Superfamily Argiopoidea 



eyes are farther apart, the lateral eyes are not on tubercles, and 

 the legs are less slender. 



They vary in colour from tawny to dark brown. Their webs 

 are tiny sheets of silk usually made under stones or at the base 

 of herbs, and rarely attract attention. 



A single species, Tmeticus armatus, has been described from 

 our fauna; this is found in Canada. 



Genus MICRON ETA 

 (Mi-cron'e-ta) 



The members of this genus 

 are small spiders of slender form 

 with long and slender legs. They 

 agree with the preceding genus in 

 having nearly square endites (Fig. 

 388) and in that the tibiae are with- 

 out lateral spines; but differ in 

 that the clypeus is more or less 

 depressed below the eyes, the pos- 

 terior eyes are close together, the 

 lateral eyes are on slight tubercles, 

 and the legs are longer and more 

 slender. 



A score of species are known 

 mjcroneta unimaculata f rom the United States ; but as most 



of the species have been collected 

 by sifting dead leaves, comparatively little is known regarding 

 their habits. The species are mostly black or reddish or greenish 

 brown. 



Genus BATHYPHANTES (Bath-y-phan'tes) 



With this genus begins the series of genera of the Linyphiinaj 

 in which the legs are long and are furnished, at least on the tibiae, 

 with superior and lateral spines; and in which the metatarsi are 

 as long as or longer than the tibiae. 



In Bathyphantes the sternum is heart-shaped, the median 

 ocular area is not longer than wide, and the metatarsi are un- 

 armed. 



These are small spiders; they are found under stones or leaves, 

 and at the base of plants, where they spin a very delicate sheet.
