INSECUTOR INSCITI^ MENSTRUUS 141 



Genus FIDIOBIA Ashmead 



The original description of this genus must be amended 

 somewhat ; the f rons is not always smooth ; the antennae are 

 9-jointed in the female, the funicle being 4- jointed ; the meso- 

 notal furrows are visible posteriorly but are shallow wide 

 gashes ; the propodeum has two carinse instead of f oveolse. 



The new species described below is strictly congeneric with 

 the genotype but is larger and its characters more easily dis- 

 cernible. 

 Fidiobia rugosifrons, new species. 



Female.— Ungth, 0.8 mm. Black, antennae, except the 

 brown club, and legs, reddish testaceous ; head and mesonotum 

 with rather coarse almost thimble-like sculpture; scutellum 

 smooth, polished; propodeum with two carina ; apical margin 

 testaceous and carinate. 



• Type locality, Montoursville, Pennsylvania. 

 Type, Cat. No. 20786, U. S. Nat. Mus. 



Described from two females with the additional data, 

 "reared from egg in wheat stubble, P. R. Myers, Coll., emerged 

 April 17, 1916." 



Very similar to flavipes Ashm. but larger, more coarsely and 

 strongly sculptured, the head completely covered with sculpture 

 as is mesonotum except for broad furrows. 

 Micrcdontomerus fumipennis, new species. 



Female.— length, 3 mm., ovipositor about 1.25 mm. Differs 

 from anthonomi by its bluer color, the face more produced 

 below, first joint of funicle subquadrate instead of transverse, 

 antenna darker in color, wing distinctly dusky with a darker 

 area back of stigmal vein ; veins dark brown (instead of honey 

 color) ; hairless line along postmarginal vein less distinct, ex- 

 tending only as far as point of stigmal knob instead of to apex 

 of vein, and with some hairs along anterior side of stigmal 

 vein ; point on stigmal knob longer than width of knob instead 



of shorter. 



Male.— Length about 2 mm. Agreeing with the female ex- 

 cept for secondary sexual characters.
