92 LEPIDOPTERA. 



HoMCEosoMA SAXicoLA, H. Vaughan. 



This species is veiy closely allied to H. 7iimbella, with 

 continental specimens of which I have had an opportunity 

 of comparing it, and doubtless stands in many of our collec- 

 tions under that name. It is, however, a rather longer, 

 narrower-winged insect than nimhella. Its costal white dash 

 is much more conspicuous, and the two longitudinal white 

 lines, which are plainly seen in saxicola, are but feebly ex- 

 pressed in nimhella. The dots at the inner third of the wing 

 are placed obliquely in nimhella, whereas, so far as my ob- 

 servation goes, in saxicola they are generally placed one 

 over the other, or, if there is any obliquity at all, it is in the 

 direction opposite to those of nimhella. Then the female of 

 saxicola is narrower-winged, and the costa is a trifle straighter. 

 The true nimhella appears to be intermediate between saxi- 

 cola and the reductella of Mann. 



For this addition also we are indebted to Mr. Vaughan, 

 who, in 1867, reared specimens from larvae found feeding in 

 the flower-heads of a species of chamomile in the Isle of 

 Man in September, 1866. 



From what he recollects, Mr. Vaughan believes the larva 

 was obese and greenish, with darker blotches in the back. 



Peronea proteana, Herrich-Schaffer. 



This is a species which there seem to be fair grounds for 

 considering distinct from potentillana, Cooke, seeing that 

 the former has been bred in abundance from larvae found 

 feeding on Comarum palustre by the Hon. Thomas de Grey, 

 while the latter, according to Mr. B. Cooke, feeds exclu- 

 sively on Fragaria. Whether it be distinct from Coma- 

 rianttf Zeller, is another matter which has not yet been
