Notes on North American Mymaridae and 

 Trichogrammatidae (Hym.). 



By A. A. GIRAULT, Washington, D. C. 



1. Abbella subflava Girault. The following specimens: "Para- 

 sites of chinch bug eggs, J. W. McCulloch, Manhattan, Kansas." 

 Also, "Reared from jassid eggs, C. N. Ainslie, Elk Point, South 

 Dakota, July 25, 1914. Webster No. 11874." 



2. Abbella auriscutellum new species. 



Female. Length, 0.60 mm. Black, the scutellum and postscutellum 

 bright golden yellow, also the caudal margin of the scutum narrowly 

 (and apparently the median line of the scutum more or less, very 

 faintly). Coxae and femora black. Scutum scaly reticulate. Rest of 

 legs very pale yellow, including the knees broadly. Antennae dusky 

 yellow, the two fuiiicle joints subequal. 



Fore wings with the distinct substigmal spot continued right across 

 the wing, the stripe broader and fainter than the spot and often broad- 

 ly interrupted caudad of the middle; the wing also infuscated across 

 under all of the submarginal vein and part of the base of the mar- 

 ginal. Discal ciliation of the fore wing dense, normal, about twenty 

 lines where widest, the marginal cilia rather short (about one-sixth 

 the greatest wing width). No line of cilia back from the stigmal vein. 

 Caudal marginal cilia of hind wings distinctly longer than the longest 

 cilia of the fore wing, about twice longer than the average width of 

 the blade. Caudal wings with two complete lines of discal cilia cepha- 

 lad and one caudad, the latter spaced farther apart in the line. 



Abdomen about as in Trichogramma japonicum Ashmead. Abdo- 

 men disto-dorsad suffused with yellowish. Mandibles tridentate, the 

 two outer teeth more distinct than the inner. 



Described from six females "reared from eggs of Drae- 

 culacephcda mollifies, Tempe, Arizona, May 26, 1914, E. H. 

 Gibson, Coll. Webster No. 12, 211." 



Type: Catalogue No. 19182, United States National Mu- 

 seum, Washington, D. C., a female on a slide with two 

 paratype females and two heads of paratypes. 



3. Oligosita americana Ashmead. Several specimens of both 

 sexes reared from jassid eggs, Las Vegas, New Mexico, C. N. 

 Ainslie, Webster No. 6089. 



4. Oligosita sanguinea claripes new variety. 



Female. Like the typical form but the legs are white excepting the 

 red caudal femora (not all pale brownish as 1 in the other form) and
