I'KRITTIA. I II 



Head smootli. Foivhoad broad. Ocelli none. Antenna' radwr 

 thick, filiform (viewed through a lens, pubescent), the basal joint short. 

 Tongue very short, barely perceptible. ]Maxillary palpi filiform, con- 

 iiivent. Labial pal]n short, droopini;-, filiform, the third joint distinct, 

 pointed. Wings with long cilia, the anlcrior rather Ijroad, appearing 

 considerably broader from the cilia, the imm- marr/in benrhnj a project- 

 ing tooth of scales, the posterior ovalc-lanceolate. In the anterior wings 

 the discoidal cell is obtuse; there is no secondary cell; the apical vein 

 is forked ; below it are ^we. remote veins ; the snbmcdian is hardly 

 thickened ; the snbdorsal has a long fork. In the posterior wings the 

 costal cell is narrow and elongate, the ajncal vein is simple, below it 

 are two separate veins ; the two last branches of the discoidal cell arc 

 not united in a fork. 



Only a single species is known in this genus, and little is known 

 of its habits ; the larva is entirely unknown.

Head and face dark fuscous. I'alpi grey. Antenn;c I'uscous. An- 

 terior wings dark fuscous, irrorated with wliitish scales, with two indis- 

 tinct pale spots on the inner margin, one a little before the middle, the 

 other at the anal angle ; in the middle of the inner margin is a pro- 

 jecting tooth of dark fuscous scales ; cilia dark fuscous. Posterior 

 wings dark grey, with paler cilia. 



Not common; occurs at Sanderstcad, in ]\lay. I nu-t with it
