26 HYMENOPTERA. 



as the greatest wing width, the venation straight, the mar- 

 ginal and submarginal veins unequal in length, the latter 

 longer, the stigmal vein prominent, descending from the 

 caudal angle of the truncate distal end of the marginal vein. 

 Discal ciliation of the fore wings but moderately dense, ar- 

 ranged in regular longitudinal lines. Posterior wings with 

 three longitudinal lines of discal cilia, the caudal one of which 

 is much fainter. Fore wings with a distinct fuscous substig- 

 mal spot and with a long oblique line of discal cilia running 

 back from the stigmal vein. 



Tarsi 3-jointed, with claws, the joints moderately long, the 

 proximal joints longest, the tibial spurs single, those of the 

 cephalic tibiae weakest, the strigils of the cephalic tarsi 

 absent ; tarsal claws weak, hidden by the fleshy pul villus. 

 Mandibles well developed, 3-dentate the two lateral (outer) 

 teeth acute. 



Male. — The same as the female but the abdomen is less 

 pointed, its sides more parallel, its general form stouter ; 

 further, the marginal fringes of the fore wings are longer 

 than in the female. Antennas the same. 



Type. — Trichogramma ceresariim Ashmead. 



A unique genus, doubtless resembling Calleptiles Haliday 

 but at once separated from that genus by the straight vena- 

 tion and the pointed conic-ovate abdomen of the female. 

 The type species is large for the family, very easily seen 

 with the naked eye. The genus is allied with Abbella Gir- 

 ault and differs from it in being larger, more robust ; the 

 funicle joints are longer than wide, the stigmal vein is 

 strongly developed and the habitus is distinct.

 Male. — Length, 1.4 mm. ; large. General color dull honey yellow 

 (pale cadmium yellow), with a tinge of green or even reddish ; eyes 

 delicate rosaceous; ocelli carmine, in a triangle on the cephalic half of 

 the vertex ; the distance between the eyes and the lateral ocelli is twice
