 tibioQ distally shaded to pale yellowish-white, nil tarsi yellow. 

 Basal halfoV third antennal joint li.^ht yellowish-brown and 

 distal half (the constricted part) of both 3 and 4 lighter than 

 the basal half. Wings grey-brown. 



Head 0"8 as long as broad across eyes, and nearly as long 

 as the prolhorax ; checks gently diveroing to base. Antennae 

 2'7 times as long as the head ; relative lengtiis of joints 3-8 

 approximately: — 38 : 56 : 30 : 40 : 7 : 13. Joint 4 curiously 

 constricted and produced in tiie form of a stem distally. 



Fore-wing witii a series of 10 spines in upper vein,

 mencing just beyond the first bristle in the long series of 

 upper vein. 



Abdomen elongate, ninth segment with a pair of dorsal 

 bristles in additiun to the postero-marginal series. 



This species comes near to sjosledti (Tryb.), imtatus, Bagn., 

 and variabilis, Bagn., but is readily separated from these and 

 all other described species of the genus by the long fourtii
