CREMASTUS. 499 



Range. AVorlcl-wide. 



Cameron was of opinion that his genus belonged to the Campo- 

 >PLEGJDES, wherein he wished to place it near Zaporus, but it is 

 distinct from that tribe in its very short and nearly right-angled 

 -radial cell in the front wings, and tlie basally wanting median 

 nervure in the hind wings ; the latter feature is shai-ed with the 

 PoEizoNiDES, which differ in having a much shorter submarginal 

 nervure and the basal superiorly incrassate at tlie pterostigma. 

 Cameron's diagnosis of Faurolexis will be found to coincide very 

 well witli that of Cremasius, Grav., as given by Thomson (Opusc. 

 Ent. xiv, p. 1441).
