NOTASriS SERRATA. 367 



the extreme length and roughness of the hairs on the 

 notogaster, and by being usually covered with frag- 

 ments of lichen, &c., and by what looks like a confer- 

 void growth. 



Colour dull, darkish brown. 



Texture coarsely pitted with circular or subcircular 

 areolations, entirely without polish. The whole crea- 

 ture covered with short villous processes. 



Form pyriform ; posterior margin very round. 



Cephalothorax. — Rostrum narrow but rath er rounded ; 

 rostral hairs curved and pectinated. Cephalothorax 

 long, thick (from sternal to dorsal surfaces) ; the pos- 

 terior part narrow dorsally, but wider below ; decidedly 

 constricted before joining the progaster. No lamellse 

 or translamella ; the lamellar hairs, however, persist 

 (on the dorso-vertex) and are curved inward and ser- 

 rated. Pseudo-stigmata near together, very dorsal, 

 strongly projecting. Pseudo-stigmatic organs of 

 medium length, with fine peduncles and short pyriform 

 or almost globular heads. Interlamellar hairs long, 

 flexible, pectinated. First tectopedium small and round, 

 second and third conspicuous. No opisthophragmatic 

 processes. Apodemata reaching the sternum. 



Legs moderately long; femora large and rounded, 

 the two front pairs with thin proximal ends, w^hich, 

 however, are short. Tarsi almost elliptical, but with 

 long peduncles bearing the claws, which are tridactyle. 

 Tactile hairs small. There are the following curved, 

 pectinated hairs on the legs, viz. a whorl of three or four 

 on each of the three central joints of each leg of the 

 first or second pairs ; one hair on each coxa and tibia, 

 and a whorl on each femur and genual of the third and 

 fourth pairs. All the tarsi are clothed with stout, 

 setiform hairs. 



Abdomen oval. Notogaster coarsely pitted; very 

 narrow at the progaster, and there the notogastral plate 

 does not cover any part of the side of the abdomen, but 

 broad posteriorly, and there turned under so as to form 

 the whole posterior, and part of the ventral skeleton.
