is certainly none of the plants mentioned above, and I am not aware 

 that it has ever been bred, but I conjecture it to be attached to 

 Centaurea. 



Dr. Kennel describes and figures ndana under its own name, and 

 I judge both description and figures to refer to tlie true species; 

 but he then proceeds to suggest that as all the examples of udana 

 which have come before him have been females and all those of 

 manniana {^^ nohdana) males, it is not improbable that both are 

 sexes of a single species, and adds that this suggestion is accepted by 

 Lord Walsingham ("was audi Walsingham annimmt"). This is a 

 still more astonishing conclusion ; there is no question that it is a 

 false one. My examples of ndana were taken by myself amongst 

 Alisma in the brick-pits at Cambridge, and include both males and 

 females, the sexes being quite similar in form and colou/mg ; in the ^ 

 antennae the ciliations are about 1, much as in notulana, the joints 

 somewhat more sub-cordate in form, whilst in notulana they are sub- 

 quadrate, but the difference is sliglit. The species is immediately 

 distinguished from notulana. and manniana by the more elongate wings 

 and different olive-brown colouring. The food-plant is Alinma, the 

 other half-dozen plants cited by Dr. Kennel being certainly erroneous. 

 I possess females as well as males of nottdana and manniana also, and 

 in each case the females are quite similar to the males. 



I have recorded as identical with manniana a species which I 



have received freely from India and Ceylon (the only PhaJonia yet 



made known from the Indian region), though I must admit much 



uneasiness in accepting the view that an insect of specialised habits 



could occur both on the Wiltshire Downs and at the mouth of the 



Ganges. In connection with the above enquiry, however, I was led 



to make a more critical examination of this species, and I now find 



it to be distinct from mamiiana audits allies, and therefore describe it 



as new. 



Phalonia mellita, n. sp. 



(J 9 . 9-14 mm. Head, palpi, and thorax pale ochreous or whitish-ochreons. 

 Antennal ciliations of ^ 1. Abdomen light grey. Fore-wings elongate, posteriorly 

 somewhat dilated, costa gently arched, apex obtuse, termen slightly rounded, 

 rather oblique ; pale ochreous, glossy or silvery-iridescent ; markings deep 

 yellow-ochreous or golden-ochreous, sometimes tinged with fuscous on costa and 

 dorsum ; sometimes a few minute dark fuscous strigulae on costa and dorsum ; 

 a more or less extended suffusion along costa from base ; an oblique spot or 

 streak from dorsum near base, sometimes nearly obsolete ; a moderate or rather 

 narrow median fascia, obtusely angulated above middle, tending to be obscurely 

 interrupted there; usually a more or less developed streak of dark fuscous suf-
