exclude such species as did not precisely answer to 

 M. Guenee's somewhat vague definition, *' Palpes en hec 

 aigu, ne cU passant ixis la tete de plus d' line longueur '' ; but 

 the antennal structure, as rendered by him, is too elastic 

 to enable any lepidopterist to decide what is a Coremia : 

 it runs, " Antennes pubescentes, ciliees ou pectinees chez 

 les (? ." I therefore would restrict the group to species 

 with the antenna} " ciliated," by which term I understand 

 M. Guenee to designate delicate pectination ; if pubes- 

 cence be admitted there is no reason for excluding such 

 as have simple or filiform antennae. 



109. Coremia deeipiens, n. s. 



? . Much like C. infundihdata of Guenee, from 

 Brazil, Colombia, and Venezuela* ; greyish fuliginous, 

 rather pale ; the undulated lines across the primaries 

 blackish, but not well defined ; an undulated white line 

 limiting the external border, which is darker than the 

 ground colour, a blackish apical patch ; central belt 

 tolerably wide, slightly narrowing towards the inner 

 margin, and a little angulated at the median vein ; darker 

 than the ground colour, commencing upon the costal 

 border in two unequal blackish spots, the inner one well- 

 defined and triangular, the outer continuous with the 

 external boundary line of the central belt, which is 

 black and undulated ; a third blackish spot within the 

 cell just above the median vein and between its first two 

 branches ; a marginal series of black spots in pairs, fol- 

 lowed by a slender pale buff line at the base of the 

 fringe ; fringe of secondaries also with a pale basal line ; 

 under surface greyish brown ; wings sericeous, with 

 darker irrorations ; fringes with a pale basal line ; 

 secondaries with a dark brown disco-cellular spot ; an 

 undulated ill-defined discal line, spotted upon the veins 

 with black. Expanse of wings, 28 mm. 



" Pines valley, in December." — T. E. 



It is possible, when we know the male of this species, 

 that it may prove not to be a Coremia, but its resemblance 

 to C. infundibulata seems to justify its being placed 

 provisionally in that genus. 



* A species in which the male antennaB are distinctly ciliated ; it 

 has been redescribed by Walker as Melani2)pei')rocluctata, Cidaria 

 remissata and C instipata, showing how little M. Guenee's defini- 

 tion assisted him in determiuin" its generic location.
