THE GENERA AND SPKOIES OF SYMPHYLA. 73 



on the distal joints. A second whorl begins below about at 

 the middle of the antenuee, and nearly on the distal third of 

 the appendages a seta is found near the upper margin^ but 

 the whorl is not complete on the outer side of any of the 

 joints. 



Scuta. — The second scutum (fig. 3 h) with the hind margin 

 between the processes nearly straight and without any striped 

 band; the processes are narrow and distally exceedingly 

 produced^ nearly one half longer than broad^ with two setas 

 at the basal part of the outer margin, one subbasal seta at 

 the inner margin, and the usual distal seta inserted very far 

 from the end. The distance between the processes slightly 

 shorter than their length, pjach lateral margin of the scutum 

 with about seven setae in all; the antero-lateral one is several 

 times shorter than the processes, and the other setae are 

 short. The third scutum with the processes somewhat 

 shorter, a little longer than broad, the distance between 

 them somewhat longer than their length, six seta3 in all 

 (the distal one as usual not included) along each lateral mar- 

 gin, otherwise essentially as the second scutum. 



Legs. — The last pair, which is similar to the penultimate 

 pair (fig. 3 c), is moderately robust. The tibia with a distal 

 dorsal seta about half as long as the depth of the joint; 

 metatarsus with two similar setae in the anterior dorsal row. 

 The tarsus a little more than three times longer than thick ; 

 in the anterior row three protruding setas as long as or 

 slightly longer than the depth of the joint. The anterior 

 claw (fig. 3 d) moderately short and robust, a little longer 

 than the other ; the front seta is short. The first pair (fig. 

 3 e) not one third as long as the second, and somewhat 

 shorter than the tarsus of the last pair of legs; femur and 

 tibia shorter than deep, the tarsus somewhat longer than 

 thick (fig. 3/) ; the claws are well developed, much curved, 

 and subequal in length. 



Cerci (fig. 3 g). — They are even longer than the last pair 

 of legs, very robust, and nearly four times longer than deep, 

 decreasing much in depth in the distal third. They aie
