second protopodite joint and the second endopodite joint there are groups of short, fine hairs, 

 and dorso-distally on the first endopodite joint there are also a few short hairs. 



Maxilla: — Protopodite (fig. 11): The first endite is furnished with seven 

 powerful bristles of moderate length. Of these the two inner ones are subequal and furnished 

 with a few oblique wreaths of long, stiff secondary bristles ; the distal one of these wreaths continues 

 rio-ht to the point of the bristles. The other five are subequal and somewhat shorter than the 

 two inner ones; of these five the two outer ones are furnished with rather numerous long, stiff 

 secondary bristles and are trifiircated distally; the other three, one of which is very powerful, 

 are furnished with rather few long, stiff secondary bristles, distally of which there are some 

 short secondary teeth, and have a simple point. The second endite has five rather strong 

 subequal bristles. Of these the inner one has short and exceedingly fine hairs or is bare, one 

 is only rather weakly pectinated distally and the three others have at the middle a few long stiff, 

 secondary bristles and are pectinated distally; on the one next to the outer one the pectination 

 is rather strong, on the two others it is rather weak. The third endite has also five rather powerfid 

 distal bristles, all of about the same length except the inner one, which is rather short and weak. 

 The last-mentioned bristle has short and exceedingly fine hairs or is bare; of the other four, 

 all of which have a few stiff, secondary bristles at the middle, the inner one is bare distally, 

 the others are rather weakly or very weakly pectinated distally. The dorso-distal bristle on 

 the coxale is about as long as the outer bristle on the tliird endite. Of the two bristles on the 

 boundary between the basale and the first endopodite joint the one that is situated near the 

 exopodite is about a tliird of the length of the bristles of the exopodite, the other is still shorter; 

 both are bare. Of the three bristles of the exopodite the distal one is bare, the two others 

 are plumous; all of them are of about the same length as this branch. Endopodite: First joint 

 (fig. 12): Distally on the anterior edge there is a single rather long, plumous bristle. Distally 

 on the posterior edge there are two bristles, one of which is long and powerful, furnished at the 

 middle with rather weak secondary teeth and characterized especially by being bent at almost 

 a right angle somewhat distally of half its length, the other is considerably shorter and weaker 

 and has short, fine hairs. Proximally of these two bristles the edge of the joint is characterized 

 by a strongly projecting, distally bifurcated verruca. The end joint is rather strongly chitinized 

 and has only eleven bristles: three bare a-bristles of moderate length and strength; three 

 b-bristles, of which the anterior one is moderately long, rather strong, furnished at the middle 

 with a few weak secondary teeth and plumous distally, the two others are naked, weak and short, 

 their lengths being somewhat unlike, the shorter one not quite half as long as the anterior one; 

 two c-bristles of the same type and sizes as the short b-bristles, the anterior one being the shorter, 

 and three d-bristles, subequal, very powerful, especially the two anterior ones, the posterior 

 one rather strongly pectinated, the two anterior ones furnished at the middle with rather few 

 fairly strong secondary teeth. Pilosity: Tlie first endopodite joint has transverse series of 

 short, fine hairs. 



Fifth limb: — Protopodite: The first endite (fig. 15, 6" = ?) i« furnished 

 with only five bristles. Of these bristles no. 1, counting from the anterior side of the limb, 

 is very small, furnished m most cases with long, stiff secondary bristles. The others are of mode-
