and distinctly notched above at the sutures; the first funicle joint is 

 two or more times as long as the pedicel. 



7ype: Agromyzaphagus detrimentosns, new species. 



In Ashmead's Classification of the "Chalcid Flies" this 

 genus apparently falls nearest to Coccidenc\rtns, but differs 

 from that genus in that the antennal club is less than half the 

 length of the funicle. The fact that the eyes are bare distin- 

 guishes it from Ageniaspis and the short pedicel will serve to 

 separate it from most of the other genera. 



Agromyzaphagus detrimentosus, new species. 



Female. Length 1.5 mm. Antenna? black with very short whitish 

 pile, scape slightly metallic; scrobes deeply impressed; eyes reddish 

 brown; face and cheeks bluish-green tinged with brassy, the former 

 finely shagreened, the latter delicately lineolated. Head above and 

 mesocutum finely shagreened, brassy green; scutellum copper-colored 

 its sculpture finer than that of the mesoscutum; mesopleurse steel- 

 blue, very finely lineolate; metathorax and abdomen smooth, shining, 

 impunctate, nearly black, but often slightly metallic. Wings hyaline, 

 the anterior and posterior margins without cilia, the apical margin 

 with very short cilia; veins brownish. Coxae all metallic green; tro- 

 chanters testaceous; anterior femorse dark brown, their apices and 

 tibiaa and tarsi pale yellow; median femorse and tibiae dark brown, the 

 apex of femoras, base and apex of tibia?, and their tarsi pale yellow; 

 posterior femorae and tibiaa black, more or less metallic, their tarsi 

 yellowish. 



Male. Exactly like the female, except in the antennal characters, 

 as pointed out in the description of the genus and the fact that the 

 flagellum is wholly testaceous instead of black. 



Type: No. 14355, U. S. National Museum. 



Habitat; College Park, Maryland. 



Described from eleven females and seven males reared July 

 19, 1911, by Mr. O. G. Babcock and the writer, from the pu- 

 paria of an agromyzid fly belonging to the genus Leucopis. 

 The flies, which are probably Leucopis uigricornis, were feed- 

 ing in the larval state upon an aphis infesting apple and also 

 one infesting a species of thistle.

SCELIONIN^. 

 Hoplogryon kansasensis, new species. 



Female. Length 2.5mm. Black, more or less shining. Antennae 

 strongly clavate; scape long and reaching about to the forward ocel-
