40 HYMENOPTERA. 



margin acute at the distal end of the marginal vein or at the 

 hooklets. Posterior wings bearing three principal lines of 

 discal cilia, the cephalic two lines paired and their cilia closer 

 together in the line, near the cephalic margin, the caudal 

 line with the cilia more distant from each other in the line 

 and that line nearer the caudal margin. Marginal cilia nor- 

 mal, as usual those of the caudal margin distinctly longer 

 than the wing is wide. 



Legs normal but the caudal femora are noticeably stout 

 and the tibiae are longer than the tarsi, the latter slender, the 

 joints moderately long, subequal, the tibial spurs single, 

 straight, absent on the cephalic tibiae. Ventral aspect of 

 tarsi clothed with soft hairs which are moderately long and 

 moderately dense. 



Mandibles with five distinct teeth, the three inner (mesal) 

 ones subequal, longer, the two outer (lateral) ones about a 

 half shorter, subequal, all acute, nearly in a straight line. 



Male. — The same. Abdomen less acute but the genitalia 

 exserted (death) . Antennae with long soft hairs and 4-jointed, 

 the two funicle joints but indistinctly indicated, together with 

 the club forming a long spindle-shaped, knotted or nodular 

 club joint. Composed of scape, pedicel, one ring-joint and 

 a long funicle-club. 



Type. — The following species : 



1. N^eotrichograinnia aciitiveutre species nova.* 



Female. — Length, 1.00 mm. ; variable. Moderately large. General 

 color dark brownish, the abdomen much darker, the posterior femora 

 and terminal tarsal joints dusky, the remaining segment of the legs 

 pallid yellowish as are also the antennae; ocelli ruby red, eyes dark 

 garnet ; venation pallid yellowish to dusky ; wings hyaline but the 

 fore wings fumated proximad out as far as the end of the stigmal vein, 

 the distal margin of the fumated area slightly obliqued caudo-distad 

 involving proximal portions of the discal ciliation. The oblique 

 proximo-caudal line of discal cilia running back from the stigmal vein 

 is curved, containing about nine cilia and slightly caudad of the mid- 

 dle of the wing, joining a nearly reciprocal line running disto-caudad, 

 both forming a broad v-shaped line. The marginal vein bears three 



* As I will show elsewhere, this species is the Trichogramtna japoni- 

 cum of Ashmead. The name is therefore Neotrichogramma japonicuni 

 (Ashmead).
