OBSERVATIONS OX BRITISH TINEINA. 59 



Phyllocnistis suffusella, I. B., p. 285. I met with this 

 very interesting larva in great profusion at Micklebam, the 

 beginning of August ; they mined indifferently the upper or 

 underside of the leaves of the aspen (Populus tremula). 

 The mined leaves show no distinct track, as the larva eats 

 only the juice by which the skin of the leaf is fastened to the 

 parenchyma, but when we view the leaves at an angle they 

 appear shining and reflect prismatic colours, as though a 

 snail had crawled across them. 



BuccuJatrix aurimaculella, I. B., p. 291. I had the good 

 fortune to signalise my first evening "across the channel" 

 by finding the larva of this species at Boulogne, April 17th ; 

 it feeds on Chrysanthemum leucanthemum (ox-eye daisy), 

 when young mining the leaves, afterwards feeding on them 

 externally; it makes a ribbed whitish cocoon. Bucculatrix 

 nigricomella, not hitherto found in this country, feeds on the 

 same plant and at the same time. 



Bucculatrix cidarella, I. B., p. 291. We have found 

 the larva of this species feeding on alder leaves in July, but 

 hitherto we have not succeeded in rearing it. 



Nepticula angulifasciella, I. B., p. 304. By keeping the 

 collected larvas of this species out of doors all the winter, I 

 succeeded in rearing a fine series of the perfect insect ; they 

 made their appearance from the 13th to 28th of July, a suffi- 

 cient proof that the insect is only single-brooded. 



Pterophorus acanthodactylus. Mr. Reading, of Ply- 

 mouth, has met with the larva? of this species on rest-harrow 

 {Ononis), and forwarded me several of them, at the be- 

 ginning of August. Hiibner's figures of P. Calodactylus 

 well represent the larva and singular pupsc of this species. 

 This is an addition to our information, for in the Zoologist, 

 j). 4775, in the Entomological Botany, under Ononis spinosa 

 I called attention to the fact of the larva of this species not 

 having been found on that plant.
