The series l)efore us fully agrees with the description of this 
species, to which it invariably runs in working over Brunner’s 
key, except for two discrepancies. The subgenital plate of the 
male is described as triangularly eniarginate, while in one 
male the margiii is truncate, in another arcuate-emarginate, 
while the third has the margin abnormally compressed and not 
comparable. Other material of the species, now before us, does 
show this margin varying to subtriangularh' eniarginate. The 
margins of the ovipositor are described as '‘non crenulatis, ” 
which is true to the extent that they are more distinctly serrulate. 
The species has not been recorded since the original description. 
Its produced, strongly incurved cerci of the male are quite dis- 
tinctive as far as our acquaintance with the gejiiis goes.

Anaulacomera rusa new species (Plate III, figs. 8 and 9.) 
Apparently allied to A. harpago Brunner, but differing in the 
femora having a few spines on their ventro-cephalic margins, in 
the cerci of the male being simply bifurcate distad, like the distal 
section of an antler of a deer of the genus Rusa, and in the bicar- 
inate instead of tricarinate subgenital plate of the same sex. 
The supra-anal plate of the male is of the same elongate, greatly 
produced type said to occur in harpago. The form of the anal 
segment is so distorted from drying, the type having been in a 
liquid preservative, its exact form is hard to ascertain.

Size small: form compressed. Head with the occiput and vertex moder-
