12 THE entomologist's RECORD. 



never wholly entering its mine except when it is making a larger one, 

 from which to cut out a new case. It is extremely fond of the smaller 

 leaves and leaflets, and rarely makes more than one small round, or 

 nearly round, blotch in each. One may look over quite a number of 

 twigs, with several leaflets on each, disfigured by these blotches, before 

 meeting with the culprit. The terminal portions of the twigs are 

 preferred, probably because there the pabulum is more succulent. 

 Normally the cases of this species are three-valved, but two of the cases 

 when fully completed, possessed only two valves to the anal opening. 

 The larv£e obtained from Ashtead had all finished feeding by May 

 30th, and had moved away to a fresh unblotched leaf, or to a 

 stem, to which they had very securely fastened their cases. The first 

 emergence from these cases was on June 30th, exactly a month from 

 the time of fixing the case to prepare for pupation. I should like to 

 record that, at Sanderstead, I found a larva of this species feeding on 

 crab -apple. 



CoLEOPHOKA coNYZiE. — For this very local species I am indebted to 

 the kindness of Mr. Eustace Bankes, of Corfe Castle. On April 26th, 

 1904, I received a very nice batch of larvffi just taken by him in the 

 Isle of Purbeck, feeding on Inula conyza. In his letter, Mr. Bankes 

 says that C. conyzae is rarely found on I. dyseyiterica, but two or three 

 of the larvffi sent had been found on that plant. He stated that this 

 species was " extremely local even in its favourite haunts," and " most 

 capricious in its appearance ; it may be common one year, and then 

 one may see little or nothing of it for several years afterwards." He 

 pointed out the fact that C. conyzae is one of those species which does 

 not enlarge its case, but cuts out a new one when it requires it. Thus 

 it happens that for every larva taken one always meets with several 

 empty cases. He goes on to say, " A careful examination of the leaves 

 and stems will shew you some very small blackish cases, wdiich are the 

 earliest cases of C. conyzae. Some of these are doubtless empty by 

 now (April 25th), but a few of them are certainly still tenanted, and if 

 you do not see the larvs, you can pretty well decide whether the case 

 is tenanted by the freshness, or the reverse, of the appearance of the 

 mined blotch." Among the cases received were, as Mr. Bankes said, 

 a number of these little, blackish, cylindrical cases, most of them 

 abandoned, and situated as a rule near where a case had been cut out. 

 The small cases containing larv^ were chiefly attached at or near the 

 tips of the leaves, and frequently there were two on a leaf. After con- 

 siderable search I found a favoured spot at Ranmore Common, where 

 an Inula was growing in quantity, but, unfortunately, I did not know 

 /. conyza sufiiciently well, and after my larvae had nibbled and 

 dwindled, I found that the plants I had secured were /. dysenterica, for 

 which they have but little liking. Thus all of the larvae were dead or 

 pupated by June 8th, and the only one bred emerged on June 30th. A 

 considerable number of the larvae produced parasites, quite in accord 

 with what Mr. Bankes has stated elsewhere, that when any of the 

 species are abundant in any year in the larval stage, it very frequently 

 happens that by far the larger number fall victims to ichneumons, etc. 

 The following is a description of the larva : — 



The 1st thoracic dorsal plate is very large, covering so much that it leaves only 

 a small margin of larval skin around it. It has no division down the middle. 

 Head plates are all intensely black. The mesothorax has an oblong dorsal plate
