Superfamily Argiopoidea 



median eyes; and the anterior row of eyes is but little longer 

 than the row formed by the posterior median eyes. 



This species may be the Lycosa triton of Walckenaer as 

 suggested by Petrunkevitch Cioa); but it does not seem wise to 

 me to change the name at this time. It is quite possible that 



the two types described above 

 represent distinct species, and 

 that one may be termed D. triton 

 and the other D. sexpundatus.

 DOLOMEDES SEXPUNCTATUS 



Dolomedes tenax (D. ten'ax).— This is a small spider de- 

 scribed by Hentz (44) from North Carolina. He represents 

 it as one fourth inch in length. The species is unknown to me. 

 I therefore copy his figure (Fig. 709) and quote the original 

 description which is as follows: 



"Description. — Grayish; cephalothorax edged with black, 

 varied with blackish on the disk; abdomen also edged with black 

 near the base, varied longitudinally, with blackish on the disk, 

 about three whitish dots on each side near the apex, pale beneath, 

 with two obscure longitudinal lines; feet, with blackish bands 

 above, pale beneath. 4. 2. 1. 3. Never large." 



"Observations. — This distinct species is always found on 

 upright sticks, small trees, etc., turning round to avoid an attack 

 in the same manner as Oxyopes scalaris, which it resembles so 

 much that for a time I could not distinguish one from the other. 

 It spreads its feet like Thomisus. The form of its cephalothorax 

 is peculiar, the head being elevated and well-defined from 

 the thorax. It must not be mistaken for the young of D.
