MARXIA.—VERRUCOSA. 481 
posterior centrals three times the Space occupied by the latter; the laterals are overhung behind by 
a sharp angle forming the termination of a slight chitinous ridge extending about halfway towards 
the posterior centrals, Anterior row strongly procurved, the centrals being twice as far from the 
margin of the clypeus as are the laterals. Boss on the base of the mandible strongly marked. Teeth 
on lower margin of the fang-groove five in number, the fourth very small. Legs short, clothed with very 
short spines; femora i. and ii. with scarcely any spines at all beneath; protarsus and tarsus i. shorter 
than patella and tibia i. Carapace very convex behind the eyes. Sternum at least one-half longer than 
broad. Colulus present.

There is some doubt as to whether the spider identified by Emerton (tom. cit.) as 
Epeira stellata (Hentz) is identical with the examples before me; these latter, 
however, agree with McCook’s description and figures of Maria stellata *. 
VERRUCOSA.

Type of Verrucosa, V. arenata (Walck.) ; of Mahadeva, M. verrucosa (Hentz). 
3g. Coxai. with a hook and femur ii. with a groove; coxa i. also with a small tubercle towards the base above. 
Coxa and femur of pedipalp with a coniform spur and chitinous ridge respectively. Tibia ii. incrassate, with 
strong, short, curved, specialized spines, and a stout spur about the middle bearing a pair of spines at its 
apex. Patella of pedipalp bearing a single apical spine ; tarsal sheath with chitinous uncus at its base. 
3 & 2. Posterior central eyes half a diameter apart, smaller than the anterior centrals. Central quadrangle 
distinctly narrower behind, not longer than broad, anterior eyes nearly one diameter apart. Posterior 
row slightly recurved, laterals almost in contact; the anteriors distinctly larger, distant from the posterior 
centrals nearly three times the space occupied by the latter. Anterior row straight or slightly recurved, 
* In Hist. Nat. Araign. 2nd edit. i. p. 801, in connection with M. stellata, there occurs a misprint— 
“recurvée” instead of ‘ procurvée.” The males of the M. stellata before me have no coxal hook on leg i., 
as stated to be the case by Simon (Joc. ct. p. 802).
