THE GENERA AND SPECIES OF SYMi'HYLA. 89 



12. Scolopeudrella antennata, u. sp. PL 1, figs. 

 6 a — 6 i'. 



Material. — Eleven specimens from five localities, and 

 several of them with the full number of legs. 



Head. — Very moderately elongate, only rather little 

 longer than broad. The central rod is not interrupted; its 

 most anterior part and the frontal branches are thin ; a 

 strong median rod exists apparently between the posterior 

 branches. 



Antennas. — In the adult specimens the number of joints 

 varies from twenty-three to twenty-nine. The setas in the 

 central whorls, with exception of those on the inner side of the 

 proximal joints, are very thick at the base, nearly obliquely 

 conical, moderately short on the proximal and short on the 

 distal joints, and all set with a number of fine hairs (fig. ^a). 

 On the inner side from the base to the fourth or to the eighth 

 proximal joint the seta; of the central whorl are naked, very 

 thin (fig. 6 h), and much longer than the thick pubescent 

 seta3 ; on the following joints these thin and naked seta) be- 

 come gradually much shorter and situated behind the central 

 whorl (fig. 6 c), which on all sides contains only thick and 

 pubescent setas. The secondary whorl begins below about 

 on the eighth joint with one short, thick, and pubescent 

 seta ; on the distal joints two or three such set« are present 

 below, but on the upper part of the joints the whorl is 

 completely absent on all joints. The terminal joint with a 

 number of very short, thick, and pubescent setae. 



Scuta. — The second scutum (fig. 6^) without striped 

 band on the hind margin. The processes are large, a little 

 broader than long, distally somewhat produced, with the 

 apex narrow ; they have two setas at each margin, and the 

 distal seta is somewhat removed from the end. The distance 

 between the processes about as long as their length. The 

 antero-lateral sette are slightly longer than the processes ; 

 two pairs of the lateral seta3 are rather long, and the other 

 marginal setae of middle length. The third scutum (fig. 6 (i)
