ro. 1812. NEW ICHNEUMON FLIES— VIERECK. 195 



Foerster's classification of the Hemitelini where our species would 

 go on account of the incomplete areolet we find that it attaches 

 itself to Mastrus Foerster. As Mastrus has as yet no species in it 

 we propose to take the liberty to include our species and transfer 

 Mastrus to the Phygadeuoninse near Leptodemas. 



PHYGADEUON (MASTRUS) NEODIPRIONI, new species. 



Female. — Length 6 mm.; exserted portion of sheaths of the ovi- 

 positor about two-thirds the length of the tergum, head black and 

 shining except for the face which while black is dullish and mostly 

 closely punctures, the punctures not clearly circumscribed, basal half 

 of mandibles mostly testaceous, the apical half mostly castaneous 

 margined with black; antennae 27-jointed, from testaceous to brown- 

 ish beneath, fuscous above, palpi mostly stramineous; thorax black

 becoming reddish tinged with black beyond, first tergal segment 

 beyond the spiracles, or the postpetiole, longitudinally striated later- 

 ally; second tergal segment reddish, shining, the apical two-fifths 

 depressed and very smooth, the basal three-fifths not depressed and 

 granularly sculptured; remaining tergal segments smooth and pol-

"Bred from a Diprionid July 18, 1910." M. H. Swenk, No. 1. 



Genus TOXOPHOROIDES Cresson. 

 Type. — Lycor%na% apicalis Cresson. 



Related to Lycorina Holmgren but differs especially as follows: 



Apical joint of antennae as long as or longer than the two preceding 



joints combined; scutel rounded off at apex and narrower at apex 



than long down the middle; propodeum without a basal area and 



with only the arcuate transverse carina x fully developed, no other 



l Tn the male as represented by Glypta mnthoznnata- Ashmead, even this carina is incomplete.
