 on the back is very distinct. The mandibles of the male, Fig. 1, 

 are larger and darker than those of the females and have a large tooth 

 on the front inner corner. The tarsal hook of the male })alpiis is

Length, 2 '5'"'" to 3""". Legs aiid cephalothorax brownish yellow, 

 cephalothorax with dark edges. Abdomen dark gray. A slightly 

 larger and darker species than viaria. The upper fold of the epigy- 

 num is narrowed toward the end and transversely wrinkled like the 

 hook of the e|)igynutii of some Epehuv. Fig. 2b. The male palpus 

 has the tarsal hook wide and blunt with a curved ridge on which is 

 a row of teeth. Fig. 2. The most characteristic part of the palpal 

 organ is a row of five short teeth on the middle. Fig. 2a. Under 

 this is the large, dark brown part, with a sharp spine directed for- 

 ward and two blunt spines toward the base. The inflated tube lies 

 between this and the tarsal hook.

Length, about 3'"'". Cephalothorax and legs light orange-brown.

 the eye-area and rounded in front. The femora of all the legs are 

 stout. The tarsus of the male palpus has a prominent process on the 

 edge just over the tarsal hook. The tibia is unusually thick and with- 

 out any hook. The tarsal hook is large and strongly curved, the 

 end is flat and wide, and divided into two teeth, one twice as large as 

 the other. Over the hook is the end of a large appendage of the 

 palpal organ fringed with fine teeth.
