Hynienoptera. 163 



.sparsely covered with white pubescence ; cenchri large, 

 white ; calcari about one-fourth of the length of the meta- 

 tarsus ; claws bifid. Second marginal cellule a little longer 

 than the first ; first transverse cubital nervure absent ; 

 transverse basal nervure received beyond the middle of the 

 cellule ; the second recurrent nerv^ure is received about the 

 same distance from the second transverse cubital nervure 

 that the transverse radial is from the second transverse 

 cubital. 



If the first transverse cubital nervure were not absent 

 this species agrees in neuration \\-ith Selandria. With the 

 material at my disposal it is impossible for me to say if the 

 absence of this nervure is normal ; and I therefore leave the 

 species in Selandria. If there are species similar to the 

 species here described, it might be referred to Aneitgrnenics, 

 but that I suspect was found on a Selandria which had the 

 first transverse cubital nervure faint or absent ; and, there- 

 fore, I am inclined to regard Aneiignienus as synonymous 

 with Selandria (cf. Cameron, Mon. Brit. Hym. I. p. 264.)
