or nearly ; hroioni also has segment 4 longest but much shorter than in 

 poloni and wholly polished-direct dorsal aspect, hanksi has a paired 

 median channel on the propodcum and segment 5 of the abdomen is 

 longest. 



Black except the Imlla of scape, knees, tips of tibiae and the tarsi, 

 the latter whitish. Umbilicately punctate. Venation pale, the 

 stigmal vein slightly shorter than the marginal, the latter subequa{ 

 to the postmarginal. Abdominal petiole very short, the abdomen 

 usual in shape. Body as in BruchopJiagus funehris. Abdomen 

 glabrous dorsad except the proximal third of segment 4 and all of 

 the small segment 5. A button-like tubercle at base of abdomen on 

 each side of the petiole. Pedicel globuhir; funicle 1 a half longer 

 than wide, the others moniliform; club 2-jointed, 1 a little wider 

 than long. Types compared. 



The male is similar except for sexual characters. Its antennae 

 are similar in segmentation but the funicle joints are exercised and 

 with whorls of long hairs, the club about equally divided. 



Described from numerous pairs reared from the larvae of an Agro- 

 myza in bean roots. Los Banos, Luzon, Philippines (C. F, Baker). 

 February, 1916. 



Types.— Csit. No. 20S65, U.S.N.M. Two males, five females on 

 tags, male and female antennae, female caudal legs and fore wings 

 on a slide. 



The species is respectfully dedicated to Marco Polo. 



EURYTOMA ILLINOISENSIS. new species. 



Female. — Differs from maculipes in having the scape black except 

 at base, the caudal tibiae are less broadly reddish at apex, the post- 

 marginal vein is subequal to the stigmal, scgmxcnt 5 of the abdomen 

 somewhat shorter, funicle 1 is somewhat longer, while the propodeum 

 on each side of the meson is coarsely rugulose, has no distinct basin 

 and the median chaimel is deep, simple, not distinctly bifoveate at 

 base. From stigmi Ashmead in that the median channel of the pro- 

 podeum does not enlarge at base and .is but feebl}^ bifoveate there, 

 and the stigmal and postmarginal veins are shorter, the venation 

 paler. Closely allied with stigmi Ashmead. Funicle 1 over twice 

 longer than wide at apex; club 2-jointed, 2 is long as funicle 1. 



Described from two females, Urbana, Illinois. Reared in connec- 

 tion with Isosoma. (R. D. Glascow). 



Types.~Cs,i. No. 20629, U.S.N.M. Two females on tags, caudal 

 tibiae and an antenna on a slide. 



Also, females reared from Elymus, Taber, South Dakota (C. N. 

 Ainslie) ; in one of these the middle tibia was black dorsad only.
