of the individuals, as may be observed in the table given below. In one 

 specimen, measuring 3"75 mm. long, the left antenna consists of 29 joints 

 while the right antenna has but 27 joints. 



The setse placed on the inner side of the antennal joints are not longer 

 than those disposed on the outer aspect. The first six joints have only 

 three principal setae visible from above, but on the 7th joint, or thereabouts, 

 a secondary whorl of setse commences. A whorl of two or three very short 

 setse takes its origin (on the dorsal side) from about the 8th joint, and is 

 placed in front of the principal or central whorl. The terminal joint is 

 provided with numerous long and prominent setse and, arising from a median 

 protuberance at its apex, is a large stalked (sense ?) organ. Placed near 

 the base of the latter is a smaller organ of similar type but with a shorter 

 stalk. A rudimentary organ (r.o. in fig. 3) of very small size is present on 



each joint, from the third joint onwards^ and is placed to the oatside of the 

 median dorsal line but situated within the anterior whorl of very short setse 

 mentioned above. 



Scuta (figs. 1 and 2). — The first scutum with the posterior margin more 

 convex than that of the second and the succeeding scuta. The second scutum 

 with its antero-lateral setse very much longer than the lateral setse but little 

 more than the breadth of the proximal antennal joint. Two pairs of its lateral 

 setse but little more than half the length of the antero-lateral setse^ only 

 slightly longer than the remaining setse^ and inclined outwards and back- 

 wards. The thirteenth (penultimate) scutum is prominently emarginate 

 posteriorly and with lobes broadly rounded. 



Legs (figs. 6, 7, 8, and 9). — The first pair of legs with an elongate, slender, 

 and slightly curved anterior claw. The smaller claw somewhat more 

 strongly curved and reaching to about half the length of the former. The
