32 NEUROPTERA. 



I have not compared the types ; however the dimensions 

 given by Pictet in his description do not agree with the 

 measurements in his figure. On examining the Stephensian 

 types I noted that the four species above cited were identical, 

 but I have no specimen before me which has been compared 

 with the types. There is nothing in the descriptions which 

 militates against their being referred here, but a further in- 

 vestigation is necessary in order to render my opinion certain. 

 In order, therefore, to avoid mistakes, I have placed none of 

 the Stephensian names foremost. A Prussian specimen 

 which, after comparison with the Stephensian types, I had 

 labelled B. jiJiceopa, Stephens, is the sub-imago of C. Rho- 

 dani. Stephens himself refers this species to B. lateralis 

 (Tllust. Qb, 8). The description, however, appears to refer 

 to a sub-imago, but I cannot say with certainty of what 

 species. 



3. C. DiMiDiATUM, Curtis, Phil. Mag. 121, 6; Steph. 

 69, 7, $ imago ; C, cognatum, Stephens, 69, 6, $ 

 imago ; C. virgo, Stephens, 70, 7 (partim) $ imago. 

 Imago. Head and thorax shining chestnut-brown ; 

 abdomen clay-coloured, the tip brownish ; the tips 

 of the segments annulated with brown ; caudal fila- 

 ments pale yellow, the joints annulated with brown ; 

 anal forceps thin, cylindrical, pale brownish ; penis 

 small (apparently cylindrical and double) ; legs pale 

 yellow, the anterior legs brownish; wings hyaline; 

 venation yellowish ; apical portion of the marginal 

 field with some oblique veins ; and closer to the mar- 

 ginal veins are some irregular tmnsverse veins, which 

 form smaller double cells. In the specimens which I 

 take for the female of this, the abdomen is throughout 

 of paler colouring ; the wings and venation are as in
