This species is evidently widely distributed throughout Central and South America, 
and probably occurs in the Gulf States of North America, if, as is highly probable, the 
evidently immature example from Florida, described by McCook as Cyclosa thorelli®, 
_is referable to it. The latter, however, of which the scapus of the vulva of the female 
is larger, broader, and not abruptly dilate at its apex, is quite distinct from E. dllicita, 
O. P.-Cambr. The sketches given by Banks of the male palpus and vulva leave little 
doubt that his L. caudata is also identical with E. fuscovittata, Keyserl.; the lateral 
clavis on the palpal bulb of the males of this spider is also quite distinct in form from 
that of the same sex of L. illicita. 
The female varies a good deal in form, having a broad-oval abdomen when pregnant, 
while the vulva, too, though preserving its unmistakable character, is variable in 
shape.
