neric. Cosmorhoe has priority of page, though not of time. The

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 anniilus, 

 which is lighter in the middle, this enclosing the discal spot; 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 gubmarginal cloud- 

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

 beyond discal spot and faint submarginal band ; hind wings w'ith black discal 

 spot, and a fine, quite distinct line beyond marginal space, some darker.

 % , filiform in $ ; thorax untufted. Abdomen .somewhat tufted at 

 end in S ; hind tibiae with all spurs present. Wings broad, even ;

As Mr. Meyrick remarks, in speaking of Cataclysme Hiib., a cor- 

 responding European genus, the venation is very anomalous among 

 the Hydriomenidse, 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 Strophidiinse. The rest of the venation is distinctively of the
