300 Mr. J. W. Douglas’s Observations on the 
is distinctly visible throughout, the cereous matter 
taking the form of each segment; the body in early life 
flat, afterwards distended ; the seement next to the frontal 
node entire, the rest divided by a median impressed line, 
on which, in the first three of the divided segments, is a 
very small scutelliform nodule, and at the end of the 
line, immediately adjoining the lamine of the circum- 
ference, is a short somewhat elevated lamina arising at 
the anal orifice and projecting over them. ‘The mar- 
supium is short (varying in length), broad, the posterior 
angles rounded off; the upper surface, arising below the 
circumferential border, but distinctly separate from it, 
nearly flat, having only eight or nine slightly raised 
longitudinal lines; the lower surface, arising at the 
posterior coxz and hiding the abdomen, convex, perfectly 
smooth, the end curved upwards. Antenne and legs 
pale piceous. Sometimes the upper surface, more rarely 
the lower also, assumes a smoky hue. 
In the first days of April last, Mr. George Norman 
found, about the base of the stems of grass and Carex 
growing-among long damp moss at Pitlochry, in Perth- 
shire, some hibernated examples of this species, male 
and female, the latter having then no development of 
marsupium: these I failed to keep alive. In May, I 
received from the same gentleman, a supply of females 
with the marsupium partly, rarely fully, developed, and 
also two or three males. Some of these I managed to 
keep alive until the 12th of June, when a part of the 
females had the marsupium quite developed and full of 
white eggs, and a part still remained with only a small 
marsupium ; the males being but little increased in size, 
and at most but 1} line long. Mr. Norman tells me that 
young ones began to appear in the first week of June, 
and from the first had the scale-like covering. The 
same curious question also arises with this species as 
with O. wrtice, namely, why the males co-exist with the 
gravid females? and it is also unknown if any winged 
males ever appeay.
