the outer side. The second whovl begins below on the fifth 

 to seventh joiutSj and above on the seventh or eighth; at the 

 middle of the antennas not only is this whorl complete, but a 

 seta is inserted below between the two whorls, and on the 

 distal joints three seta) are well developed behind each other 

 on the lower margin. The seta) in the central whorls are 

 scarcely of medium length, slightly longer above than below. 

 The oblong terminal joint has (fig. 2 6) a moderately large or 

 large and long-stalked striped organ inserted on a pro- 

 tuberance, a rather small and short-stalked organ with feebly 

 developed stripes, and some styliform, slightly curved sensory 

 setje. 



Scuta. — The second scutum (fig. 2c) with the posterior 

 margin rather deeply emarginate ; the lobes on each side of 

 this emargination are posteriorly angular, thus forming a 

 kind of triangular plate which is several times broader 

 than long; the antero-lateral seta) are directed somewhat 

 forwards and considerably longer than the breadth of the 

 basal antennal joint ; a lateral pair of seta) are directed 

 essentially outwards, and are as long as or longer than the 

 antero-lateral pair ; at each posterior angle a rather long- 

 seta is inserted. The scuta, the last one excepted, posteriorly 

 emarginate, and with two angles essentially as iu the second 

 scutum; the fi.rst, fifth, eighth, eleventh, and thirteenth 

 scuta each with an antero-lateral and a lateral pair of setee 

 (on the thirteenth scutum [fig. 2 rf] these are lateral and 

 postero-lateral) partly somewhat longer and partly somewhat 

 shorter than the corres])onding two long pairs on the second 

 scutum, and all directed at least much outwards (with 

 exception of the posterior pair on the penultimate scutum); 

 the third, fourth, sixth, seventh, ninth, tenth, and twelfth 

 scuta each with one pair of long or very long protruding 

 seta); all scuta with a pair of rather long or long seta' 

 inserted at the ])osterior angles and directed upwards, and 

 these last setie are ])resent even on the last scutum on each 

 side of a median shallow depression. 



Legs. — The posterior pairs present considerable variation
