In de Peyerimhoff's account of the species in Milliere's Tcono- 

 graphie, vol. iii, p. 220, there is nothing to correct, except thai he 

 says the hind-wings have no scales, only hairs. The scales of the hind- 

 wings are not very narrow, but are apically pointed, having a spindle- 

 shaped outline, beyond the middle of the wing they are however 

 broader, and have two, three, and even four teeth, but are not quite so 

 broad as on the fore-wing. 



Perhaps one might correct also the statement that the larva- does 

 not close the case when it retires for pupation, this is not so, it lightly 

 spins together the anterior opening, closes the posterior end firmly, 

 and attaches the case by a few short thick cables to whatever it lies 



against. 



He also speaks of the egg as being laid on the leaf, whereas as a 



matter of fact, it is laid in it. 



The cases are found at Cannes, wherever Oistus salvifolius grows 

 in suitable shaded places, and it especially affects almost seedling plants 

 less than a foot high, snch plants being occasionally completely eaten 

 by them, a dozen or more on a plant. They are very rare, apparently 

 accidental on Cist us monspeliensis, but are quite frequent in a species 

 of Helianthemum (barbatum I think, but am not sure of the name) 

 wherever it grows in suitable shaded places in the Esterels. 



After it has cut out its case,the larva lives exactly like a CoJeophora, 

 fastening its case beneath the leaf, and making a hole and a blotch 

 precisely like a Ooleophora, often a nnmber together. In captivity, 

 the moths preferred laying a dozen or so eggs in one leaf, and avoiding 

 others, rather than distributing them singly, a habit that results in 

 the cases so often occurring in families ("familiella"). 



The larva appears to mine in a very small area, so that the case 

 it cuts out is the whole area it has mined up to that date. T make 

 this statement with some reserve, as I am not positive that the larva 

 does not leave one mine and make another during this period, but I 

 think not. It ejects all frass from the mine by a small opening, 

 precisely as it afterwards does from its case. 



When it cuts out the case, it has recently entered the penultimate 

 skin. When removed from the mine, it walks easily, spinning a thread 

 as it goes ; it takes a step with the last segment as with the others, 

 but when not doing so, there being no anal prologs, this segment stands 

 up in the air, as in Platypteryx or Centra. 



The larva is in all respects an Adelid. The peculiar arrange- 

 ment of the terminal segment in substitution of the anal prolegs, is 

 common in that group, as is also the condition of the earlier instars,
