together, and hatch early. Many cocoons are frequently 
seen on the same web, though usually there is but one at a 
time with eggs, the others being previously vacated. This 
proves the immense propagation of this common tenant of 
our houses. 
This spider differs from some other species in its never 
concealing its home in holes or crevices. 
Habitat. All the United States. 
2. THERIDION SERPENTINUM. 
Plate IX. Fig. 2. 
Description. Rufous; abdomen yellowish glossy, with two 
winding lines, connected with the sides, black ; varied with 
black underneath; feet 1. 4. 9, 3. 
Observations. This spider was brought to me from Geor- 
gia by Mr. Thomas R. Dutton. A specimen very much 
resembling this was found in Alabama, but the trophi were 
those of Theridion studiosum, which is not as large a species 
as this, 
Habitat. Georgia. 
3. THERIDION MARMORATUM. 
Plate IX. Fig. 3. 
Description. Rufous; abdomen with two impressed dots, 
whitish, varied with spots and veins black, base whitish, 
piceous underneath with a few obsolete pale dots; feet 
li 8. 3. 
Observations. This spider, though closely related to T. 
boreale and T. serpentinum, departs from the characters of 
this subgenus by its trophi, which are those of Epeira, by a 
strange anomaly. It is not uncommon under stones. The 
mouth was examined several times and always presented the 
character of Epeira. It was always found under stones. 
Habitat. Alabama. March, June.
