LASEOLA ERYTHROPUS SIM., 
WITH A KEY TO THE BRITISH LASEOLAE. 
WM. FALCONER, 
Slaithwaite , Huddersfield. 
(plate V.). 
Among a number of spiders collected in the neighbourhood of 
the Lizard Pen., Cornwall, in July, 1913, by the Rev. R. A. 
Taylor, of Scarborough, and sent to me, were several males and 
three females of Laseola erythropus Sim., examples of which 
were submitted to the Rev. 0 . Pickard Cambridge. Previously 
the species had only been known from solitary males from 
three widely separated localities, the South of France. * 
Tonbridge, t and Guernsey. The females mentioned above 
are therefore new to science and of this sex I append drawings 
and description. 
Laseola erythropus Sim. (PI. V. Figs. 6-10). 
In loco cit. descriptions of the male are given, but M. 
Simon does not figure it at all and Mr. Cambridge has drawings 
only of the cephalothorax and eyes, with corresponding draw- 
ings of L. prona Hahn, for comparison. In neither place are 
the palpal organs figured or fully described. 
Male, length 2.4 mm. 
Palpal Organs of very moderate size and consisting of a 
number of lobes of varying sizes and shapes, compactly 
arranged and without projecting processes or spines 
(figs. 6 and 8). The main lobe, extending from the middle 
of the outer margin of the tarse to a little below its 
extremity, contracts gradually above into a blunt rounded 
apex (figs. 6 a and 8 a), on the outer margin of which 
are two or three minute black blunt denticulae, difficult 
to see, and less evident in some examples than in others. 
On each side of its attenuated part is a much smaller lobe 
of somewhat irregular shape (figs. 6 b and 8c). Above 
the inner one and not far from the end of the tarse is a 
small, usually darker-edged crescent-shaped mark, visible 
from the inner side (fig. 6 d). 
In the other species with a similar type of coloration, 
the palpal organs are not only quite different (vide plate 
V.), but with the tarse also form a much larger mass.
