cylindrical and hardly at all increasing in width distad, clothed with 

 an abundant and rather long pubescence, which is suberect and 

 equally thick throughout, the club solid and pubescent at its base like 

 the funicle. 



Type of genus. Aenasioidea latiscapus Girault. 



Aenasioidea has no close affinity with Aenasius Walker, with which 

 it was compared by Girault, but on the other hand has descended 

 evidently from an ancestral type common to both itself and Aphycus. 

 The four known species, three from North America and one from 

 Japan, were all reared from species of Kermes.
