is covered with short, stiff, black hairs directed upward. PL II, 

 Figs. 4, 4 a. The first and second legs have similar short, stiff hairs 

 on the under side. On the femur the hairs are clustered at the 

 base and are smaller and in two rows toward the tip. On the 

 tibia they are longer and in eight or ten pairs, and on the meta- 

 tarsus and tarsus the}' are finer and more like ordinar}' hairs. The 

 first and second legs are slightly thicker than the others. The 

 cephalothorax is as wide as it is long. The sternum is as wide as 

 long, and extends between the fourth legs where it is as wide as 

 one of the coxas. The male palpi are short with the patella about 

 twice as long as wide and widened at the end. The tibia is not 

 widened laterally but extends upward over the tarsus, ending in a 

 slightly curved tip on which is a small incurved point. Figs. 4, 4 b. 

 The tarsal hook is simple in form, and its base follows the curve 

 of the tibia. The tube of the palpal organ is long and slender, 

 and makes one turn around the end of the bulb, supported at the 

 end b}' a thin appendage half its own length. Fig. 4 b. 



The female is the same size and color as the male and has the 

 head a little elevated, but no unusual arrangement of hairs on the 

 head or front legs. The epigynum is short and wide, showing- 

 through the skin round receptacles more than twice their diameter 

 apart. Fig. 4 c.

Lophocai'enum domiciliorum, new. 



From cellar of Boston Society of Natural Histor}-, November, 

 1910. The head is only slightly elevated behind the e3'es. The 

 upper row of eyes, seen from above, is nearly straight. At the 

 sides of the head beginning just behind the upper lateral eyes are 

 deep grooves extending backward half the length of the head, with 

 shallow and pointed pits near the anterior end. PL II, figs. 5, 5 a. 



The male palpus has the patella as long as wide and the tibia 

 a little longer, widened at the anterior end, with a long, sharp point 

 on the inner side. The tarsus is oval and the palpal organ small 

 and simple. Figs. 5 b, 5 c. 



During the autumn flights great numljers of small spiders are 

 1)lown into Boston and alight on the fences of the common and 

 the streets west of it. This spider probably came into the cit}' in 

 this wa}-.
