most they can only be considered a geographical race of 

 nigra, and females from Mingrelia are large, but other- 

 wise not appreciably distinct. 



All the European males seen by me have the wings 

 reduced to mere scales^ but the c? from Turkestan has 

 effective wings. 



On the discovery of a second British Gaj^nia, the 

 Chloroperla bifrons of Newman required investigation. 

 Mr. Waterhouse has very kindly compared the single ? 

 type in Stephens' collection with both species, and is of 

 opinion that on the whole it agrees most closely with 

 C. nigra, although the basal end of the lower intercubital 

 cellule is hardly in the condition more typical of this 

 species. As already indicated this cellule is usually 

 distinctly biangulate and rather broad at the basal end 

 in C nigra.

Generic characters : Hindwings smaller than forewings and 

 without any folded portion. Sub-costa terminating about the 

 middle of the wing. No transverse veinlets between costa and 

 radius, beyond the junction of the sub-costa. Maxillary palpi 

 apparently with the two basal joints short, the others long ; 4th 

 and 5th sub-equal, the 3rd slightly longer. Antennae sub-setaceous, 

 joints elongate, only 3 or 4 at the base shorter, Tarsi with minute 

 middle joint, 1st and 3rd joints long, sub-equal. Seta3 very short, 

 with 9 or 10 joints only (probably only 7 in the $ if the difference 

 be not due to mutilation). 



Description : blackish, shining, clothed with short yellowish 

 pubescence. Antennte blackish fuscous, nearly black, clothed 

 with short yellowish hairs, with five or six stronger erect hairs at 

 apex of each joint. Pronotum about same breadth as head, trans- 

 verse, margins all slightly rounded, a distinct border all round, 

 disc rugose. Wings greyish sub-hyaline, neuration fuscous. Legs 

 fuscous with yellow pubescence. Setae fuscous. In the only ^ 

 examined the last ventral segment is somewhat rounded at the 

 apex, and from either side of it arises a flattened piece ; these
