366 ARANEIDEA. 
ARTEMA. 
Artema, Walckenaer, Ins. Apt. i. p. 656 (1833). 
Type A. atlanta, Walckenaer. Brazil. 
This genus can be at once distinguished from all others of the family by the 
acuminated posterior portion of the sternum. Only one species occurs in Central 
America, and it is quite cosmopolitan, being found all over the Neotropical and 
Paleotropical Regions. This spider has been described under various names by 
different authors; but having minutely examined numerous examples of it in the 
British Museum Collection, from the Antilles, the Amazons, Mauritius, East Indies 
(Karachi and Poona), and the Malay Archipelago, 1 am convinced that they are 
identical. There are slight individual differences, it is true, in the form of the 
chitinous processes on the male palpus, and also in the exact position of the eyes, 
but these characters cannot, in my opinion, be regarded as of specific importance. 
E. Simon considers A. atlanta and A. mauriciana to be different species; but 
examples from St. Vincent (Antilles), identified by him as A. atlanta, are identical 
with others received from Mauritius, and also with the large number taken by me at 
Santarem, on the Lower Amazons.
