nigrolatera ; tliis may be a sexual character, however, as 

 only males of typical nigrolatera and females of the new 

 variety have been made known. In the present form the 

 pubescence of the legs is very short, appicriseii, and not at all 

 cons-picuous. The wings are much paler, greyish sub- 

 hyaline ; vein Sc considerably shorter, ending far before the 

 fork of /?2+3 ; '^Cg is clost-r to the tip of Sc^, Sci alone being 

 only about two-tliirds i?2+3 j J'l typical nigrvlattra Sci is 

 longer than i?2+3 j anal veins a little more divergent at the 

 wing-margin. The valves of the ovipositor are short and 

 flesliy its in the group.

 petiole of cell M-^ more tlian three times the basal deflection 

 of Cui or about two-fifths of vein Cmj beyond it ; basal 

 deflection of Cui })erpendicular, nearly twice as long as the
