lum; abdomen a little longer than the head and thorax united, wider 

 than the thorax, less than twice as long as wide, elliptical posterior 

 to the petiole ; second tergite as wide as long, widest at the apex where 

 it is twice as wide as at base; following segments united half as long 

 as the second, each one finely punctate, broadly transverse; sixth ter- 

 gite as long as the two preceding united, broadly rounded apically. 

 Dark reddish brown; legs and antennae (except flagellum) bright 

 yellow; flagellum and petiole yellowish- brown; tegulae rufous pos- 

 teriorly.

Fidiobia Ashmead, Journ. Cincinnati Soc. Nat. Hist., 1895, p. 171. (Monobasic.) 



Genotype. — Fidiobia flavipes Ashmead. 

 Rosneta Brues, Bull. Wis. Nat. Hist. Soc, vol. 6, 1908, p. 157. (Monobasic.) 



Genotype. — Rosneta tritici Brues. 



Head transverse, wider than high seen from in front; vertex 

 rounded; lateral ocelli nearer to the eye margin than to the front 

 ocellus; antennae in the female jnine-jointed, short, with a three- 

 jointed club, funicle four-jointed, filiform; antennae in the male nine- 

 jointed, with a distinct three-jointed club; third joint as long and as 

 thick as the second, longer than wide; fourth broadly transverse, very 

 thin; fifth and sixth short, rounded, longer than the fourth; thorax flat- 

 tened ; pronotum seen from above appearing as a transverse curved line, 

 thicker just in front of the tegulae; mesonotum transverse, sepa- 

 rated from the scutellum by a fine suture; notauli indicated by broad 

 gashes in the posterior half of the mesoscutum; scutellum broadly 

 transverse, margined laterally ; propodeum shorter than the scutellum, 

 with lateral ridges and with two dorsal longitudinal carinae; wings 

 veinless, pubescent, not distinctly ciliate at their margins; abdomen 

 flattened, with no strong growth of pubescence on it; first tergite 

 transverse, with two lateral foveae at its base separated by a median 

 elevation; second tergite longer than wide, with two lateral basal 

 foveae and a shallow depression between the elevations separating 

 them. 



Two valid species are known in this genus. Both are found in the 

 Eastern States. E. flavipes is recorded as being parasitic in the eggs 

 of Fidia viticida on grape vine. It is strange that the species is so 

 often found in sweeping wheat stubble but that the specimens so 

 procured are really flavipes , I entertain no doubt for I have compared 

 a number of them with the types. Rosneta tritici Brues is identical 

 with. flavipes . The difference in the length of the abdomen is not of 

 any significance since the apical segment.: are telescopic.
