 tibiae ferruginous, with dusky tips; fourth joint of the tarsi short,

Male. " The smallest of this group, not unlike C. Amman, but the 

 antennas quite different, the forceps light-coloured (and differently 

 formed?), and the wings not white. Pale ferruginous. Vertex, meso- 

 notum, metanotum, and mesosternum pale slaty-grey. Eyes distant, 

 but little notched. Antenna dingy -yellowish, half the length of the 

 thorax ; last joint elongate-elliptical, not one-fourth of the length of 

 the antennas; second and next joints subglobose, then gradually in- 

 creasing in length, and becoming oblong, scantily verticillate, with long 

 hairs, not forming a plume as usual. Wings obscurely hyaline; veins 

 light rust-brown ; pobrachial areolet scarcely passing the fork of the 

 pobrachial vein. Abdomen dusky, with narrow pale incisures ; forceps 

 ferruginous (the claw paler, dilated for half its length, and denticulated 

 internally). Legs pale ferruginous, longer than in C. Ammon ; femora 

 and tibias at the tips (fore pair almost entirely), and tarsi brownish ; 

 fourth joint of the tarsus shorter than the fifth, notched at the tip ; 

 first joint shorter than the tibias." Hal. MSS.
