CHIGGERS — FARRELL 205 



or anterior to it, and a pretarsala. Leg III with a genuala. Non- 

 specialized setae beyond trochanter of leg I mostly with numerous, 

 fine, short, curving setules; those on dorsal surface of the tarsus 

 with fewer, straight setules. Nonspecialized setae of leg II with 

 numerous, curved setules on the posterior and ventral surfaces 

 and fewer, straighter setules on the anterior and dorsal surfaces. 

 Most nonspecialized setae on leg III with few, straight setules; 

 those on the dorsal surface generally with curved setules. Empod- 

 ium slender, slightly longer than claws. All coxae with small 

 punctae. Punctae apparently lacking on distal leg segments 

 usually; but a few specimens with very fine punctae on clear, 

 flattened segments. 



Scutum : Generally similar in form to that of E. blarinae, with 

 a tendency to be v/ider in engorged specimens. Ridges frequently 

 obscured. Two pits usually present near the posterolateral end of 

 each ridge. Without apparent punctae. Setae similar to those of 

 E. blarinae, but less heavy and with less heavy setules. Sensillae 

 clavate; pedicel long and slender; head ovoid, well covered with 

 setules on the anterior surface, sparsely covered on the posterior 

 surface.
