NO. 1942. N^W SPECIES OF ICHNEUMON-FLIES— VIERECK. 579 



HABROBRACONIDEA BICOLORIPES, new species. 



Type-locality. — Rainbow, Connecticut. 



Type.— Cat. No. 15009, U.S.N.M. 



Female. — Length 5 mm.; black and shining; first joint of flagel a 

 little longer than the second, superior and posterior orbits, the latter 

 above, more or less brownish; mesosternum brownish; wings infus- 

 cated, second abscissa of radius as long as or a little shorter than the 

 first transverse cubitus and a little longer than the second transverse 

 cubitus; hind coxse, trochanters and femora reddish; propodeum 

 with a median longitudinal brownish line; median longitudinal 

 embossed area on the second dorsal abdominal segment extending 

 a little beyond the middle, apex of second dorsal segment subemar- 

 ginate, the false suture between the second and third segments, 

 crenulate; abdomen reddish throughout and mostly polished, the 

 second dorsal segment with a faint carina on the middle of each side; 

 hypopygiurh sharply pointed and surpassing the pygidium; exserted 

 portion of ovipositor nearly as long as the body. 



Labeled, "No. 325, June 25, 1910, S. N. Spring." A paratopotype 

 measures 3.5 mm. in length. The paratypes indicate that the sculpture 

 of the second doreal abdominal segment is subject to variation and 

 that the basal embossed area on the third dorsal segment may be 

 poorly developed or virtually wanting. 



MACROCENTRUS AMICROPLOIDES, new species. 



Type-locality. — Bethany Center, Genesee County, New York. 



Type.— C&t No. 15010, U.S.N.M. 



Female. — Length 4 mm.; apparently related to M. marginator 

 (Nees), from which it differs chiefly in the Amicroplus-like distal 

 trochanters, the armature of which is atypical or apparently wanting, 

 in the brownish face, in the anterior edge of the clypeus being arched 

 rather than subemarginate, in the stramineous scape and pedicel, in 

 the stramineous prothorax, in the rest of the thorax being brownish, 

 in the almost colorless membrane of the wings, in the almost entirely 

 stramineous legs, in the rather irregularly reticulate propodeum and 

 in the sculpture of the third dorsal segment occupying most of the 

 basal three-fourths of the segment. 



Labeled, "June 26, 1911." Reared in association with Archips 

 argyrospila by R. W. Braucher under his No. 136. 



Allotype. — Essentially as in the type except in the much paler 

 thorax. 



Labeled, "C. U. Exp. No. 882, Sub. 3, June 18, 1911."
