Salfusfq^Jiis Theoh. 



This genus was erected by Theobald (BulL Ent. Res. 6, 1915, 

 p. 138) for an African species possessing 6-segmented antennae (Baker, 

 BulL 826, U.S. Dept. Agr. 1920, states that the genus has 5-segmented 

 antennae, but this is a slip) minutely setulose ; head elongate ; ocular 

 tubercles absent ; fore wing with media twice branched, hind wing with 

 cubitus usually absent ; cauda knoljbed ; anal plate divided, caudal 

 extremity of the abdomen sometimes bilobed ; cornicles cup-shaped 

 or truncate ; body with spines modified into different shapes ; legs 

 modified for leaping. Since the genus was erected several American 

 species have been assigned to it.

 of the head, irregularly chitinised towards the centre. Meso- and metatliorax 

 fused, about equal in length to the head -f- prothorax, slightly chitinised

 chitinised along the segmental margins and occasionally around the bases of

Pupa. — The potashed specimen resembles the apterous $ , except that the 

 body is chitinised only around the bases of the fan-shaped hairs, and in the 

 head being practically all dark.
