THE GENERA AND SPKCIES OF SYMPIIYLA. 71 



from tlio base, ratlier short on the proximal and very short on 

 the most distal joints; in the distal half of the antennae two 

 or three minute setas (fig. 2 a) are found on the lower side 

 behind each central whorl, and only on tlie subapical joint a 

 single seta of this rudimentary secondary whorl has been 

 developed on the upper side. 



Scuta. — The second scutum (Hg. 2 h) with the posterior 

 margin between the processes feebly curved and without any 

 striped band ; the processes are narrow and distaliy pro- 

 duced, considerably longer than broad ; a single short seta is 

 found on each side slightly iu front of each process which 

 has no seta) along the lateral margins, while the subapical 

 seta is inserted rather near the end. The distance between 

 the processes is one half longer than their length. Each 

 lateral margin of the scutum with four seise in all, of which 

 the antero-lateral one is about half as long as the processes 

 and the other short. The third scutum (fig. 2 b) rather 

 similar to the second: the processes are somewhat longer 

 than broad, the three seta) in front of their base and near the 

 end as in the preceding scutum, the basal distance between 

 the processes twice as long as their length; each lateral 

 margin with two seta3 in all, one of which is near the process, 

 and the other, the antero-lateral one, is a little shorter than 

 that on the second scutum. 



Legs. — The last pair (fig. 2 c) is rather robust. Tibia and 

 metatarsus each with a distal dorsal protruding seta, which is 

 somewhat shorter than the depth of the last-named joint. The 

 tarsus is a little more than three times longer than deep, with 

 a dorsal protruding seta, a little longer than the depth of 

 the joint, inserted at the middle, and with this in the anterior 

 row only a single subapical seta which is somewhat shorter 

 than the other. The claws (fig. 2 d) are ratlier slender, the 

 posterior one nearly as long as the other; the front seta is 

 short. The first pair (fig. 2 e) about half as long as the 

 second and somewhat longer than the tarsus of the last pair. 

 The femur is about as long as deep, the tibia a little longer 

 than deep and as long as the tarsus, which is nearly twice as
