Antennae in 9 14-jointed, the third joint sliorter than the fourth, in $ 

 r5-jointed; second abdominal segment not occupying much more than 

 half the length of the whole surface of abdomen Antistrophus Walsh 



(Type A. pisum Walsh.) 



Antennae in 9 13-jointed, the third joint much shorter than the fourth, in 



$ 14-jointed, the fourth joint much longer than the third; second 



abdominal segment occupying fully two thirds the whole surface of the 



abdomen dorsally, but ventrally it is much shorter Asclepiadiphila 



Ashmead (Type A. stephanotidis Ashm.) 



13. Antennae in 9 14-jointed, the third joint very long, nearly twice as long as 

 the second ; second abdominal segment large, occupying about four fifths 

 the whole surface of the abdomen .... Timaspis Mayr 



(Type T. phaenixopodos Mayr.) 



Tribe V. — Eschatocerini. 



The members of this tribe attack plants belonging to the order Legumindseae. 

 Not many species are known and these fall into a single genus, Eschatocerus Mayr, 

 described from South America. I have, however, an undescribed species from 

 California and I suspect when our sensitive plants, milk-vetches and our many other 

 leguminous plants are carefully examined for galls, many other genera and species 

 will be discovered. 



The tribe is easily separated from the others by the antennae being inserted 



high up on the face above an imaginary line drawn from the apex of the eyes, and 



by peculiarities of venation. The single genus may be characterized as follows : — 



Front wings with a callosity at the union of the basal nervure with the median 



vein and another along the first abscissa of the radius, the areolet being 



obliterated and the cubitus originating from this callosity ; hypopygium 



plow-share shaped, without a prominent spine; antennae in 9 13-jointed, 



the third joint about equal to the fourth, in $ 14-jointed, the third joint a 



little longer than the fourth Eschatocerus Mayr 



(Type E. acaciae Mayr.) 



Subfamily III. — Ibaliinae. 



This group is quite distinct from all others in the venation of the front wings, 

 in having the abdomen long and very strongly compressed, cultriform or knife 

 shaped, and in the totally different shape of the legs, the hind tibiae being very 

 long, longitudinally furrowed, with two apical spurs, while the basal joint of the
