42 Psyche [April 



longer than wide. Scape long and slender, the pedicel not half its 

 length. 



Described from one female on a slide labelled "Webster No. 

 11824, Elkpoint, S. D., March 28, 1914. Reared from a coccid 

 on Muehlenhergia, C. N. Ainslie." The four ring- joints in the 

 genotype are verified. Type: Catalogue No. 19210, U. S. N. M., 

 the foregoing female. 



Aneristus oculatipennis sp. no v. 



Female: Length, 1.65 mm. Black, the tarsi white; apex of 

 scutellum very narrowly around the margin and a broad band 

 across the scutum just back of the cephalic margin, yellowish 

 white; band on scutum occupying somewhat over a third of the 

 surface. Propodeum centrally at apex suffused with yellowish. 

 Body very finely scaly, the head and thorax with numerous, small 

 setigerous punctures, densest on the scutum. Cephalic femora 

 strongly compressed. Fore wings hyaline but with a large, three- 

 fourths-complete circular smoky ring from somewhat less than 

 the distal two thirds of the marginal vein and extending beyond the 

 venation, its open fourth facing the caudal wing margin and partly 

 closed by a fainter dusky stripe opposite the opening and along 

 the caudal margin; the distal margin of the ring is less than its 

 width (not diameter) from the blade's apex; this ring makes a 

 central, large ocula some distance distad of middle, opposite distal 

 marginal vein. Stigmal vein sessile, minute, globular. Middle 

 tibial spur long and stout as in normal encyrtids. Axillae ad- 

 vanced. Parapsidal furrows mere sutures. Caudal femora and 

 tibia compressed, the tibiae with stiff black bristles dorsad and 

 with two stout, black, subequal spurs. Mandibles broadly sub- 

 truncate but bidentate as in Baoanusia, the first tooth shorter than 

 the large truncate second one. Scape pale beneath; flagellum 

 subcylindrical, the funicle joints a little flattened, 1 nearly as long 

 as the scape, three-fourths longer than wide at apex, 3 a little 

 longer than wide, much larger than the pedicel; club 1 slightly 

 wider than long. One distinct ring-joint. Maxillary palpus 

 2-jointed, the second joint ending in a long slender bristle; labials 

 1-jointed and similarly terminated. Club well-defined. 



From five females reared from Saissetia oleoe, Catacaos, Peru. 

 The date of the rearing is September 14, 1912. Rust, collector.
