204 EXOTIC NEUROPTERA. 



Pictet's type of Gjdpopteryx cancellata has the vein from 

 anal cell forked, two costal cross-veins, one near base, and 

 one at tip ; hind wings with three cubital cross-veins near 

 tip ; radial sector of fore wings with one branch, the median 

 vein before the large basal cross-vein is rather weak but dis- 

 tinct, in both wings the cubitus forks at this cross-vein ; last 

 joint of tarsi plainly longer than basal two together; the 

 setae with many very short joints. 



Paragripopteryx differs only in having a cross-vein beyond 

 end of the subcosta. 



The Pteronarcini includes only the two northern genera, 

 Pteronarcys and Pteronarcella occurring in northern North 

 America and Siberia. 



The subfamily Nemourinae can be divided into two tribes 

 as follows : 



Anal cell with one simple vein ; setae usually distinct Capnini. 



Including Capnia, Capnura, Capnopsis, Arsapnia and Capio- 

 neura. 



Anal cell with a forked vein ; setae rudimentary Nemourini. 



Including Nemoura, Perlomyia, Udanioceria , Leuctra, Taeniop- 

 teryx (with three subgenera) and Taenio7tema . 



Ochthopetina Clarissa n. sp.— Almost wholly clear pale yellow ; 

 tips of palpal joints dark ; antennae beyond base brownish ; ocelli 

 and eyes black ; tarsi rather dark ; last five joints of anal setae dark ; 

 venation wholly pale yellowish, probably greenish when alive. Ocelli 

 nearly contiguous ; lateral bosses smaller than ocelli, nearly round, 

 and hardly more than their diameter from the lower inner edge of 

 eyes. Pronotum broader in front than behind, slightly convex on 

 front margin, sides with several prominent rugae; wings rather long, 

 about ten costal cross-veins, several beyond end of the subcosta ; 

 radial sector forked about the width of a cell beyond the anastomosis, 

 four median cross-veins, four cubital cross-veins, and four branches 

 of cubitus beyond. Female ventral plate evenly convex at tip. Length 

 12 mm. 



Type. — 9 . From Los Banos, Philippines (Baker). 



Eustlienia costalis n. sp.— Black; a yellowish white fringe on 

 base of clypeus and labrum ; setae with yellowish hair. Wings beauti- 

 fully violaceous, only indistinctly marked with pale around veins; a 

 pale band beyond middle, the costal area reddish-yellow, but not as 

 in E. spectabilis. The venation is as in E. spectabilis, but the wings 

 are rather shorter than in that species ; the recurved superior append-
