94 Hentz's Descriptions of the 
which have been devoured by the spider. On examining five 
of these cocoons attached to the same web, young spiders 
were found already hatched in the lowest one; those above 
contained eggs not glued together. Whenever this spider is 
threatened, it imparts to its web a rapid oscillation, which 
causes the eye to lose sight of it. This is probably intended 
to escape destruction from the birds. ‘The male never was 
seen with a web of his own, but was often found wandering. 
Habitat. Common throughout the United States. 
44. EPETRA CAROLI. 
Plate III. Fig. 15. 
Description. Grayish ; cephalothorax black; abdomen 
much elongated behind, blackish, with the disc grayish, varied 
with darker lines; feet varied with black, particularly the first 
and second pair. 
Observations. It is not probable that this can be referred 
to E. caudata, though that species varies much in shape. 
Habitat. Alabama. September. 
Genus Puainiyra. Mihi. 
Characters. Cheliceres very short ; maxille short, paral- 
lel, truncated above ; lip subtriangular ; eyes eight, equal, all 
borne on tubercles, in two rows of four eyes each; the first 
nearly straight, placed on the very margin of the cepha- 
othorax, the second arcuated towards the first, so that the 
external eyes are widely separated from those of the first ; 
feet, the first pair larger and much longer than the rest, the 
fourth next, then the second, the third being the shortest. 
Habits. Araneides sedentary, making a horizontal web 
formed of spiral threads, crossed by other threads departing 
from the centre, and abiding on the web with its legs extend- 
ed in a straight line. Cocoon cylindrical, tapering equally at 
both ends. 
Remarks. ‘This new subgenus is probably closely related 
to Urosonvs of Latreille. The position of the eyes however
