both black at tip ; hind tarsi brown, growing darker towards the 
tips ; yellowish at base of basal joint. Abdomen of the same 
length as thorax, rugose on the two basal segments, polished 
beyond. Basal segment twice as long as second, the basal one 
being distinctly carinate, a yellowish line on each side of these two 
segments seen from above and extending downwards, forming a- 
large spot. Ovipositor a little longer than the abdomen is wide, 
the outer blades black and clavate, inner or true ovipositor honey 
yellow. 
Length £, .14; 9, .15 inch, exclusive of the ovipositor. 
Bred from Pyrameis Atalanta by S. H. Scudder. 
Micro g aster pieridis n. sp. 
Five £, two 9. Black, head and thorax a little more hairy 
than usual, the hairs being long and white. Ocelli prominent. 
Palpi pale testaceous ; antennae black. Thorax finely punctured 
as usual. Tegulae black. Propodeum coarsely punctured as 
usual, but with no median ridge. Wings as usual, pterostigma 
broad, triangular, brown, veins pale brown; the venation differs 
from that of M. atalantae to which it is nearest allied, by the 
outer side of the first subcostal cell being rounded rather than angu- 
lated, while the bend, though much curved is rather below the 
middle than above, as in M. atalantae. The cell itself is thus ren' 
dered much less polygonal in form than usual. Legs, anterior and 
middle pair honey yellow, claws dusky, hind femora honey yellow, 
blackish at tips, tibiae honey yellow on basal two-thirds, beyond 
pale brown, tarsi pale brown, claws darker. Abdomen black, 
coarsely punctured on the two basal segments with a median ridge 
in the second segment, forming a yellow line on each side above, 
extending to the third segment. Sides of these two segments 
honey yellow. Ovipositor short, concealed as usual. 
Length £ .10—12; 9 .12 inch. 
It is closely allied to M. atalantae, being of the same size, but 
differs in the curved outer side of the first subcostal cell, making 
the cell itself less polygonal ; in the honey yellow spots at each 
side of the base of the abdomen ; and in the hind femora being 
tipped with black, while the distal one-third of the tibiae and all 
the tarsi are pale brown. The ocelli are also more prominent. 
Bred from Pieris rapae by S. H. Scudder.
