 in fore wings the gradates, and marginal forks black, and part of the 

 costals, radials, and branches of radial sector dark at one or both 

 ends, origin of radial sector black; in hind wings the gradates are 

 not dark, the marginal forks partly dark, and the marginal vein 

 black on outer portion; stigma in hind wings distinct, hardly so in 

 the fore wings; both wings broad; seven or eight gradates in each 

 series in each wing, the series nearly parallel, and the inner series 

 rather nearer the radial sector than to the outer series; third cubital 

 cell very long (in L. azevedoi very short) ; about 25 costal cross-veins

Chrysopa nimbosa, sp. nov.

 Bangui. E. Le Moult. Two specimens. 



Close to C. conradtina Navas; the wings spotted as in that species, 

 also the head and antennae so marked. In the wings the stigma is 

 not so distinct, only black-bordered veins, and in the hind wings the 

 stigmal band is more interrupted. In both wings the discal veins and 

 those near middle of hind border are margined with pale yellowish 

 brown ; and in several cells so margined behind the stigma the central 

 area is silvery white; the thorax has a broad black band across be- 

 tween the bases of both pairs of wings. Venation as in C. conradtina. 

 The abdomen has the last two dorsal segments black, and a median 

 black stripe on dorsum to middle of length.

 is a red line to the pronotum, latter with a red stripe each side but 

 remote from the side margin; anterior lobe of mesonotum with red
