1856. Miscogasteroidse, Family XIV (partim),^ Forster, Hym. Stud., IL, pp. 19, 24 



and 59. 

 1875. Pteromalina, Tribus (partim), Thomson, Hym. Skand., IV., pp. 12 and 216. 

 1885. Pteromalinae, Subfamily (partim), Howard, Ent. Amer., I., p. 198; II. , 1886, 



p. 33. 



1885. Mischogastrides, Subtribus Thomson, Hym. Skand., IV., pp. 16 and 219. 



1886. Mischogastrides, Tribe, Howard, Ent. Amer., II. , p. 33. 



This subfamily, although distinct, has affinities which ally it with the families 

 Perilampidce and the Eucharidse, and also with the Pteromalidse, through the sub- 

 family Sphegigasterinfe. From the last mentioned it is separated by the f«'o-spurred 

 hind tibi?e, from the others by the cephalic, thoracic and abdominal differences 

 brought out in m_y tahles. 



Two tribes may l)e recognized : 



TABLE OF TRIBES. 

 Mesonotum with the parapsidal furrows incomplete, indicated only anteriorly ; clypeus transverse, sub- 

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



Mesonotum with the parapsidal furrows complete; clypeus not transverse Tribe II. Miscogasterini. 



Tribe I. Halticopterhii. 



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

 group is apparently parasitic upon Diptera belonging to the family Antliomyiidse, 

 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 associated with the wood-boring Coleoptera, gall-making 

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

 from which you breed several parasites. 



TABLE OF GENERA. 



1. Females , 2 



Males 3 



2. Clypeus transverse, sublunate, the anterior margin narrowly incised medially. 



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

 dentate Halticoptera Spinola (type Diplolepis flavicornis Spin.). 



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



strong, but 4-dentate, the upper tooth bent, the lower straight Dicylus Walker 



(tyjje D. hjnastes Walk.). 



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



Palpi normal ; mai-ginal vein usually shorter than the stigmal or no longer Dicylus Walker 



? = Tityros Walk. c?.
