Note. The similarity of my illustrations of the female types of the 
two names was not noted until some time after the examination* 
Keyserling’s descriptions, except for the color of the abdomen, are also 
similar. Although rotundum has page priority, the name Chrysso 
nigrosternum Keyserling is used here, because the male palpus is very 
distinct while the epigyna are not. Figures n, 12 were made from 
the type of T. rotundum , Figures 9, 10, 13 from those of C. nigro- 
sternum.
