dirty whitisli-green, narrow, and slightly interrupted line, 

 and then another darker, broad stripe of blackish-green, 

 along the lower edge of which are the black spiracles. A 

 double whitish stripe follows extending down the sides of 

 the anal prolegs, produced by a line of pale dirty greyish- 

 green running through the middle of the white ; under 

 surface and prolegs greyish-green ; ordinary shining warty 

 spots black ; head greyish-brown, mottled and streaked with 

 black ; a dark brown shining plate on the back of the 

 second segment is divided by three paler greyish lines. Some 

 of these larvae present great resemblance to several of the 

 varieties of that of A. tritici ; but the double white stripe 

 above the feet, and the black warty dots, give distinct 

 characters to the larva of the present species. (W. Buckler.) 

 September to the middle of June, on clover, plantain, 

 Heradcum sphotuhjlium and other Uiiibdlifcrcv , and almost 

 every description of low growing weeds in cultivated fields, 

 but apparently not on any grasses. Mr. Buckler's remarks 

 on this subject are of great interest. " On May 11, 1865, 

 Mr. H. Doubleday sent me some larva3 vrhich proved to be of 

 this species, and to that gentleman I am indebted for the 

 following account of their destructiveness in a field of ten 

 acres, which in the previous autumn was sown with wheat 

 and with clover in the early portion of that year. The 

 clover came up well and the field was green all over with it, 

 until these larvae began to attack it. So prodigious were 

 their numbers, and so great their power of devastation, that 

 by the 1 7th of May not a leaf of clover nor of any weed 

 remained upon the whole ten acres, though the wheat was 

 uninjured, and by that time they had left the open field and 

 gone to the hedge-banks and ditches where a remarkable 

 scene of destruction presented itself to view ; the large 

 Heradcum and other umbelliferous plants were stripped of 

 their leaves, and in short nothing was left but grasses, which 

 they did not appear to touch. I received other larvas on the 

 14th of May from Ipswich, feeding on Plantayo major and
