Fig. 4. Legs liglit yellow wkli Mack rings, three on the femur, 

 and three on the tibia. The abdomen is white with five or six ])jiirs 

 of black S[)ots along the middle, from which lines of irregular spots 

 extend obliquely down the sides. Beneath the abdomen is spotted 

 and there are black spots on the sternum in the middle and at the 

 bases of the legs. The mandibles and maxilhe are very small. Tliere 

 are only six eyes. The middle pair are close together near the front 

 edge of the head over the mandibles. The lateral eyes are higher 

 and farther back. The male differs but little from the female. The 

 male's palpi are stouter than the female's. The tarsus has a long 

 process on the upper side. The bulb is round with a narrow por- 

 tion extending as far as the tarsal i)rocess and there narrowing into 

 a fine long tube. The whole palpal organ is as long as the rest of 

 the palpus. 



This is another house spider, perhaps imported from Europe. It 

 is found in cellars and shaded corners in rooms. 



Ceratlnella. 



Geratina Menge, Preussisclie Spinnen. 



This genus, like Pholcoinma, has tlie upper part of the abdomen 

 thick and hard, and hard spots around the pedicel and the spinnerets, 

 but this sometimes is only found in one sex. The cephalothorax and 

 abdomen are both short and round. The heads of the males are 

 usually higher than those of the females and in some species very 

 large and raised into humps. The ])alpal organs are much alike 

 throughout the genus. Tlie tube is divided into two parts, appearing 

 as if liroken near the middle, and the corners near the bi-eak are 

 sometimes lengthened into teeth of ^ arious shapes. At the base of 

 the bulb is a long hard )»rocess, pointing backward. The tarsal hook 

 is small and simple. The til)ial hook is large aiul extends outward 

 from the palpus, varying in shape according to the species. The 

 length of the patella varies greatly in different species. All the 

 species are very small, 1 to Ji""", and are found either under leaves or 

 in summer on low plants.

 This is of the same size and color as C. ^/issice/is, usually a little 

 lighter orange with a smaller black mark on the head which seldom 

 extends backward on the middle of the thorax as in ^A\s.s?'cf7)s. The
