 with tarsus — 4.3 mm., total — 10.5 mm.; Second leg, femur — 

 2.9 mm., tibia with patella— 3.0 mm., metatarsus w4th tarsus — 

 4.3 mm., total — 10.2 mm. ; Third leg, femur — 2.6 mm., tibia with 

 patella — 1.8 mm., metatarsus with tarsus — 2.3 mm., total — 

 6.7 mm. ; Fourth leg, femur — 3.4 mm., tibia with patella — 

 2.3 mm., metatarsus with tarsus (broken ofif very near its distal

One specimen from Florissant, No. 13523 (now No. 107) in the 

 Scudder Collection of the ]\Iuseum of Comparative Zoology of 

 Harvard University. 



Scudder's description is correct. The pedipalpi are absent, but 

 the shape of the body and the proportion of the legs leave little 

 doubt as to the sex of the specimen.
