Description. 



It is about one inch in length of body: some southern individuals 

 have measured one inch and a fourth. Its 

 breadth at the widest part is about one- 

 sixth of an inch. Its general color is a 

 light olive-brown. The head is large, 

 broader than the contiguous rings of the 

 body, of an oval flattened outline, and is 

 marked with two converging black lines on 

 its front. The antennae are quite long, 

 many-jointed, attenuated, being thread-like 

 at the end. The eyes are black, large, 

 prominent, and compound; beneath them is 

 a pair of spined palpi; and back of these, 

 on the hinder part of the head, a pair of 

 leg-like pointed jaws, ending in a black 

 tip. The head and its appendages are shown 

 in enlargement in Figure 53, in which an 

 excellent representation of the creature is 

 given. 



The body has its sides nearly parallel, 

 being but a little broader at its middle. It 

 is traversed centrally upon the back by a 

 sharply defined black line which com- 

 mences on the head between the eyes and

terminates at the last abdominal joint. Upon (After Wood.) 



each side of this is a similar well-defined black line, commencing at the 

 eyes and continuing over the entire body. The upper side of the 

 body shows eight plates or shields, which are suboval in general out- 

 line, sharply excavated posteriorly, and thin and reflexed at the sides : 

 under a magnifier these show granulations or spines. Underneath, 

 the body shows fifteen rings, two of which are covered by each of the 

 dorsal shields except the last. 



There are fifteen pairs of long legs, armed with several toothed 

 ribs, and with spines at the end of the joints. The two principal 

 joints (tibia and tarsus) have each two incomplete black bands. The 

 ends of the legs (metatarsal joints) are many-jointed, long, round and 

 terminated in a short, black, acute hook. The front legs are about 

 two-thirds the length of the body. The following ones increase in 

 length to the terminal pair — the latter, longer than the body (in the 

 male one-fourth longer, in the female twice as long).
