No 2315. TRIBESOFICHNEVMONINAE—CVSHMAN ANDROHWER. 393 



Tribe LISSONOTINI. 



As here defined this tribe includes most of the genera placed 

 there by Ashmead and other writers. Of the Nearctic and Pale- 

 arctic genera Eyho'phanes Foei-ster and Phytodietus Gravenhorst are 

 excluded. HyhopJianes, we agree with Thomson, is a Tryphonine 

 belonging in the sub tribe Thymaridina, tribe Mesoleptini; Phyto- 

 dietus forms the new tribe Phytodietini; while Phidias, unknown to 

 us except from descriptions and Vollenhoven's figure, will very 

 likely not run here, and probably should be referred to another 

 subfamily. 



The group is very homogeneous, and v/hen once understood is 

 easily recognized. It is very closely allied, especially through 

 Arenetra Holmgren, to the Banchini as represented by Exetastes 

 Gravenhoi"st and its nearest allies. The males of some of the Lisso- 

 notine genera are likely to be confused with males of the Tryphonines 

 and apparently certain portions of that very heterogeneous sub- 

 family are rather closely related to the present tribe. Within the 

 subfamily as here treated its closest relative is the Glyptini, the 

 abdominal structure being the only real difference, and these two 

 tribes form a group not at all closely related to the rest of the 



subfamily. 



GLYPTINI, new tribe. 



The tribe Glyptini is founded for the genus Glypta Gravenhorst 

 and its allies, Teleutaea Foerster, Dihlastomorpha Foerster, and 

 Gonoblasta Foerster. Ctenochira Foerster, and Hoplitophrys Foerster 

 are unknown to us, but apparently belong here. All of these genera 

 have heretofore been referred to the tribe Ichneumonini. 



The remarks above concerning the affinities of the Lissonotini 

 apply in large part to the Glyptini. 



LYCORINI, new tiibe. 



As here defined this tribe includes of described genera only Lycorina 

 Holmgren and Toxophoroides Cresson. These genera have hereto- 

 fore been placed in the tribe Ichneimionim, to which they are perhaps 

 more closely allied than to the Glyptini, with which the structure of 

 the tergites superficially allies them. The real affinities of the tribe 

 are very obscure. 



PHYTODIETINI, new tribe. 



The only genus known to us that is referrable here is Phytodietus 

 Gravenhorst, heretofore placed in the Lissonotini. Although super- 

 ficially resembling the Lissonotini it is doubtful if it is closely allied 

 to that tribe. It may be that it has some affinity with the Ly- 

 cormi, and the ovipositor suggests the possibility that they may 

 have had a common origin with the Ciyptinae.
