Cambridge had but one species of Marxia from Central 
America when he defined the genus and he states that the 
species identified as stellata from Mexico and Guatemala 
may not be the same species as figured by Emerton in 
the Epeiridae of New England, 1884. 
Acanthepeira venusta differs from the generic descrip- 
tion as given by Cambridge in three structural characters. 
The p.m.e. are larger than the a.m.e. ; the quadrangle is 
as wide behind as in front, and it is distinctly longer 
than wide ; the lower margin of the fang groove has four 
teeth. 
The males of A. venusta can be separated from A. stel- 
lata by the narrower abdomen with the terminal tubercle 
turned upward, the much narrower ventral apophysis on 
the tibia of the palpus and the paracymbium. The fe- 
males can be separated from A. stellata by the narrower 
abdomen and the epigynum.
