Titanceca Thorell. 
Titanceca americana, new sp. 
Pu. X, FIGURES 4 TO 4d. 
This spider resembles 7: guadriquttata of Europe, but is usually 
without markings on the abdomen. The female is 5 or 6™™ long, re- 
sembling in size and shape the common Steatoda borealis, from which, 
however, it is readily distinguished by its black color. 
The cephalothorax is dull orange-color, blackish around the edges 
and toward the front. The rest of the body is deep black and cov- 
ered with long hair, except in some individuals a few light gray spots 
in pairs on the abdomen. 
The sternum is as wide between the second legs as it is long. The 
labium is as wide as long, a little narrowed and rounded at the tip. 
The maxille are nearly straight on the inner edges not curved in- 
ward at the tips, as in Amauwrobius. The head is not so wide as in 
Amaurobius. The eyes have nearly the same arrangement, but are 
proportionally larger. PI. x, fig. 1. The spinnerets are short. 
The cribellum is divided in the middle as in Amaurobius, and the 
calamistrum is like that genus. 
The claws of the feet are large and strong, proportionally larger 
than those of Amaurobius. 
Like most of the genus, this lives under stones in the driest and 
hottest places. Under the loose stones under the trap hills around 
New Haven and Meriden, Conn. it is common. Ihave a few from 
Mt. Monadnock, N. H., but have not found it elsewhere in New 
England. 
Titanceca brunnea, new sp. 
Pu. X, FIGURES 5 TO 5c. 
This species is about as large as 7. americana, but is a little more 
slender and less hairy. The cephalothorax is light or dark brown, 
like dead oak leaves among which it lives. The joints of the legs 
are darker toward the distal ends. The abdomen is similarly colored, 
but becomes redder than the rest of the body in alcohol. Across the 
back are four or five lines of light yellowish spots, and there are 
larger irreguiar spots along the sides, as in many species of Dictyna. 
PI. x, figs. 5, 5a. Under the abdomen between the spinnerets and 
epigynum are two large light spots. Fig. da. : 
Besides the color, the only plain difference between this and the 
black species is in the palpi of the female, which in this species have
