 the paratypes will be retained by the writer for ultimate de- 

 posit in the U. S. National Musemn. 



ECTROMATINI. 

 Anagyrus nigricornis n. sp. 



Female: Head shaped nearly as in A. dactylof>ii (Howard"* or A. 

 pseudococci (Girault), being moderately thin fronto-occipitally with the 

 dorsal surface well rounded ; frontovertex nearly twice as long as wide 

 at the posterior ocelli ; the ocelli arranged in an equilateral triangle or 

 nearly so, the posterior pair nearly their own diameter from the eye- 

 margins and about twice as far from the occipital margin; eyes rather 

 large, broadly oval, somewhat diverging anteriorly ; face and cheeks not 

 over one-half as long as the eyes ; the scrobes forming narrow sulci 

 slightly converging above. Antennae inserted close to the clypeal mar- 

 gin; scape broadly expanded beneath with its lower margin nearly uni- 

 formly rounded, about one-half as wide as long; pedicel nearly equal 

 to the first funicle joint; funicle cylindrical, increasing slightly in thick- 

 ness distad with the joints becoming successively shorter, the first three 

 times as long as wide, the sixth a little longer than wide; club oval and 

 nearly as long as the last three funicle joints combined. 



Pronotum arcuate, the posterior margin acutely emarginate medially ; 

 posterior margin of the mesoscutum sinuate on each side of the middle. 

 Abdomen as long as the thorax, the ovipositor not protruded. 



Wings broad, reaching well beyond apex of abdomen; marginal vein 

 fully thrice as long as thick and nearly equal to the slender stigmal, the 

 postmarginal a little longer than the stigmal ; speculum broad and widely 

 separated from the posterior margin of the wing. 



Sculpture finely granular-alutaceous, finer on the mesopleura, slightly 

 coarser on the abdomen, the venter becoming smoother at apex. Eyes 

 with a short, thick, blackish pile; head and thorax covered with a 

 rather thick, appressed, subsquamous pubescence of short, white hair;
