marginal vein distad indetemiinately a little beyond the venation, the 

 latter dusky. Legs dusky except articulations, tips of tibiae (more 

 broadly in the cephalic ones) and the tarsi. Club two and a third 

 times longer than wide at base, temiinating in a pair of the rather long 

 setce. Marginal cilia of the fore wing short but not extremely so, dis- 

 tinct, the fore Aving shaped about as in Trichogramma. Mandibles 

 equally tridentate. Body as in Pterygogramma. Middle tibial spur 

 slender, sHghtly less than half the tarsal length, the caudal one rather 

 stout. Male the same, the abdomen more blunt at apex. 



Described one male, five females on a slide labelled "53-42. 

 Reared from egg-mass of Membracis tectigera. Port of Spain, 

 British West Indies, March, 1915, F. W. Urich. " 



Types: Catalogue No. 19932, U. S. N. M., the above speci- 

 mens on a slide. A second- slide with fragments retained as 

 paratypes. 



Oligosita oophagus new species. 



Female: Length, 0.70 mm. 



Bright golden yellow, the eyes darker, last tarsal joint black, the 

 metapleurem with a longer than wide, oblique black spot. Differs 

 from americana in that the funicle joint is distinctly longer than wide, 

 the fore wings broader and with more discal ciliation, the pedicel more 

 slender and so on. From comosipennis in that the fore wings are not so 

 broad, the color much lighter, the pedicel a little more slender.- The 

 male differs in bearing a broad black band across' the abdomen just 

 distad of the middle. Distal edge of fore wing embrowned. 



Described from six males, twelve females reared from an 

 egg-mass of a leaf-hopper embedded in a leaf of sugar cane, 

 Diego Martin, British West Indies, January, 1914 (F. W. Urich). 



Types: Catalogue No. 19933, U. S. N. M., two males, four 

 females on a slide. Six females on another slide, the same 

 number, as paratypes. 



Oligosita comosipennis in Girault, 1914 (Canadian Entomolo- 

 gist, p. 328) is no doubt this new species. 



Achrysocharis partifuscipennis new species. 



Female: Length, 0.55 mm.

 yellowish, the postmarginal vein shorter than the stigmal. Mandibles 

 tridentate. Caudal wings with about five lines of discal cilia where 

 broadest. Head and thorax uniformly scaly, the propodeum smoother, 

 with no median nor lateral carinse. Parapsidal furrows complete.
