mesoscutum and in the broadly dilated second antennal joint. 
The middle pair of legs haye a large tibial spur, larger than in 
E. Swederi, and the middle tarsi are larger. Otherwise, except 
the remarkable differences in coloration, it belongs to the same sec- 
tion of the genus, apparently, to which E. Swederi belongs.

Washington, N. H. (F. G. Sanborn.) 
Encyrtus turni n. sp. 
One $. Head and thorax blackish blue with metallic hues. 
Eyes far apart, being twice as much so and much smaller than in 
9 , the distance between them being a little greater than the length 
of one of the eyes. Ocelli placed in a large, broad triangle ; front 
with a sunken rounded pit from which the antennae arise. Mouth 
parts and antennae pale brown, hairy, with rounded joints; sec- 
ond joint very short. Thorax smooth and shining, with minute 
scattered punctures and fine brown hairs, blackish purple, with a 
slight bluish tinge. Wings as usual, clear, not clouded, spur of 
subcostal (as we may call the end beyond the pterostigma) 
enclosing an equilateral triangle, the end of the vein a little 
dilated, but not knob-like. Legs uniformly pale brown. Mid- 
dle legs the largest. Middle tibiae with a single spine large 
and stout, slightly more than half as long as the tarsus. Spine 
and tarsi paler than the rest of the leg, except the terminal joint, 
including the claws which are brown, tip of tibiae also pale. 
Abdomen large, triangular, nearly as long as rest of the body, (in 
the single specimen before us a little convex above); apex not 
very acute, a few long hairs towards the tip. Dark pnrple, but 
with no bluish reflections as in the 9 . 
Length .09 inch. 
9. Eyes large, closely approximating on the vertex, of the 
same distance apart as in E. montinus. Below a deep round hol- 
low for the reception of the antennae, the clypeus rising up in 
the middle, being rather narrow and convex. Labrum and man- 
dibles and other appendages of the mouth pale piceous ; rest of 
head dark purple, while the thorax is bluish purple. Antennae 
dark brown, much longer than in the male, with second joint flat- 
tened and clavate, and the club long, not suddenly dilated, rather 
acute. Thorax dark bluish purple, being more blue than in £,
