patella I ; metatarsus IV shorter than tibia + patella IV by one-third 

 of its own length ; first and second tarsi and metatarsi and distal end of 

 tibiae scopulate; tarsi III and IV with scopulae divided by a median 

 setose band; patella I and III armed in front (within) with a single 

 spine. 



The epigynum of Lycosa fatifera is very much like that of Lycosa 

 lenta, but is smaller, being not more than half as long, also the septal 

 piece of the guide in lenta is more than two and one-fourth times as 

 long as the cross-piece, whereas it is less than twice as long in fatifera; 

 the cross-piece is also somewhat differently shaped in the two (PI. 

 XX, fig. 8.)

It seems very probable that Hentz, in his notes on habits, has con- 

 f oimded two species under the name fatifera ; but the description and the 

 figure which he gives can hardly be applicable to any other species 

 than the one under consideration. The description and figure indicate 

 a form without distinct markings, and his statement that a "piceous 

 variety is found in Alabama, with the two first joints of the legs pectus 

 and abdomen yellowish underneath, or lighter in color," applies per- 

 fectly to some specimens of the form above described which I have 

 from this same locality, and which is very common there and must 

 have been well known to Hentz. This form fits only his description of 

 fatifera among all treated by him. The species which Hentz observed 

 living in holes in Massachusetts, and which he says is common there, 

 may have been L. aspersa {inhonesta), as has been suggested by Banks, 

 but far more likely it was arenicola, the common turret builder of that 

 region. Hentz says: "Cheliceres covered with rufous hairs," which is 

 not so in most specimens of aspersa. The strong markings of aspersa
