Neuroptera from Western China. 435 



beiicatli (including cox£e and underside of trochanters) citron- 

 jellow ; an isolated metallic blue or green streak on the meta- 

 thor.ncic pleural. Legs (excepting at base) black. Abdomen 

 above bronzy green or purplish, segments 8 to 10 snow- 

 white, ])ruinose ; beneath black or with bluish j)ulverule3- 

 cence, underside of first segment yellow. Superior appendages 

 ab<nit the length of the tentii segment, black, forcipate, 

 thickened at the base, the apical half suddenly turned inward 

 almost at a right angle, dilated and upturned at the tip; on 

 the outer edge of the inturned portion are four to six dcnticu- 

 lations. Inferior a])pcndages black, only slightly shorter than 

 the superior, subparallel, distant, flattened, their apices inter- 

 nally much dilated in a triangular manner, the upper edge 

 oblique and finely denticulated, the lower angle perhaps 

 forming a tooth (but from the manner in which the opposing 

 apices are applied one to the other it is difficult to decide). 



Wings hyaline, faintly tinged with olivaceous. Neuration 

 black ; pterostigma oblong, 2 millim. long, covering two and 

 a half to three cellules, black ; 14 to 17 antenodal nervules 

 in the anterior wing (many of the postnodal nervules are not 

 coincident in the costal and subcostal areas) ; two nervules in 

 the quadrilateral. 



Length of abdomen 39 millim. ; length of posterior wing 

 31 millim. 



Two adult males. 



N.B. — Notholestes, M'Lach. (Ent. Month. Mag. vol. xxiv. 

 p. 31), 1SS7 ,= Caltpha'a, Hag. (Selys, Add. Synop. Galop. 

 p. 5), 1859, and N. Elioesi, Al'Lach. [l. c. p. 32),= C. con- 

 fusa, Hag. (1. c). I have compared the typical examples of 

 each ; that of C. confusa is less mature. The pterostigma 

 appears slightly broader and shorter in the type of G. confasa^ 

 but in all probability only in the way of individual variation 

 (its paler colour is a result of imnu\turity). 



C. consimilis is very similar, and the same description 

 would apply almost equally well to either (the types of con- 

 similis are still more mature), except that the inferior append- 

 ages appear to be formed in a different manner, and that there 

 are two nervules in the quadrilateral instead of one. 



In describing Notholestes as new I overlooked Caliphoea^ on 

 account of the latter having been placed in the " Ldgion 

 Calopteryx,^^ with which I venture to think it has no relation- 

 ship ; and 1 adhere to my original opinion that its affinities 

 are with Dicterias. In the description of Caliphcea the words 

 " Ailes petiolees jusqu'au niveau de I'arculus " are incorrect 

 [cf my description of Notholestes).
