required to determine the exact relationship between E. carolinen- 

 sis and E. ohioensis. 



22. Euschongastia crateris, new species 



Figure 7,c; Plates 5, 8, 19 



Description : Size : Length, 275 to 800 ; width, 195 to 800. 



Shape: Ovoid; broad oval; almost square. 



Color: Yellowish, when dissicated. 



Gnathosoma: Seta on palpal femur large and strong with 

 numerous long, slender setules. Seta on palpal genu smaller, with 

 many long, slender setules. Dorsal seta on palpal tibia slender 

 with a few slender setules ; lateral seta usually nude, occasionally 

 with one or two small setules; ventral seta with long slender 

 setules. Palpal claw with four or five prongs, three longer with 

 the median prong longest and one or two shorter on the outer 

 curvature. Long spur on palpal tarsus. Galeal seta heavy, curved, 

 with rather long curved setules arising on opposite edges. Cheli- 

 ceral base heavy; blade with a rather large dorsal tooth and a 

 large ventral tooth. Punctae on palpal coxa and cheliceral base. 



Legs: Leg I with two slender genualae and a microgenuala, 

 two tibialae and a microtibiala, a spur of moderate size with a 

 microspur about half the length of the spur distal and posterior, 

 a slender subterminala and a small parasubterminala, and a pre- 

 tarsala. Leg II with a slender genuala, two tibialae, a moderate 

 spur with a microspur proximal or anterior to it, and a pretarsala. 

 Leg III with a genuala. Nonspecialized setae similar in form and 

 distribution to those of E. caroline^isis. Empodium slightly longer 

 than claws. Leg segments strong; legs without noticeable taper. 

 All segments with punctae. 



Anomalies : One specimen with three genualae I. One specimen 

 with a tibiala III. 



Scutum : General form much like that of E. blarinae. Punctae 

 scattered. Pits near the posterolateral ends of the ridges usually 

 distinct, Scutal setae with heavy shafts closely covered with long, 

 slender setules. Sensillae broad clavate; heads frequently some- 

 what pyriform, clearly distinct from pedicels.
