Tribe VII. not determined ; eyes in four rows. 



11. Thomisus? dubius. 



PL 10, fig. 11. 



Description. Pale ; cephalothorax with two slender longi- 

 tudinal blackish lines edged with greenish ; abdomen with a 

 similar green edged line, which bifurcates towards the base, 

 and has one small black dot on each bifurcation ; feet, first 

 pair wanting, second very long, fourth next, third shortest. 



Observations. This singular spider was unfortunately muti- 

 lated when discovered, and the drawing was left unfinished, 

 as I hoped other specimens would occur ; none, however, were 

 ever found. There is an affinity in some points between this 

 and T. Duttoni. 



Habitat. North Carolina. [449.]

12. Thomisus ? tenuis. 

 PI. 10, fig. 12. 



Description. Testaceous, downy ; cephalothorax with a lon- 

 gitudinal white band, and a tuft of hair between the eyes ; ab- 

 domen with two interrupted longitudinal whitish fillets, four 

 long nipples ; feet bristly, 2. 1. 4. 3. 



Observations. This is undoubtedly congeneric with my 

 Thomisus dubius. But knowing nothing of their webs nor of 

 habits, I still refrain from making any generic distinction. 

 These will probably form the type of a new sub-genus. This 

 one was found enclosed in the clay nest of a Spex. 



Habitat. Alabama. 



[PI. 18, fig. 84, eyes ; fig. 101, tropin. The two anterior
