that Onobrychis sativa was its food-plant. In August, upon 

 cutting open some of the previous year's stems, I obtained 

 undoubted traces of its work, some of the stems being filled with 

 decaying frass. Successive visits to the locality were paid in 

 September, October, and November, and not till then was I 

 rewarded by the discovery of the larva in the stems near the 

 roots of Onobrychis sativa. Seven larvae were found, which had 

 then apparently ceased to feed, and from them the following 

 description is drawn up : — Length 5 lines, somewhat tapering, 

 the 2nd and 3rd segments being broader than any of the others, 

 the 3rd being the broadest. Colour bright yellow ; head pale 

 yellowish brown ; face with two dark brown lines, which, with the 

 dark brown mouth for base, form a triangle. 1st segment with 

 two indistinctly defined pale yellowish brown plates, anal 

 segment pale brown, dorsal vessel indistinctly pale brown. 

 Spiracles small, pale brown ; legs yellow, prolegs very short, 

 yellow on the 6th, 7th, 8th and 9th segments. On the head and 

 following segment are a few transparent hairs. The larva is 

 active in its movements, progressing very readily backwards. It 

 should be remembered that these larvae may have been full-fed 

 for some time before November, and perhaps have undergone a 

 change in colour. On April 3rd, 1885, a dark brown patch had 

 developed on the anal segment, the larva after its hybernation 

 being somewhat thinner. On June 12th it had changed to 

 a bright yellow pupa within the cocoon which I cut open. On 

 June 25th, first the wing-cases and then the whole pupa changed 

 to a rich dark brown. The imago (female) emerged on July 1st. 

 The egg is probably laid singly and upon the stems of the plant 

 about the middle of July. The larva commences to feed about 

 three parts up the stem and works downward to the root, filling 

 the stem above with pale brown frass. Its presence may be 

 ascertained with certainty by slicing open the stems about half- 

 way up, when the frass will betray it to the collector. Two 

 of the larvae which I cut out closed one end of the stem 

 completely with silk, making at the other a gallery with a small 

 hole for exit. The position of this species in our lists is 

 unsatisfactory, and I am repeatedly asked to say something 

 thereon. Mr. South puts it at the end of Grapholitha, which 

 seems about as bad a place as one could find for it. To enter at 

 any length upon a discussion of this point would involve the
