Further Notes on Dyscritina 883 
locality there appear to be two distinct species. Not 
being properly conversant with the important points of 
the Forficulide, I will not myself attempt a formal 
description, but content myself with noting some general 
characters by which the two species may be distinguished. 
They may be separated roughly by the structure and 
proportionate length of the caudal appendages in the 
larval stages. 
In the typical form, D. longisetosa, the cerci are con- 
siderably longer than the body of the insect, cylindrical, 
multiarticulate, with many fine longish backwardly- 
directed hairs amongst the shorter pubescence (Figs. 
4, 16). 
In the new species these appendages are always shorter 
than the body of the insect, with comparatively few joints, 
tapering and with a few stout forwardly-directed spines 
amongst the shorter pubescence (Figs. 2, 15). 
The general coloration of the two species is also different. 
In its larval stage D. longisetosa may be readily distin- 
guished by its paler tints, the abdomen being straw- 
colour with brown transverse bands (Fig. 4). The larva of 
the new species (Fig. 2) is of a more uniform blackish- 
brown colour, and the femora are more distinctly banded. 
‘In both species the hinder angles of the prothorax are 
ornamented with well defined straw-coloured patches 
(Fig. 2, 4). 
The imago of DP. longisetosa varies in colour from 
castaneous to bright fulvous. In the darker form the 
prothorax bears a conspicuous blackish curved fascia on 
each side (Fig. 5). The paler variety usually has a 
diffuse brownish fascia upon the middle of the elytra. 
In the new species the general tint is blackish brown. 
The female (Fig. 3) is more suffused with castaneous, the 
elytra are more conspicuously reddish. 
The male insect is distinguished by the greater number 
of abdominal segments (Fig. 6). 
On Oct. 27, 1897, a pair of this new species, reared up 
in captivity, were found in coitu. The abdomen of the 
male was twisted round and the extremity was closely 
applied to the undersurface of the pygidium of the 
female. 
The first eggs were deposited on November 4, and 
others were added at intervals during the following week, 
until a total of twenty-five had been laid. The eggs were
