Observations. This spider is usually found on blossoms, 

 watching for prey, in the manner of Thomisus. It seems per- 

 fectly distinct from 31. carolinensis, but specimens occur -in 

 which the cephalothorax is much wider ; is it owing merely to 

 the state of the abdomen, which has become narrower when 

 the eo-o-s are laid? It makes no web, but, when attacked, 

 it leaves a thread behind. This is a common species, which 

 does not reach the size of D. carolinensis. 



Habitat. Alabama. All seasons. 



[PL 18, fig. 98, tropin. This species differs from M. caroli- 

 nensis in its anterior eyes, which are in a straight line and by 

 its cephalothorax, which has one broad band ; the abdomen has 

 two hairy elevations anteriorly. Supplement.'] 



2. Micrommata serrata.

PL 6, fig. 8. 



Description. Pale yellowish gray ; cephalothorax with two 

 parallel, longitudinal, narrow, greenish bands ; abdomen with 

 a narrow, scalloped, brownish band above, beneath with two 

 longitudinal blackish lines, approaching each other, and becom- 

 ing narrower towards the apex ; feet slightly marked with 

 grayish rings, in all specimens, 2. 1. 4. 3. A small species. 



Observations. This singular little spider is commonly found 

 on plants, particularly on broad leavqs, more abundantly in 

 damp places. It spreads its feet, and seems fond of basking in 

 the sunshine. Its webs are various ; sometimes it throws out 

 only a few threads on the upper surface of a leaf; at other 

 times, it makes a web in the tops of bushes, like that of several 

 species of Theridium ; and it has also been found in a web 

 similar to that of Agelena, but open equally at both ends. I 

 had once supposed that this might be the young of M. imdata ; 

 but I am convinced it is a very distinct species, never acquiring 

 a lame size. 



Habitat. North Alabama. Summer.
