P. georgii u. sp. — Expands 28-31 mm. Palpi quite long, prominent, por- 

 rect, end member drooping, fuscous gray ; clypeus and thorax dark gray. Abdo- 

 men mouse-gray to blackish gray ; fore wings mouse or fuscous gray, with a faint 

 violet tinge ; basal line lighter, distinct, sinuous, edged within with a darkish 

 band ; a middle black line narrow, rounded to behind cell then pointed outwardly 

 on veins, extending in general direction outwardly towards inner margin ; an 

 outer fine black line rounded outwardly to vein 3, then angulated inwardly on 

 veins to inner margin, the lines on veins joining those of median line separating 

 the median space into rounded dots, these sometimes entirely separated, the veins 

 becoming lighter between the parted black line ; the lines have a darker brownish 

 or reddish band within the middle space forming a large rounded discal annulus. 

 which is lighter in the middle, this enclosing the discal sjwt; outer space darker, 

 again enclosing an evenly scalloped, distinct, whitish outer line ; marginal line 

 broken black; hind wings mouse-gray or ocher-gray, with a Eubmarginal cloud- 

 ing forming an indistinct band ; beneath gray fuscous; fore wings with faint line

As Mr. Meyrick rcMuarks, in speaking of Catachjxine lliib., a cor- 

 responding European genus, the venation is very anomalous among 

 the HydriomenidjB, and is, so far as the relations of 6 and 7 with 8 

 and 9 of the fore wings go, the same as the distinctive venation of 

 the Strophidiime. The rest of the venation is distinctively of the
