Spiders and Their Near Relatives 



Genus PHALANGIUM (Pha-lan'gi-um) 



The last segment of the pedipalps is longer than the penul- 

 timate, and the femur of the pedipalps is not furnished with 

 prominent spines; there is a group of spinules on the anterior 

 margin of the cephalothorax and the eye-tubercle is spinose; and 

 the femur of the first legs is longer than the width of the body. 

 Two species occur in the United States. 



Phalangium longipalpis (P. lon-gi-pal'pis). The palpi are 

 very long, in the male they are longer than the body, in the 

 female they are longer than the width of the body; the second 

 segment of the chelicera of the male is prolonged above in a spur, 

 that of the female is normal. The length of the body is a little 

 over one fourth inch. The species was described from Arkansas. 

 it occurs abundantly in New York. 



Phalangium cinereum (P. ci-ner'e-um). — The palpi are much 

 shorter than in the preceding species, in the female they are 

 scarcely as long as the width of the body; the chelicerae of the male 

 are normal. The length of the body varies from one fifth to a 

 little more than one fourth inch. 



This species is widely distributed in the Northern States. 

 Weed in writing of it states as follows: 'This species is pre- 

 eminently what may be called an indoor form. It abounds 

 especially in sheds, outhouses, and neglected board-piles, being 

 rarely found in the open field. Its colour especially fits it for 

 crawling over weather-beaten boards, making it inconspicuous 

 against such a background. During the day it is usually quiet, 

 but at dusk and on cloudy days it moves about quite rapidly." 



Genus M1TOPUS (Mit'o-pus) 



The harvestmen of this genus agree with Phalangium in the 

 characteristics given above except that the femur of the first legs 

 is shorter than the width of the body. Three species occur in 

 our fauna. 



Mitopus californicus (M. cal-i-for'ni-cus). — The tibia of 

 the second legs is much longer than the metatarsus of these legs; 

 there is one false articulation in the metatarsus of the first legs; 

 and the eye-tubercle is about its diameter from the anterior 

 margin of the carapace. The species occurs in California.
