Twenty specimens, bred by S. H. Scudder from Pyrameis 
cardui. 
Apanteles limenitidis Riley. 1 
9 . Body stout, dull black as in M. lunatus. Head and body 
covered with a fine silvery idle. Palpi white. Antennae slightly 
stouter than in M. carduicola, the terminal joints being shorter. 
Thorax less polished than usual, finely punctured; propodeum 
coarsely granulated, with an irregular median ridge. Wings hya- 
line; fore wings with the pterostigma dark brown, the veins 
uniformly pale brown, the outer side of the second subcostal 
thickened and darker than the other veins ; second median cell 
broad, subpentagonal, being intermediate in form between that of 
M. pieridis and M. lunatus in shape, but with the outer side dis- 
tinctly bent below the middle. Trochanters black. Fore femora 
honey yellow; middle pair shaded above except at tip with blackish, 
hind pair black. Fore and middle tarsi honey yellow (with no red- 
dish tinge), last joint of middle tarsi dusky ; hind tibiae dark just 
beyond the outer half ; hind tarsi dark brown. Abdomen granu- 
lated on two basal segments and on base of third, beyond brightly 
polished and giving off a deep steel blue reflexion ; edge of basal 
segment testaceous, not connected with any visible testaceous spot 
beneath.

Bred from Limenitis Disippus by C. V. Riley. 
Cocoon cylindrical oval, length .16 inch. 
Microgaster lunatus n. sp. 
One 9. Body dull black, not shining as in some other species, 
stout and thick as in A. limenitidis. Head and antennae covered 
with an unusually dense silvery pile, the antennae rather thicker 
than in M. pieridis ; palpi jiale testaceous ; front rather broad 
between the eyes ; thorax dull black, propodeum as usual granu- 
late ; with no median ridge as in A. limenitidis. Wings clear ; 
fore-wings with pterostigma broadly triangular as usual, blackish 
1 Since this paper was presented for publication Mr. C. V. Riley’s Notes on North 
American Microgasters (Trans. Acad. Sc. St. Louis, published April 6, 1881), has 
appeared, in which he adopts the subdivisions Apanteles and Microplitis of the old 
genus Microgaster. It is possible that my species M. pieridis, M. atalantae, M. cardui- 
cola and M. lunatus belong to Apanteles, but as the types are not now in my hands, I 
cannot surely tell. July 1, 1881.
