if a lichen had grown upon it. These black dots may have been — 
the frass of the larva, which showed through the epidermis. 
Where the ichneumon had escaped from these dotted blotches, 
it had cut out an oval or rounded hole in the upper surface of the 
blotch. Once, before I broke open one of these mines from which 
the ichneumon had escaped, I found the pupa-skin in situ, with its 
broken end just touching the hole, through which it could be seen. 
The hole was about 0'2 millimeter in diameter. 
I found several of these blotches which had no hole in them, 
and yet I found no ichneumon within, but the larva-skin flat and 
empty. This led me to think that the fungus which I have men- 
tioned may kill and exhaust some larve. 
According to Ratzeburg (Ichneumonen der Forstinsecten, i, 
(1844), p. 158), this ichneumon belongs to the genus Eulophus, a 
the family of Chalcidide. I have not been able to make a satis- 
factory figure of it, owing to the injured condition of the only three 
examples which I succeeded in preserving. It may be call 
Eulophus cemiostomatis, if it has not been previously described. 
he imago is metallic green or coppery; the wings are trar 
parent, somewhat iridescent ; the fore wings crossed by a brownish 
cloud beyond the middle. The fore wings have no other Mage 
than a double one near the front margin, which is bent at about 
one-quarter, and ends in a fork at about three-quarters of the 
distance between the base and the tip, sending one prong of 
fork in line with the vein, and the other towards the inner angle 
of the wing. The inner margin of the fore wing is also thi wi 
for a short distance near the middle; and the front margin of ve 
hind wing is thickened along more than half its length a 
base. All the wings are fringed around their margins, ani ij
