150 NATHAN BANKS. 



Two acute spines near end of dorsal shield oriiata. 



Two rounded tubercles instead of spines Kayii. 



Neither spines nor tubercles biinaculata. 



Cynorta ornata Say. 



This species is found in the southeastern part of the United States, 

 usually under rotten logs. The young are lighter colored, and with 

 long, slender palpi. 



Cyiiorta Sayii Simon. 



This was described as ornata Say by Wood, but is plainly a differ- 

 ent species. It is usually without the white lines on the dorsum that 

 are so common in ornata. It ranges somewhat more northward than 

 that species, extending up to Kansas. It is found under and among 

 dead leaves. 



Cynorta bimaciilata n. sp. Length 4 mm.; width 2.9 mm.; femur IV 

 2.5 mm. — Color: dorsum brownish red, with two long, somewhat lunate white 

 spots near the end of the dorsal shield ; venter red. Legs yellowish, marked 

 with fuscous toward their tips. Body finely granulate, without large tubercles 

 or spines ; hind margins of the posterior segments furnished with a row of small 

 tubercles. Legs 4-2-3-1 ; femora III and IV curved ; patellae and tibia? Ill and 

 IV roughened. 



A smaller species with shorter legs than the other two. San Diego, 

 Cal. ; given me by Dr. Geo. Marx. 



The Phalangodidse are represented by four genera : 



But one compound claw to each of the four posterior tarsi ; palpi not as long as 



the body Sclerobiiiins. 



Two simple claws to each posterior tarsus. 

 Eye-tubercle pointed, arising from the anterior margin ; palpi shorter than the 



body Sifalces. 



Eye-tubercle arising from the middle of the cephalothorax ; palpi as long as 

 body. 

 Second joint of palpi more than three times as long as wide ; legs very long. 



Phalangodes. 

 Second joint of palpi about twice as long as wide; legs much shorter. 



Scotolemon. 

 Phalaiigodes Tellk. 

 Acanthocheir Lucas. 

 Phrixis Cope. 

 This differs from Scotoleynon in having much longer legs and more 

 slender palpi. We have two species : 



Eyes none, no spines on body ; cave form armata. 



Eyes present, spines on body, non-cavernicolus spiiiifera. 



Phalaiigofles armata Tellk. 

 Phrixis longipes Cope. 



Mammoth Cave, Kentucky.
