All of the following species were reared by P. van der Goot, except 

 the first and last : 



Subfamily Encyrtinae. 



LEPTOMASTIX TRILONGIFASCIATUS, new species. 



Female. — Length, 1.60 mm. 



Bright orange yellow, the head and abdomen and legs golden yel- 

 low, the middle coxae and the flagellum black, bullae of the scape 

 dusky. Fore wing with the following pattern : As in auraticorpus in 

 general, but the caudal wing margin is dusky incompletely (only to 

 a point opposite the middle of the marginal vein from about a point 

 opposite the apex of the proximal one-third of the submarginal vein) ; 

 the cephalic margin is dusky very narrowly along the distal half of 

 the venation and more thicldy (with a convex caudal margin) to 

 the apical turn from some little distance distad of the venation ; and 

 there is a distinct oblique stripe midlongitudinally, running to the 

 caudo-distal apex from the middle of the blade opposite .the apex of 

 the stigmal vein; the cephalo-distai marginal stripe is thickest, the 

 mid-longitudinal one next so. Axillae with a rather long carina 

 between them. Scutmn with short, black setae which are scattered; 

 also on axillae and scutellum (four longer setae at apex of the lat- 

 ter). Abdomen a little dusky above. Marginal vein somewhat 

 longer than the postmarginal, wliich is somewhat longer than the 

 stigmal. Otherwise as in auraticorpus. 



The male is the same but with hyaline wings, and the dorsum of the 

 abdomen is black, the meson of propodeum dusky broadly. Vena- 

 tion of male not seen. The scape is shorter and stouter; the pedicel 

 barely longer than wide; the funicle and club with long, scraggly 

 hairs; the club solid with a few clavate sensory organs along one 

 side, longest of the flagellum, funicle 1 next longest, over four and 

 a half times longer than wide ; 6 not much shorter and subequal to the 

 others.
