174 THE entomologist's eecord. 



keel, in C. olivaceeUa, goes very distinctlj^ from just behind the mouth, 

 right up to the suture of the two side valves of the anal opening. 

 There is no back keel, but two very slightly developed ridges rise in a 

 point just at the commencement of the straight portion behind the 

 head- bend, and diverge gradually till they join in the sutures of the 

 side valves, with the third valve of the anal opening. There seemed a 

 tendency for the brown coloration to become streaky longitudinally, 

 but this was obscure, and may have been only an individual character- 

 istic. The mouth was very oblique, which made the case almost prone 

 on the grass leaf. In C. solitanella, the case is almost upright to the 

 surface of the grass. On May 16th, I noticed the larva with its head 

 in a hole bitten completely through a blade of grass, and feeding 

 away on the edge without mining, just as if it were an ordinary macro 

 larvaB. By the middle of June it had finished feeding. But later on 

 I found a round hole bitten through the case, a sure sign that a 

 parasite had emerged, instead of the much wished for lepidopteron. 



CoLEOPHORA LiNEOLEA.- — A Walk dowu the dusty Bromley Road, 

 below Catford, and a search among the Ballota nigra growing along- 

 side under the shelter of the elm bushes and trees, produced plenty of 

 the larva and cases of (.'. lineolea. This species, I may note, is 

 particularly fond of the neighbourhood of very dusty roads, and I 

 met with it in such a situation at Crofton Park, Chatham, and Sander- 

 stead, last year. The following notes were made on the larva : — 



The prothoracic segment with a black shield covering the whole of the upper 

 surface. This plate has an irregular margin of brownish all round, showing more 

 prominently along the front edge. A thin pale sutural line down the middle of the 

 back, widening somewhat towards the rear, divides the shield into two plates. 

 The mesothoracic segment has two black plates on the back, separated down the 

 middle of the back by a sutural light line, perceptibly wider than the widest 

 portion of the sutural line on the 1st abdominal segment. These plates are roughly 

 triangular, with the ajoex outwards, and reaching about half way across the segment. 

 The metathoracic segment has two small circular black plates on each side of the 

 back, somewhat nearer to the centre line than to the outer side of the back. All 

 three segments have a similar equal-sized black plate on the projecting portions of 

 the sides. Those on the mesothorax, which projects somewhat more than the other 

 two, are slightly the larger. Of several larvae examined, one or two had a small 

 black plate on the outer sides of one or more pairs of the prolegs. The head is 

 light brown, blackish to black towards the sides and back. 



On May 21st, I had no Ballota nigra, and offered the larvae Stachys 

 sylvatica. This they fed on quite as well, and after that, the larvse I 

 had, were given both plants. On May 29th, this species Avas found in 

 the larval state in plenty at Chatham, and Mr. Bacot took some at 

 Broxbourne, on May 30th. Mr. South also reported finding the larva 

 on Stachys sylvatica, and, on June, 11th, at Sanderstead, I met with 

 them on the same plant. On June 15th, many of my larvae were 

 still feeding, but by June 20th, all had spun up for pupation. The 

 emergences occurred in mid-July. 



Butterflies in Switzerland in 1905. 



By J. N. KEYNES, M.A., D.Sc, F.E.S. 



I spent August, 1905, in Switzerland, with my wife and family, 



the entomological members of the party being my younger son and 



myself. Our stopping-places were selected to a large extent with 



reference to their entomological potentialities, and until nearly the end
