joints. The seta) in the ceutcal whorl are all naketl^ slender 

 and tapering from the base, modei'ately long on the jjroxinial 

 joints, but not half as long on the most distal joints. About 

 at the end of the basal third of the antennae the secondary 

 whorl begins below (fig. 4 a) ; on the distal half of the antennas 

 it is also developed on the upper side, and at least on the most 

 distal joints a seta of a third whorl protrudes from the lower 

 margin. All the joints, with exception of a few proximal 

 ones, with a number of clear, circular small spots on the 

 outer side (fig. 4ft); in these spots a minute seta seems 

 always to be inserted, but it is often so short that it is exceed- 

 ingly difficult to discover. 



►Scuta. — The second scutum (fig. 4 h) with the hind margin 

 between the processes nearly straight, and without striped 

 band. The processes are rather large, nearly regularly tri- 

 angular, scarcely broader than long, with about four seta) 

 along each margin and the usual distal seta near the end. 

 The distance between the processes is much shorter than 

 their length. The antero-lateral setiD are about of middle 

 length, at least somewhat shorter than processes; among the 

 other moderately numerous lateral seta3 two pairs are of 

 moderate length. The third scutum (fig. 4 h) has the pro- 

 cesses somewhat shorter than broad, but they are only half 

 as long as the distance between them, with about three seta? 

 along each margin ; the antero-lateral setie as those on the 

 second scutum. 



Legs. — The last pair (fig. 4 c) are proportionately rather 

 long. The tibia with two dorsal protruding set^e slightly 

 more than half as long as the depth of the joint ; the meta- 

 tarsus with three rather similar setae in the anterior dorsal 

 row, all somewhat or considerably shorter than the depth 

 of the joint. The tarsus rather long, four and a half times 

 longer than deep, generally with five, and at least with four 

 protruding seta) in the anterior dorsal row, and the setiu at 

 most a little longer than the depth of the joint. The anterior 

 claw (fig. 4 rf) is rather long, moderately robust and curved, 

 somewhat longer and thicker than the other ; the front seta of
