Species 1—4, They are closely allied to each other and con- 
stitute a natural group. Three features are especially characte- 
ristic: the anal plate is almost only constituted of branæhes, it 
being cleft in the median line almost to the base; the anterior setæ 
on the sternum of the anal segment are longer and stronger than 
in any other species; the lower antennal branch increases less in 
breadth towards the end than in the following species, and its po- 
sterior margin is only a little or even slightly longer than the an- 
terior. Most of the hairs on the upper surface of the head are 
strongly elavate, and the intermediate pair in the fourth row is 
very long; the upper antennal branch is several — from five to 
eight — times longer than broad. The setæ on the posterior ;seg- 
ments of the trunk are at least moderately long; the distance be- 
tween the submedian setæ on the tergum of the anal segment is 
considerably longer than between the submedian and. the inter- 
mediate pairs; the last pair of legs are long or rather long. The 
species are large. — To this group belongs a fifth species descri- 
bed by Kenyon as P. Huæleyi (see ,,remarks" on this species).

Material. Some specimens from Denmark, a' few animals from 
Germany and one from Italy. — In some of the structural features 
I have found variation, which will be treated separately, but in the 
description of the species the essential differences between the spe- 
cGimens have been taken into consideration. 
Head. The eyes are smaller than in St. pedunculatus, rather 
Narrow, and the distance between them is almost one third longer
