A REVISION OF THE PISAURIDAE OF THE UNITED STATES 5) 
Dolomedes tenebrosus, p. 501, pl. 49, figs. 9, 9a, 9b,

of Dolomedes vittatus Walckenaer; figure gc is the epigy-

Dolomedes sexpunctatus, p. 210, pl. 7, figs. 6, 6a, 6b. 
I am inclined to believe that figure 6 represents an immature female 
of Dolomedes striatus Giebel; at least it has the markings 
of this species. Figures 6a and 60 represent the palpal organ and 
dorsal aspect of Dolomedes triton Walck. 
Species of Keyserling

Tetragonophthalma undulata. This species does 
not belong in Tetragonophthalma nor in Thanatidius of which T. 
dubius Hentz is the type. It is regarded in this revision as the 
type of a new genus. 
Species described or mentioned by Simon

Maypacius floridanus Simon is very probably the 
species described by Hentz as Thomisus tenuis. Goes in 
the genus Thanatidius.

Thanatidius dubius. Simon selected Thomisus 
dubius Hentz as the type of the genus Thanatidius but gave a 
description of the species earlier described by Keyserling as 
Tetragonophthalma undulata. Keyserling’s species 
did not belong in Tetragonophthalma and Simon’s name (Thana- 
tidius) must be retained because the type (Thomisus dubius 
Hentz) was designated.
