This su))family, although distinct, has aflfinities which ally rt with the fiimilies 

 Perilaiiipi(hc and the Eucharkhi', and also with the Ptcromalidir, through the sub- 

 family Sphc<iignderinn'. From the last mentioned it is separated Ijy the ^/'o-spurred 

 hind tibiii', from the others l)y the ceplialic, thoracic and abdominal diilerences 

 brought out in my tables. 



Two tril)es may be recognized : 



TABLE OF TRIBES. 



Me.sonotum with the iiarapsiflal furrows incomplete, indicated only anteriorly ; clypeus transverse, suh- 



lunate, the anterior margin narrowly incised medially Tribe I. Haltieoptcrini. 



Mesonotum with the jiarapsidal furrows complete; clypeus not transverse Tribe II. ■Miseoga.sterini. 



Tribe I. HaUiroptcrhii. 



The incomplete mesonotal furrows are .sufficient to distinguish the tribe. The 

 group is apparentl}' parasitic upon Diptera belonging to the fiimily Anthoniijiidir, 

 and some are recorded from Lepidoptera and Hymenoptera. These latter records, 

 however, are questionable and, additional evidence is needed before the true para- 

 sitism of these insects is definitely settled. 



Many insects are found a.ssociated with the wood-boring (oleoptera, gall-making 

 Diptera, Hymenoptera, Lepidoptera, etc., and it is not easy to tell correctly the host 

 from which you breed several parasites. 



TABLE OF (iENERA. 



1. Females 2 



Males 3 



2. Clypeus trausvei-se, sublunate, the anterior margin narrowly incised medially. 



Marginal vein longer than the stiginal, the latter ending in a small knob ; mandibles strong, 4- 



dentate Halticoptera Spinola (type Diplolrpis flavicomis Spin.). 



Marginal vein usually not longer than the .stigmal, the latter witli a small knob ; mandibles not 



strong, but 4-dcntate, the upper tooth bent, the lower straight Dicylus Walkei- 



(type D. h/naslct, Walk.). 



.3. Palpi abnormal ; marginal vein longer than the stigmal Halticoptera Spinola. 



Paljii normal : marginal vein usually shorter than the stigmal or no longer Dicylus Walker 



? = Tityros Walk. (j'.
