This group is the only one in the subfamily Ophionmrn having but 

 a single apical spur to the middle tibiae, all the others being armed 

 with two spurs. It also contains a genus with only one recurrent 

 nervure — as in the family Braconidm — namely, Pharsalia Cresson. 



This curious genus is extremely rare and is, without doubt, identi- 

 cal with OpMonellus Westwood described from Mexico, and placed in 

 the famil}^ Evaniidce. 



Only three genera fall into this tribe as follows. 



TABLE OF GENERA. 



Second recurrent nervure present, distinct 2 



Second recurrent nervure wanting. 



Metathorax long, sloping off posteriorly and produced into a slight neck beyond 

 the insertion of hind coxse, coarsely rugose, exareolated, but with a median 



longitudinal sulcus (653) Pharsalia Cresson^= OpMonellus Westwood. 



2. Metanotum exareolated; antennfe slender, filiform; second recurrent nervure 

 received before the transverse cubital nervure. 



(654) Nototrachys Marsha.]\= Trachynoius Gravenhorst. 

 Metanotum aieolated at base; antennae somewhat thickened; second recurrent 

 nervure received hthind the transverse cubital nervure. 



(655) Eugnomus Forster. 



Tribe IV. ANOMALINI.

 1887. AnomaUnaTuoMsois, Opus. Ent., XI, p. 1048. 



1894. Anomalonini, Tribe I, Ashmead, Proc. Ent. Soc. Wash., Ill, p. 277. 

 1900. AnomaUni, Tribe IV, Ashmead, Smith's Insects of New Jersey, p. 580. 



This tribe, as well as those which are to follow, has two apical spurs 

 on the middle tibiie and two recurrent nervures in the front wings. 

 The second recurrent nervure joins the cubitus hehhid the first trans- 

 verse cu1)itus, or it is at the most interstitial, but never joins the cubi- 

 tus before the first transverse cubitus. 



These characters readily separate this and the following tribes from 

 the Ilellwigiini^ the Ophioninl, and the NototracMni. 



The AnomaUni are, however, separated from all the other tribes, 

 except the Campoplegini^ b}^ the metathorax being produced at apex 

 into a distinct neck that extends beyond the insertion of the hind 

 coxae. From the Canipojylegini they are separated by the much longer 

 and more strongly compressed abdomen, b}^ the petiole being only 

 slightly and gradually thickened posteriorly, never abrupth^ swollen, 

 and })y the hind tarsi being most frequentl}-, although not always, 

 distinctly incrassated or much thickened, especially in the males.
