3. Froiis not broad, uearly smooth, opaque or minutely shagreeued, or witli only a few iiiinulo imiictures ; 

 stigmal and postmargiual veins unequal, the latter only slightly devi'loptd. tlie uiar^iiial vein very 



short, uearly puuctiform ; frout wings hyaline but with a discoidal cloud Prionomastix Blayi- 



(type Eacyiim morio Dalman). 



TinisE III. Mlrini. 

 In this tribe fall the vast majority of the genera of the subfamily Eucyrthue, dis- 

 tinguished from the others by the mandibles, which are somewhat differently 

 shaped, and tridentate at apex. The tribe was fully discussed in the Proceedings of 

 the U. S. National Museum for 1900. The table of the genera published below is 

 practically the same as published in that work, except that some slight changes 

 have been made to enable me to incorporate some interesting new genera unknown 

 at that time. 



TABLE OF GENERA. 



1 . Females 2 



Males. 58 



2. Mandibles rather long, with acute teeth, the apical tooth usually the longest, rarely with the two 



apical teeth longer than the itiner ; labrum conspicuous ; front very closely punctate, or finely coria- 

 ceous, the thimble like punctures absent, or the punctures smaller or more sparsely scattered ; wiugs 

 not oruat'^, and usually with a very short, or a punctiform, marginal vein, the hind wings usually with 

 a long costal cell that extends to the booklets ; abdomen usually more or less compressed towards 

 apex, the ventral valve extending to the anus but not plowshare-shaped ; head as viewed from in 

 front usually somewhat longer than wide, often much longer than wide, or subtriangular, the scrobes 



forming a triangle 8 



Mandibles shorter, with the teeth smaller, less acute and equal or nearly ; labrum not conspicuous ; 

 frons frequently but not always with a series of large, thimble-like jjunctures ; wiugs variable, fre- 

 quently ornate or dusky, although often hyaline ; scrobes usually semicircular 13 



3. Marginal vein punctiform, not or scarcely longer than thick (very rarely twice as long as thick), the 



postmargiual vein not at all or only slightly developed, very rarely as long as the stigmal vein ; stig- 

 mal vein is rathe- long, always more than twice the length of the marginal, or much longer; body 



metallic or lustrous 4 



' Marginal vein not puuctiform, at least twice as long as thick, but usually much longer, the postmar- 

 giual vein longer than the stigmal vein 12 



4. Head viewed from in front long, subtriangular, much longer than wide, the cheeks, or malar space, 



long 5 



Head viewed from iu front nut or scarcely longer than wide, the cheeks, or malar space, not especially 

 long ■. 11 



5. Front Wmgs with a marginal fringe G 



Front wings without a marginal fringe. 



Antenna; very long and slender, the flagellar joints all very long, cylindical, the sixth being at 



least four times as long as thick, the preceding still longer Psilophrys Mayr 



(type Encyrtiis loni/iconiis Walk.). 



6. Pedicel fully three times or more longer than thick at apex 7
