setas in the central whorl are a little shorter^ and that even 

 some setse belonging to a fourth whorl are present on the 

 lower side of a comparatively long distal part of the antenna. 



Scuta. — The second scutum (fig. 1 h) with the posterior 

 margin very flatly convex; the antero-lateral setaa are turned 

 much forward and somewhat longer than the breadth of the 

 proximal autennal joints, A little more posteriorly a lateral 

 seta is insertetl, which is considerably longer than the antero- 

 lateral one, and directed outwards and somewhat forwards. 

 Most of the seta3 along the posterior margin are proportion- 

 ately rather long, and one paii", which are inserted a little 

 farther from the margin, are conspicuously longer than the 

 antero-lateral pair. On the first scutum the antero-lateral 

 pair are not half as long as the lateral pair, which are very 

 long, and a pair inserted at some distance from the posterior 

 margin are only a little shorter than the lateral pair. All 

 following scuta, from the third to the thirteenth, each with 

 at least one pair of lateral long seta3 ; on the third, fifth, 

 eighth, and eleventh scuta a pair of antero-lateral seta) could 

 be observed, but all incomplete or broken off. The penulti- 

 mate scutum (fig. 1 c) a little emarginate in the middle of the 

 hind margin, with two pairs of seta3 slightly shorter than the 

 long lateral pair. 



Legs. — In the adult specimen the last pair of legs (fig. 5 a) 

 are rather long ; the tibia on the dorsal side, with some short 

 seta) and a distal, very thick seta, which is two thirds as long 

 as the depth of the joint; the metatarsus nearly twice as 

 long as deep, with six short sette in the anterior dorsal row ; 

 the tarsus is strongly widened towards the base, three times 

 longer than deep, with eight rather short setie in the anterior 

 dorsal row; the anterior claw (fig. 5 h) is short, with the basal 

 part deep ; the posterior claw is proportionately slender, 

 much curved, and more than two thirds as long as the other; 

 the front seta is very long and robust. The tenth pair (fig. 

 5 c) somewhat shorter, and especially with the two distal 

 joints much more slender than in the twelfth pair, the meta- 

 tarsus being two and a half times, the tarsus more than four
