long, with long spines, those under tibia I a little longer than the 

 width of that joint; the abdomen is shrunken. 



Sosilaus spiniger Simon. Fig. 19. 



A very striking little species; the eyes on black spots. 



Sosippus californicus Simon. Fig. 15. 



Cephalothorax entirely dark, no pale median stripe, but rather 

 paler toward margins; abdomen pale, with broad dark stripe above, 

 indented on the sides with faint pale marks, and in male with a 

 lateral dark stripe above, so the abdomen appears dark, with two 

 pale longitudinal stripes; venter pale; metatarsi and tarsi I and II 

 very long and with very long hair and long scopulas. 



Species of Becker. 



Agelena hentzi Becker. Fig. 42. 



Three specimens, one (a female) mature; a pale, moderate-sized 

 specimen of A. ncevia. 



Singa van Bruysellii Becker. 



A male, but palpus is so bent under that I cannot see the structure. 

 The head is prominent, projecting in front; femur I is hairy, with 

 only a few spines, none as long as the width of the joint; this joint 

 is very dark near the tip, darkening gradually from near the base 

 which is pale. Venter has four white spots, two a little before the 

 spinnerets and surrounded by black, and one each side of the lung- 

 slits, further apart than the other two. 



Theridium glaucescens Becker. 



Two specimens (females) ; it is what Keyserling has so identified, 

 and is not uncommon in the Atlantic States. 



Lycosa febriculosa Becker. 



This is the young of L. aspersa or L. hellus. The cephalothorax 

 with a narrow median pale line from eye-region. Abdomen with 

 outline of a basal spear-mark, and irregular dark spots behind; 

 venter heavily spotted. Legs pale, not distinctly marked, not very 

 long; sternum dark, with a median pale stripe not reaching to the tip. 



Lycosa exalbida Becker. 



This has been recorded from the United States, but erroneously; 

 it is from Brazil; it looks much like a half-grown Ardosa cinerea. 

 There is a spine at middle above on tibise III and IV, but none at the 

 base.
