iiu'i.sur iirr M)iuo\vhat diftViviit Iroiii tluise of the I't'iuuk' (seo the liguros). No Murfaco pores 

 are visible. In other respects like that of the female. 



First antenna: - Tliis is slightly lunger relatively than that of the i'einalc. 

 Bristles of the seventh joint: The b-bristic is alxmt as long as the anterior side of the second 

 and the third joints; it has five filaments, of which the three proximal ones have suctorial organs. 

 The proximal one of the three latter have distally of the sucker only an indication of a verruciform 

 swelling. The two others, which are long and powerful, the distal one of them extending some 

 distance beyond the point of the bristle, are fui-nished with from ten to thirteen small suctorial 

 organs distally, proximallv of which there is a small verruca. Distally of the three filaments 

 just mentioned there are on this bristle two short, bare filaments. The c-bristle is somewhat 

 longer than the preceding one, attaining about the same length as the anterior sides of the second 

 to the fourth joints. It has ten filaments, of which the three proximal ones have suctorial 

 organs; these three filaments are of quite the same types as the corresponding filaments on the 

 b-bristle; on the two distal ones of them ten or eleven suctorial organs were observed. The 

 seven distal filaments of this bristle are bare or almost so. Bristles of the end joint: The f- and 

 g-bristles are subequal, not quite as long as the shell (length of the shell : length of these bristles — 

 about 11 : 9); the former has eleven, the latter twelve, filaments, each furnished with from 

 none to four weak secondarv spines. In other respects this limb agrees entirely with that of 

 the female. 



Second antenna: — This is slightly stronger than that of the female. E n d o- 

 p o d i t e (fig. 12) : On the first joint this has, besides the group of four proximal bristles, a single 

 distal bristle as well, of about the same length as the longest bristle in the proximal group. 

 With regard to this character compare the description of the female given above. In other 

 respects this antenna is quite like that of the female. 



Mandible: — This is very like that of the female. The second end o p o d i t e 

 joint has on the anterior side nine or ten more or less long bristles with short hairs and thirteen 

 or fourteen cleaning bristles with varying arrangement. The two postero-distal bristles on 

 this joint are almost equally strong, agreeing completely with those of the female; fig. 5. 



The maxilla and the fifth limb are like those of the female. 



Sixth limb: — This is very like that of the female, but the bristles are, however, 

 furnished with softer hairs almost throughout. The numbers of bristles observed were as follows: 

 Protopodite: First endite: two or three distal bristles and two medial bristles. The 

 second endite: two distal bristles and three medial ones. The third endite: four distal bristles 

 and one medial bristle. The epipodial appendage is represented by three or four 

 short bristles. Exopodite: The endite on the'first joint has six distal bristles and one 

 medial bristle; the second joint has 17 or 18 bristles; fig. 11. 



Seventh limb: — This is very like that of the female. The number of bristles 

 observed was as follows: seven ventral and from five to seven dorsal ones concentrated distally; 

 eight or nine ventral and nine or ten dorsal ones scattered proximally of these. 



Penis (fig. 15): — Of the type characteristic for this sub-family; for details the reader 

 is referred to the accompanying figure.
