projection are the mandibles which are very small. The maxillae 

 are inclined toward each other, over the short and rounded labium. 

 The sternum is as wide as long. The abdomen is oval, as wide 

 as the cephalothorax, and one-half longer. It is marked with irreg- 

 ular opaque white spots, a black line around the front end and 

 several pairs of black spots, Fig 1. The shape of the end of the 

 abdomen and the arrangement of the spinnerest are very peculiar 

 in this genus. At the end of the abdomen behind the anus is an 

 oval appendage surrounded by a single row of curved hairs of the 

 same thickness throughout their length, and rounded at the end. 

 The hinder pair of the spinnerets are their length apart, and extend 

 backward so as to be seen for nearly their whole length from above. 

 The spinning tubes extend along the under side. The cribellum is 

 slightly divided by a notch in the middle. The calamistrum consists 

 of two parallel rows of ten or twelve sligthly curved hairs, extend- 

 ing half the length of the fourth metatarsus. The legs are all about 

 the same length, and the feet have three claws. The epigynum 

 has a double tube directed backward and resting in a shallow 

 groove on the under side of the abdomen. The male has the legs 

 longer and the abdomen smaller, but otherwise resembles the fe- 

 male. The male palpus has very short patella and tibia, and the 

 tarsus is wide and oval, and the palpal organ thick and furnished 

 with a cluster of short appendages near the base. 



This (Ecofnus lives in houses and on walls and fences. It makes 

 a flat web one to two inches long and half as wide, fastened at 

 several points around the edges, leaving open spaces through which 

 the spider can run in and out. The spider stands on the wall be- 

 hind and not on the web. 



It has been known since the time of Hentz in the Southern States, 

 but has lately been found in a house in koxbury, a suburb of Boston, 

 where it seems to be well established around window frames and 

 behind furniture.

 1.5 mm. to 2 mm. long and pale and translucent without any 

 markings. The cephalothorax is shaped like that of amaurobius. 

 The abdomen is slightly larger and wider than the cephalothorax 

 and a little wider behind than in front. The eyes are six in number, 

 large for the size of the spider, all about the same size and arranged 

 in two groups. The cribellum is small, about as wide as one of
