Genus Herpyllus. Mihi. 

 Silliman's Jour., Vol. xxi, p. 102. 



Characters. Cheliceres moderately/ large, without teeth ; max- 

 illce 2)arallel, wider above the insertion of the palpi, cut obliquely 

 above; lip about half the length of the maxilla;, narrower to- 

 wards the point; eyes, eight, sub-equal in two parallel roivs of 

 four each, both commonly bent totvards the base ; feet, the fourth 

 pair longest, then the first, then .the second, the third being the 

 shortest. 



Habits. Araneides wandering after prey, making no web, 

 but running about with great swiftness, and hiding under 

 stones, in crevices, etc. Cocoon unknown. [455. j 



Remarks. This sub-genus, very closely related to Clubiona, 

 is very well characterized notwithstanding the similarity. The 

 character derived from the respective length of the legs is veiy 

 constant, showing the property of being fast runners in all the 

 species of this division. 



In habits they differ wholly from Clubiona, being in fact 

 wandering Araneides. The swiftness with which they run is 

 truly surprising. They are not exclusively nocturnal, being 

 often seen to run in the brightest sunshine. 



Tribe I. Brevipedes. Legs strong, rather short, maxillce 

 long, cut obliquely above. 



1. Herpyllus ecclesiasticus. 

 PL 11, fig. 2.

 tudinal band; abdomen with an abbreviated band, and a spot 

 white. 



Observations, This spider is not rare, found between boards 

 and in crevices in dark places ; running very fast, chiefly at 

 night ; I never could find its cocoon or its permanent dwelling- 

 place.
