our specimen the head has dark post-ocular bands, bordered dor- 
sad by a slightly paler shade than the general pale brown and 
iinmaculate coloration of the other portions of the insect. 
As we have already noted, the genus OcuophiJa Brunner was 
based on an aggregation of twentj'-nine species, many of which 
represent distinct generic units. Compared with the genotype, 
the present insect is seen to differ in the much more elongate 
head and apex of subgenital plate, which shows a small l)ut deep 
median emargination. The form of the head agrees fully with 
the usual type developed in Lihethra, while the distal portion of 
the abdomen shows a similarity of general structure, though by 
no means as highly specialized, with distal abdominal tergite 
no wider than long. 
As this species evidently belongs to the phylum which includes 
Lihethra and not to the phylum which includes Ocnophila as 
properly restricted, we here assign reservata to the genus Lihethra. 
Study of more material, we believe, will probaldy show that the 
insect is a member of a distinct generic unit. At the present time 
insufficient material is at hand to solve this problem, but we 
believe it best to transfer the species to the genus which includes 
forms of clearly nearer relationship. In fact the male before us 
might easily be supposed to represent some species of Lihethra 
in one of the later instars preceding maturity. This, however, 
we believe is disproven by the well formed, strongly in-bent cerci, 
which in the in-bent portion taper strongly to their blunt apices 
and are thickly supplied with short stout chitinous teeth.
