NE^Y BRITISH SPECIES. 45 



I may add, that Professor Zeller entirely concurs with 

 Mr. Barrett in considering staintoyiiana a good new species. 



Sericoris double dayana, Barrett (Ent. Mo. Mag., 

 vol. viii., p. 126). 



S. douhledayana is allied to cespita7ia, but, as ably 

 pointed out by Mr. Barrett, differs from it in the first place 

 by the form of its wrings, which are short and truncate, 

 those of cespitana being narrow, with straighter costa, and 

 slightly produced tip ; again, the female douhledayana is 

 fully as large as the male, whilst in cespitana, and others of 

 the genns, the female is considerably the smaller of the 

 sexes ; then, the markings are much more sharply defined in 

 douhledayana., and the pale fascia before the middle is 

 narrower and more regularly formed. 



Mr. Barrett, who has abundant opportunities of observing 

 the habits and habitats of both species in nature, has never 

 found a single cespitana in the fenny haunts of douhle- 

 dayana; nor has he ever seen douhledayana on the 

 "Buck" Sand at Brandon, where dark forms of cespitana 

 abound; nor on the celebrated Hill of Howth, where he has 

 met with all sorts of queer varieties of cespitana ; in fact, 

 he is perfectly confident that the two insects are totally dis- 

 tinct from one another. 



DiCRORAMPHA HERBOSANA, Barrett (Eut. Mo. Mag., 



vol. ix., p. 27). 

 In a masterly paper on that most perplexing group the 

 Dicroramph(E, in which he begins by demolishing my poor 

 Havidorsana, Mr. Barrett, to whom all Microlepidopterists 

 ought to feel deeply grateful for the pains he has taken to 

 set our Tortrices in order, introduces to our lists the above-
