426 Mr. E. M'Lachlan on 



clothed with rather long whitish hairs, and there are similar 

 hairs, but denser, on the abdomen. Legs whitish, clothed 

 with concolorous hairs ; tarsi slightly yellowish ; claws testa- 

 ceous, much dilated at the base, the apical portion slender, 

 much curved, extending beyond the dilated portion. 



Wings broad, subacute ; in the anterior pair the costal 

 area is narrow at the base, but the costal margin soon becomes 

 gradually rounded and the area correspondingly broad ; the 

 margins with a dense fringe of whitish (or yellowish-white) 

 hairs, and there are long divaricating hairs on the neuration ; 

 this latter is wholly pale green, with the following exceptions 

 — in the anterior wings the veins in the costal area at the 

 base are dusky blackish at their upper ends, and two or three 

 small veins at the end of the postcostal region are incrassate 

 and dusky blackish (but not always so) ; in the posterior 

 wings the costal veinlets are blackish towards the base (in 

 some examples there is an appearance as of long dusky spaces 

 on the subcosta, but not of a decided nature) ; in both pairs 

 of wings the sector does not run quite parallel with the radius, 

 and the two series of gradate nervules are also not parallel ; 

 in the anterior wings there are ten to twelve nervules in the 

 inner and ten to fifteen in the outer series ; thirty to thirty-five 

 costal nervules before the pterostigmatic area (this latter very 

 faintly yellowish) ; dividing nervule of the third cubital 

 cellule extending to rather more than half its length (but 

 varying) and about one third beyond the insertion of the 

 superposed nervule. 



Expanse 36-46 millim. 



I have seventeen examples before me. 



In general form, pale colour, and very hairy margins and 

 neuration this species bears some analogy to the much smaller 

 European Ch. alba, L. ; but I think there is no real affinity, on 

 account of the differing arransfement of the neuration. It also 

 recalls species of the genus Leucoclirj/sa, M'Lach.* ; but m 

 til at genuSj as defined by me, the labrum is excised, the 

 antennae are much longer than the wings, and the divided 

 portion of the third cubital cellule is more or less triangular 

 (not oval). 



N.B. — Dr. Gerstiicker, in describing some new species of 

 Chrysopidai from Japan (Mitth. nat. Vcr. Xeu-Vorpommern 

 mid Kiigcn, 1893), has a ^^Xo(IiocJn-i/sa" rohu st a, vchich he 

 compares with "iV\" polh'da, Schn., and "X" bij>uuctatay 

 Burm. But these two species have nothing whatever to do
