Second Contribution to Spider Fauna of Scotland. 187 
first and second tibie lack the posterior lateral spines which occur in some 
species of this genus but which are again absent in MZ. rwrestris and M. sublimis. 
The only means of recognising the females of this species appears to be 
by the relations of the eyes. 
In M. rurestris and M. sublimis the posterior row is practically straight. 
The eyes are practically equal and equidistant. If there is any difference 
the centrals may occasionally be very slightly larger, and very slightly nearer 
the laterals than each other. 
In M. nigripes the posterior row is fairly distinctly curved in a line 
concave in front. The centrals are much larger than the laterals, and much 
* nearer to them than to each other. The centrals are very large and round 
and generally have a pearly lustre. 
I don’t know whether this is invariable, but it obtains in all of the dozen 
examples I have seen. 
M. nigripes Sim. has only hitherto occurred on the French and Swiss Alps 
at high altitudes. Dr de Lessert found it under stones up to 2800 metres. 
He states that the male becomes adult in August. I only found one example 
of this sex, the remainder being females with egg sacs. This is of course the 
first British record. 
Dismodicus elevatus C. L. K. 
[Plate V. Figs. 3 and 5.] 
As stated above, I obtained a single male of this well-known continental 
species in Abernethy forest where it was beaten from a juniper bush. 
It differs distinctly from the common JD. bifrons BI. in caput and palpi. 
My specimen is rather larger than the average of that species, measuring 
1:85 mm. in total length. D. bifrons Bl. does, however, reach this sometimes. 
Looked at from the side the caput of D, elevatus is higher, more massive, 
and more globular than that of D. bifrons. From above, the sides appear 
much more convex and the two lobes much more divergent posteriorly. The 
sides appear very convex, again, when seen from the front, and the central 
depression between the lobes is less evident. The palpal differences are even 
more marked. 
In D. elevatus the tibia seen from above is very broad, and its external 
apical angle is produced into an apophysis directed upwards and outwards 
and very visible from the inner side of the organ. As there seem to be no 
figures of the tibia in the latter position I give some, and also show the base 
of the tarsus. This, in D. elevatus, is produced backwards and downwards on 
to the inner side of the tibia as a curved apophysis.
