This group was at one time confused with the EuphorincB, but may 

 iie easily separated by the venation of the front wings; all the species 

 I'alling in it having three distinct cubital cells, never less. 



Many of the species also bear a superficial resemblance to some in 

 the next subfamily, or the Mocrocentrlnw, and the greatest attention 

 must be given to the abdominal characters before they can be 

 separated. 



TABLE OF GENERA. 



Hind wings with the marginal cell normal, not widened toward apex and not divided 

 by a transverse nervure 2 



Hind wings with the marginal cell broadened toward apex and divided by a more 

 or less distinct transverse nervure. 

 Hind tarsi usually white (919) Zemlotm Forster. 



2. Front wings with the transverse median nervure either interstitial with the 



basal nervure or jointing the median vein beyond it, the submedian 



cell therefore as long or longer than the median 3 



Front wings with the transverse median nervure joining the median vein before 

 the origin of the basal nervure, the submedian cell therefore shorter 

 than the median (920) Proteins Forster. 



3. First abscissa of the radius much longer than the second; petiole of abdomen 



long and slender, of a uniform thickness throughout 4 



First abscissa of the radius always shorter than the second; petiole of al)domen 

 neither especially long nor slender, widened at apex.

4. Mesonotal furrows distinct; first cubital cell not confluent witli the first discoidal 



cell (922) SapotricJms Holmgren. 



Mesonotal furrows wanting; lir.'^t cul)ital cell confluent with the first discoidal 

 cell (923) Aridelus Marshal 1.

Distinguished from the Euphor'mm by the elongate, se^nle^ not 

 petiolate, abdomen, and from the I/elconinw by the characters made 

 use of in my ta})le of subfamilies. 



Two tribes have been recognized.
