any ventral spine; spiracles large and distinct. 
(Newportia sens. str.). 
b. First dorsal plate with a simple, semicircular or nearly 
semicircular transverse cervical sulcus; its paired longi-

depression caudad of median sulcus. 
ce. Prefemur of anal legs on dorsomesal surface with two 
rows of from seven to ten spinules. 
N. longitarsis (Newport).

_ N. longitarsis sylvae, subsp. nov. 
bb. First dorsal plate with the transverse cervical sulcus bent

pression caudad of its apex; paired longitudinal sulci bi- 
furcating cephalad, the inner branches meeting in the 
depression and the lateral extending cephalo-ectad to the 
transverse sulcus, the branches together forming a more or 
less w-shaped outline. 
ce. First joint of tarsus of anal legs clavately thickened 
distad and with corner drawn out at side into a pointed 
angle; part of first plate in front of transverse sulcus 
about as long as that caudad of it. 
N. collaris Kraepelin. 
ec. First joint of tarsus of anal legs not thus clavately thick-
