 27.) 



On the 5th of July, 1866, I received from Mr. 

 Meek the larva of this species feeding in the roots of 

 Bumex aeetosa and some other kind of Bumex, he 

 having observed and followed a female moth and seen 

 her deposit her eggs on several of the above plants ; 

 with great sagacity he followed up his discovery by 

 detecting the larvaB, one of which I have now the 

 pleasure to describe. 



This larva had mined in the thickest portion, and 

 rather on one side of the root ; it had ejected heaps 

 of brown " frass" at both ends of the mine, and had 

 spun a tough brown silken covering over a portion of 

 the side which had been eaten quite through; this 

 and the " frass " were good indications of the tenant 

 within. 



The larva was from, five-eighths to three-quarters of 

 an inch in length, tapering a very little posteriorly ; the 

 head was rather broad and slightly flattened ; the body 

 rather pellucid, smooth, plump and shining. 



In colour it was of a dirty brownish- white, with the 

 dorsal vessel showing through as a dark grey internal
