covered with large setules which tend to stand out in a frill on 

 the basal half. Sensiilae usually broken off. Anterior to each 

 pseudostigma is a wide inverted U-shaped ridge, the inner leg 

 terminating medial to the pseudostigma, the outer leg extending 

 to the posterior margin; often obscured. Surface punctate. 

 Usually a pair of pits larger than punctae near the ridge medial 

 to each posterolateral seta. 



Summary of standard data of 21 specimens of E. hlarinae from 

 over its range (AM's from 20 specimens, S's from 7) : 



AW 54-63, mean 57.5; PW 74-93, mean 80.2; AP 14-21, mean 17.7; 

 SB 26-36, mean 29.6; ASB 21-28, mean 24.1; PSB 7-11, mean 8.4; 

 AL 32-47, mean 40.4; AM 35-45, mean 40.6; PL 63-82, mean 70.2; 

 S 35-39, mean 37.7. Width of head of sensiila of seven specimens, 

 9-11, mean 10. 



Eyes: Two pairs; anterior pair lateral to posterolateral setae. 

 Diameter of anterior eyes of eight specimens, 7 to 12, mean 9.4 ; 

 of posterior eyes, 7 to 10, mean 8.5. 



Dorsal setae: Similar to the scutal setae, with large setules 

 spaced over the shaft; spiny appearance. In unengorged speci- 

 mens humeral setae lie in first "posthumeral" row. Length of 

 humerals of 16 specimens, 57 to 67 ; of setae near the middle of 

 the first posthumeral row, 44 to 60 ; of setae in the posterior group, 

 35 to 47.
