Pseudorhicnoessa spinipes Malloch ,

Mus. Nat. Hung., Ann. 12: 307, 1914.

Originally described from Formosa. In the present collection there are specimens from Agat and Inarajan, those from Inarajan collected on seaweed, Usinger .

This species may occur on the seashore of other islands in the Indo­ Australian region, but collecting on the proper locations will be essential to the discovery of specimens as they seldom leave their special habitat.

A series of both sexes of this species shows that there is but little variation in either color or structure from my description of the female type specimen. It may be noted here, however, that I omitted mention in my description of a series of short, fine, erect, closely placed stiff hairs on the apical third or more of the anteroventral surface of the fore femora.
