Spaaes 1 4. They are closely allied to each other and con- 
stitute a natural group. Three features are especially characte- 
1 istic: the anal plate is almost only constituted of branches, it 
being cleft in the median line almost to the base; the anterior setæ 
°n the sternum of the anal segment are longer and stronger than 
in any other species; the lower antennal branch increases less in 
breadth towaids the end than in the following species, and its po- 
stenor 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 clavate, and the intermediate pair in the fourth row is 
\eiy 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 paiis; the last pair of legs are long or rather long. The 
species are s large. — To this group belongs a fifth species descri- 
bed by Kenyon as P. Huxleyi (see „ remarks“ on this species).
