[lead obtuse, relracted, with apjiri'sscd scales. OroUi none. Au- 

 teniia) icifh ihkkhj-ncl joints, in the J pubescent-eiliahul, belbro the 

 apex .slightly serrated. Tongue of moderate length, clothed with scales. 

 Pal])! rather s/tort, ascending, rather compressed, aciuniiiate. Wings 

 elongate ; the anterior beneath with a brush at the base ; the posterior 

 acuminate. Tu the anterior wings only /o«/' veins proceed from the 

 discoidal cell below the apical vein ; iu the posterior wings a single 

 vein proceeds from the transverse vein. 



The two last species I have placed in this u'eiuis, exhiliit several 

 discre])ancies : in torqv.ateHa the anterior wings arc oUuu;/ ; the 

 apex of the posterior wings is obltise ; th(^ tongue is vaked ; the 

 shorter palpi are not ascending, witli the apex almost obtnse. 

 Iiicoiiijrurtla 1ms the antennLie rather thick, Jirc veins from the 

 discoidal cell of the anterior wings to the hinder margin, and (ico 

 veins from the transverse vein of the posterior wings. 



The remaining species form an extremely natnral genns, of 

 wliich the most remarkable peculiarity is the position in which 

 the perfect insects sil when at rest; the wings being almost folded 

 round the short thick body, meeling behind it nearly in a |)oinl, 

 uhich the thick blunt head of the insect renders more prominent; 

 they frecpient grassy ])laces and are rather active, tlying close to 

 the ground; tlie females of most of the species have a piile spot 

 on the underside of the abdomen. Of none, excepting (7ie,/ojju- 

 dlelhi, is the larva known ; of tJiat s[)ecies the larva feeds in a 

 web between united leaves of C/icnnjtuirniiii and Atriple.r, where 

 it s])ins a while oval cocoon jjrcvious to its transformation; it 

 only frequents those plants wliieh gn)w in sheltered situations. 



Tliere seems to be a great variety of closely allied species on 

 the continent, but only seven of the tyi)ical form of the genns 

 liavc occurred in this country; they may be arranged as I'ol- 

 k)ws : — 



a. Anterior wings unicolorous. Species 1, 2, -t. 

 a a. Anterior wings with scattered whitish scales, not forming distinct 



spots. Species 3, 5. 

 a a a. Anterior wings with distinct white or whitish s[)ots. Sp. (i, 7.
