ART. 4. NEW PARASITIC HYMEN OPTERA GAHAN. 21 



as long as the three succeeding funicle joints combined; scape slightly 

 thickened and equal in length to the pedicel and funicle combined; 

 thorax about as long as broad; abdomen much broader than the 

 thorax, nearly circular in outline as viewed from above. 



Head and prothorax dark reddish yellow; the vertex more or 

 less infuscated; mesoscutum anteriorly usually more or less ob- 

 scurely stained with reddish; remainder of thorax and abdomen 

 entirely black ; legs brownish mixed with yellowish without any very 

 definite color pattern, the femora, apices of tibiae and the tarsi 

 usually more or less yellowish ; antennae dark brown. 



Male. — Length 0.95 mm. Wings fully developed. Head trans- 

 verse, weakly reticulated; occiput concave and margined at vertex; 

 antennae 12-jointed, scape slightly expanded beneath; pedicel a 

 little longer than the first funicle joint, which is distinctly longer 

 than broad, narrower at base than at apex and the longest of the 

 funicle joints; joints 4 to 10 of the antennae moniliform; joints 11 

 and 12 slightly longer and thicker and more closely joined together, 

 forming a 2-jointed club; mesoscutum faintly reticulated and 

 sparsely hairy; scutellum prominent, convex, broader than long, 

 rounded behind and nearly smooth; propodeum rugulose, very short 

 medially, sharply and perpendicularly truncate behind; abdomen 

 shorter than the thorax and about as broad as the thorax, narrowed 

 at base and broadest behind the middle; the first tergite longitudi- 

 nally striate basally, smooth at apex; second tergite also striate at 

 base, the apical two-thirds of second and all of the following tergites 

 smooth; wings with rather coarse discal cilia; stigmal vein longer 

 than the marginal ; postmarginal subobsolete ; basal vein present and 

 distinct. Antennae and legs, except coxae, testaceous; head faintly 

 piceus; thorax and abdomen black; wings hyaline. 



Type-locality. — Middle Bass Island, Ohio. 



Type.—C2it. No. 26183, U.S.N.M. 



Described from twenty-one females and three males reared by 

 Miss Mary Auten, July 4, 1921, from an unknown spider's nest 

 taken under bark of a tree. Five female and one male paratypes 

 in the collection of Ohio State University at Columbus, Ohio. Type, 

 allotype, and sixteen paratypes in the United States National Mu- 

 seum. Antenna of type female on a slide. 



Subfamily Telenominae. 



f HANURUS PROMACHIVOKUS, new species. 



Very similar to Phanurus tahanivorus Ashmead but differs by hav- 

 ing the first funicle joint twice as long as broad and only a little 

 shorter than the pedicel, the elevation on the dorsum of first abdomi- 

 nal segment distinctly more prominent, and the forewings somewhat
