Chrosiothes conservaticus Chamberlin and Ivie, 1936, Bull. Univ. Utah, 
biol. ser., 3(2): 32, pi. 10, fig. 81, 2. Female holotype from Barro 
Colorado Island, Panama Canal Zone in the American Museum of 
Natural History, examined, new synonymy. 
Theridiotis probabilis, — Levi, 1954, Trans. Amer. Micros. Soc., 73: 187, 
figs. 25, 36, 37, 2. 
Theridiotis barrovosi Levi, 1954, ibid., 73: 187, figs. 13-15, $. Male holotype 
from Hernando County, Florida in the American Museum of Natural 
History, new synonymy. 
The male and female have been collected at the same locality, 
Barro Colorado Island, and their similarity indicates that they be- 
long together. Thus T. barrowsi Levi is a synonym of C. silvaticus. 
Euryopis proxima O. P. -Cambridge, which was thought to be a 
synonym of E. probabilis is, however, a separate species. Figure 26 
was drawn from Simon’s holotype. The internal genitalia are as in 
figure 37 in Levi, 1954. 
Distribution. Florida, Mexico to Ecuador.

Euryopis proxima O. P.-Cambridge, 1899, Biologia Centrali-Americana, 
Araneidea, 1: 296, pi. 39, fig. 2, 2 . Female holotype from Orizaba, 
Veracruz in the British Museum, Natural History, examined. 
Note. This species, which was considered in my previous paper to 
be the same as C. silvaticus Simon, is distinct. Though superficially 
similar, the connecting ducts of the internal genitalia are very short 
(Fig. 24) in C. proximus. The drawings were made from the holo- 
type. I have some doubt that the type locality is correct, as large 
collections from Veracruz have not revealed additional specimens.
