AUT..-:. ASHMEAD MANUSCRIPT ICHNEUMONIDAE— CUSHMAN. 5 



I have not seen the types of Davis's two species, but doubt very 

 much if they belong to Aperilej^tus ; the shagreened body and highly 

 ornamented head and thorax are foreign to the genus. 



Female.— Langth, ?> mm. ; antennae, 3.5 mm. ; ovipositor, 1 mm. 



Head fully half as thick antero-posteriorly as wide ; temples rather 

 broad ; diameter of lateral ocellus hardly as long as post-ocellar line ; 

 eyes convergent below; clypeus strongly rounded at apex; thorax 

 entirely polished; propodeum entirely without carinae, even the 

 pleural carinae lacking; areolet much longer than wide; abdomen 

 compressed from base of third tergite; ovipositor sheath only about 

 as long as first three tergites. 



Piceous black; pronotum pale, especially the margins; clypeus, 

 mandibles, cheeks immediately at base of mandibles, scape and pedi- 

 cel beneath, tegulae, and legs largely stramineous; palpi and wing 

 bases white; hind tibiae and tarsi somewhat infuscated; wings 

 hyaline, venation brown; abdomen piceous, second tergite in basal 

 middle whitish. 



Type locality. — Franconia, New Hampshire. 



Type.— Cs^t. No. 25008, U.S.N.M. 



One specimen. 



APERILEPTUS DELICATUS, new species. 



" Proedrus delicatus Aslim., n. sp.," Slosson, Ent. News, vol. 8, 1897, p. 237. 



Closely allied to clypeatus Cushman and differing principally as 

 follows : 



Female.— luength, 3 mm.; antennae, 3.5 mm.; ovipositor, 1.5 mm. 



Head distinctly less than half as thick antero-posteriorly as wide, 

 temples sharply receding; diameter of posterior ocellus fully as long 

 as postocellar line; eyes parallel within; clypeus truncate at apex; 

 areolet but little longer than wide ; ovipositor sheath fully as long as 

 abdomen. 



Color as in clypeatus Cushman. 



Type locality.— Ali^'me region of Mount Washington, New Hamp- 

 shire. 



Type.— Cat. No. 25009, U.S.N.M. 



One specimen taken by Mrs. Annie T. Slosson.
