This group is proposed for three genera found only in the American 

 fauna. In the shape of the tibdomen it bears a superficial resemblance : 

 to some of the Acmiittinl^ but the hypopygium is hidden, neither 

 prominent, plowshare shaped nor lanceolate, while from them and the 

 other tribes it is readil}?- separated by the abnormally long- hind coxai, 

 which are four or more times longer thtui thick. 



The characters made use of in the following table may be depended 

 upon to distinguish the genera:

Cheeks armed with a strong tooth behind 2 



Cheeks normal, unarmed. 



Face rugoso-punctate; metathorax completely areolated; areolet in front wings 

 large, jientagonal, the third discoidal cell shorter than the second; trans- 

 verse median nervure in the hind wings broken slightly above the middle; 

 first abdominal segment not espi'cially long, very gradually widened toward 



apex, the sj^iracles placed before the middle (303) Lahcna Cresson. 



Face finely coriaceous; metathorax long, exareolated, but with a transverse carina 

 before the apex; areolet jientagonal, the third discoidal cell much longer 

 than the second; transverse median nervure in hind wings broken below 

 the middle; first abdominal segment very long, the spiracles jilaced a little 



behind the middle (304 ) Xonnns Cresson.
