surface; the hypopygium short, bluntly cultriform; the ovipositor as 
long as the thorax and abdomen united. The hind spurs short, the 
longer not one quarter of the length of the metatarsus. 
The head is large, cubital, with the temples well developed, longer 
than the top of the eyes ; the occiput is not transverse. Ocelli in a wide 
triangle, the hinder separated from each other by a slightly greater dis¬ 
tance than they are from the eyes, which are separated from the man¬ 
dibles by one-third of their length. There are 2 keels down the middle 
of metanotum. 
This genus has not quite the appearance of the Microgasterinoe, the 
head being too cubital, through the well-developed temples. Charac¬ 
teristic are the closed radial cellule and the well-developed parapsidal 
furrows; the antenna), too, are shorter and stouter—more moniliform— 
than they are in, e.g ., A'panteles. 
Ectadiophatnus tachardioe , sp. nov. 
Black, smooth, shining, the legs rufo-testaceous, the hind femora in 
the middle and the hind tibiae and tarsi infuscated ; palpi white; the 
costa, parastigma and stigma fuscous, sparse, the nervures white. Pub¬ 
escence short, sparse, white on the head and thorax, the abdomen bare, 
as long as the thorax; its 1st segment is longer than it is wide at the 
apex ; its sides depressed ; the 2nd is almost as long as it. ? . 
Length 2 mm., ovipositor 1*75 mm. 
Bred from Lac, December 14. 
The antennae are not much longer than the head and thorax united 
and are covered by a microscopic pile; the scape is twice longer than 
wide and is as long as the 1st joint of the flagellum. The sheaths of 
the ovipositor are thin and are not thickened towards the apex. 
Microgasterinae. 
Apanteles tacliardice , sp. nov. 
Black, the palpi and spurs white, the apex of the anterior femora, 
tbe anterior tibiae and tarsi, the middle tibiae to shortly beyond the 
middle, their tarsi and the hinder tibiae and tarsi testaceous, the hinder 
darker in tint than the others; metanotum opaque, strongly aciculated, 
a longish oval shining depression in the centre, the sides margined by
