setae on leg I of E. criceticola bear a fringe of short curved 

 setules. These setules of E. calif ornica are stronger and much 

 longer. 



Remarks : The occurrence of one specimen with five prongs on 

 the palpal claw among the four paratypes studied might indicate 

 that this feature is quite variable. However, the same specimen 

 was anomalous in lacking the subterminala and parasubterminala 

 I on both legs. Brennan (1948) lists nine specimens in the type 

 series and states the palpal claw is rarely with more than three 

 prongs. In eastern species with a three-pronged palpal claw the 

 character is very constant. To determine whether a five-pronged 

 palpal claw represents normal variability or anomaly within E. 

 criceticola, further collections and study are required.

Description: Size: Length of the single specimen studied, 

 420; width, 225. 



Shape: Long oval. 



Gnathosoma : Seta on palpal femur strong, curved, with long 

 setules on outer curvature. Seta on palpal genu strong, curved, 

 v/ith three or four rows of long setules. Dorsal seta on palpal 

 tibia with two alternate rows of setules; lateral seta with six 

 long setules; ventral seta with long setules. Palpal claw with 

 three strong prongs ; median prong longest and strongest ; acces- 

 sories arise about a third the length of the claw from its base. 

 Galeal seta with five setules, most projecting dorsally. Chelicera 

 with typical base, only the subapical ventral tooth determinable. 

 No punctae discernible. 



Legs : Leg I with two genualae and a microgenuala, two tibia- 

 lae and a microtibiala, a rather long spur with distal microspur, 

 a subterminala, a parasubterminala, and a pretarsala. Leg II 

 with a genuala, two tibialae, a long, rather slender spur with 

 microspur proximal and slightly anterior, and a pretarsala. Leg 

 III with a genuala. Nonspecialized setae generally long with 

 long, curving setules. No punctae seen. 



Scutum: Anterior margin slightly concave between antero- 

 median seta and each anterolateral. Lateral margins short, con- 

 cave, diverging posteriorly. Posterior margin deeply convex. 

 All setae close to the margin; anterolaterals and posterolaterals
