costal anastomosing with subcostal nearly to end of cell ; 0, 7 short stalked 

 first median at two-thirds, second at five-sixths. 

 Type : Parasthenajiexilinea, sp. nov. 



56. Parastheua flexilinea sp. nov. 



Forewings : hone-colour ; the costal area thickly grey-speckled ; all the lines 

 rnfons grey, darker on the costal edge ; in the basal area are 3 pairs of lines all 

 curved, the last pair rejjresenting the inner edge of the ordinary central fascia, 

 closely followed by the small black cell-spot ; beyond the cell-spot all the lines are 

 bent above vein 6 and below vein 4, being vertical or slightly insinuate between, 

 and oliliipie below vein 4; three with the s[)ace between them faintly darker, and 

 the middle line obscure, represent tiie outer edge of the central fascia, followed by 

 a jiale band traversed by a single line; three submarginal, of which the inner two 

 are thicker than the rest and wavy and denticulate, and the third narrow and close 

 to hindniargin : marginal line dark fuscous, swollen at the ends of the veins, which 

 are themselves brownish at extremity : fringe bone-colour. 



Ilindwingti : the same, but with no basal lines ; the cell-spot and spots at end 

 of veins larger and more conspicuous. 



Underside whitish, with the outer lines distinct ; forewings from base to outer 

 edge of central fascia tinged with rufous grey. Face and jialpi brown ; head, 

 thorax, and abdomen bone-colour : fillet and antennae whitish. 



Expanse of wings : cj, 22-24 mm. : ?, 24-26 mm.

Subfamily TRICHOPTERYGINAE. 



Crypsimetalla uen. nnv. 



Forewiric/s : elongate ; custa straight, becoming convex only at apex, which 

 is depressed and minutely jirodnced ; hindniargin obliipie, with a slight projection 

 at vein 4. 



Jlimlwinfjs : with a very deep excision between veins 4 and 6, and a smaller 

 one before anal angle. 



Forehead jirojecting beneath ; palpi jiorrect, slender, reaching far in front of 

 face ; terminal joint long, acutely pointed ; antennae lamellate, simple ; tongue 

 and frenulum present ; legs long and slender ; the hind-tibiae with four spurs ; 

 scaling fine ; the wings on underside with bands of metallic sj)ots. 



jS'curatioii : forewings, cell quite half as long as wing ; discocellnlar oblicpie 

 below ; first median nervnle just beyond middle, second close before third ; radials 

 from centre of discocellnlar and njjper angle of cell ; 7 missing; X, ',), 1(), 11 

 stalked from well before end of cell : hind wings, costal anastomosing with 

 ubcostal for three-fourths of cell ; 6, 7 stalked ; radial and median nervulcs as 

 in forewings. 



Type : Crypsimetalla aurata sp. nov. 



As the type is nniipie and of very delicate structure, this neuration is given 

 without denudation. Tiie genus stands quite by itself.
