ART. 13. NEW AMERICAN AND CHINESE SPIDERS CHAMBERLIN. 27 



Family LYCOSIDAE. 



SOSIPPUS MIMUS, new species. 

 Plate G, fig. 43. 



Female. — Integument of carapace black, in life largely concealed 

 on sides of thoracic division with grey hair; head with a fine light 

 colored median longitudinal line with a similar line on each side 

 diverging caudacl from between the eyes, these lines clothed with 

 somewhat orange-colored hair, hair of similar color being also present 

 on sides of head. Sternum brown. Integument of legs brown, not 

 annulate, clothed with finer gre}" hair and coarser black hair, the 

 grey hair disappearing distally and appearing along dorsal surface 

 of metatarsi in a series of spots, the scopular black as usual. Abdo- 

 men clothed above with grey and black hair, the dorsum showing a 

 basal spear-mark furcate behind, each point of the furcation being 

 followed by a series of confluent black spots, those of each side con- 

 nected by fine chevron lines ; lower part of sides showing some brown ; 

 venter caudad of epigastric furrow with two black lines that con- 

 verge caudad and almost meet, thereafter running parallel to each 

 other. 



Anterior row of eyes decidedly longer than the second row, pro- 

 curved, nearly equidistant, the laterals distinctly more than their 

 diameter from the lower margin of the clypeus. 



Lower margin of furrow of chelicera with three stout teeth. 



Tibia III and IV with a setiform spine in median dorsal line at 

 base, this distally fine, but none at middle or distal end. 



Epigynum somewhat resembling that of Sosippus fioHdanus Simon 

 (pi. 6, fig. 43). 



Length, 18 mm.; cephalothorax, 9.2 mm.; tibia and patella I, 7.5 

 mm. ; tibia and patella IV, 9 mm. 



Locality. — Louisiana : Mandeville. ' H. E. Hubert. May 1, 1921. 

 Two females. 



Type.—C^t. No. 1012, M. C. Z. 



This species might seem to be atypical in possessing only three 

 teeth on the lower margin of the furrow of the chelicera. However, 

 it shares this character with the Costa Rican S. agalenoides ; and as 

 the number of teeth varies on the two sides in some individuals of 

 S. fioridanus, it is not thought that this character by itself is a 

 reliable generic index. 



The field note states that the two specimens of the present species 

 were taken in a funnel web, indicating that the species conforms in 

 habits to the others previously observed.
