and tibiae more or less dusky) and a little over basal fourth of the 

 abdomen, except the lateral margins. Fore wings hyaline but bearing 

 a conspicuous, moderately larger, round fuscous spot in the middle 

 of its blade, suspended from the apex of the stigmal vein. Pedicel 

 and fanicle 1 elongate, the former about thrice longer than wide at 

 apex, clavate, a little longer than funicle 1 which is thrice longer than 

 wide; 2 elliptical oval, a half longer than wide, wider than 1 ; 3 oval, 

 a little shorter than 2. Club ovate, about as long as the pedicel 

 excluding the distinct terminal spines which is as long as its third 

 joint. Propodeum rugulose yet with a distinct median carina, the 

 spiracle moderately small round, its own diameter from the cephalic 

 margin. Mandibles tridentate. No noticeable punctures on thorax 

 but scattered minute ones occur.

Type.— Cat. No. 20857, U.S.N.M., the female on a tag, the head 

 and a fore wing on a slide. 



TETRASTICHUS FASCIATUS Ashmead, 



The color is golden yellow with five narrow cross-stripes on the 

 abdomen; the few punctures along lateral margin of scutum very 

 minute, setigerous. Propodeum with no lateral carina, ver}^ short, 

 more so at the meson, the spiracle oval. Scutellum with two, long 

 black setae along the lateral side of the first or mesal groove distad of 

 middle. Funicle 1 twice longer than wide, 3 somewhat shorter, sub- 

 equal to the pedicel. Short ''stylus" of abdomen black. Forewings 

 broad. A well-marked species, the club bearing a spicule at apex. 

 There are three ring-joints, the third short. 



Seven females compared with the types and reared in the type lo- 

 cality from Cecidomyia manihot (F. Watts).

Genotype. 



Antennae inserted somewhat below the middle of the face but above 

 the ventral ends of the eyes, 9-jointed with two ring-joints, the club 

 2-jointed, funicle 1 elongate. Mandibles stout, 5-dentate, the inner 

 three teeth feeble. Caudal tibial spurs double, stout. Club with a 

 minute terminal nipple, about equally divided. Marginal vein dis- 

 tinctly shorter than the broken submarginal, over twice the length of 

 the large stigmal, the postmarginal longer than the stigmal. Form as 

 in Secodella but ciliation of the forewing normal. Parapsidal furrows 

 deep, complete. Scutellum simple, rectangular. Propodeum with a 

 strong, acute median carina only, the spiracle elliptical, large, cepha- 

 lad. Body strongly scaly. Original description otherwise correct 

 but the tibiae and scape are reddish and the forewing bears a fuscous 

 spot, oblique and small, from the base of the marginal vein and besides 

 are lightly stained centrally, especially cephalad.
