HANSEN: ON SIX SPECIES OF KOENENIA. 223, 



Besides on the fixed finger two rudimentary spines and on the 

 movable finger a sharp angle instead of a spine. 



Palpi (fig. 2d). They are rather slender. The tibia is 

 nearly three times longer than thick. The second metatarsal 

 joint is a little longer than the first and not twice as long as 

 thick. The first tarsal joint is considerably shorter than the se- 

 cond, and the third joint is about as long as the first and the 

 second together. 



Legs. Rather slender. The first pair (fig. 2 e) has the 

 tibia not three times longer than thick; the third metatarsal- 

 joint is much longer than the fourth, with its stift" seta (s) in- 

 serted close to the apex; the last tarsal joint is a little more 

 than four times longer than thick. — The last pair of legs (fig. 

 2 g) has the metatarsus (m) as long as both tarsal joints (ta) to- 

 gether, its sensory seta is inserted towards the middle of the 

 joint and reaches a little beyond its end; the last tarsal joint is- 

 almost twice as long as the first. 



Abdomen (fig. 2 i and 2 h). Ventral sacs (p) are well 

 developed on the fourth, fifth and sixth segments; the distance 

 between the sacs of the same pair is in the fourth and fifth seg- 

 ments about twice as long as the slit, in the sixth segment some 

 what shorter. On the fourth and the fifth segments are inserted 

 three pairs of long, robust, plumose set^e between each pair of 

 sacs and a little in advance of them; the three hairs on the 

 same side of the median line are arranged in a transverve row,, 

 but rather close to each other, while the distance between the 

 two hairs of the pair next to the median line is somewhat lon- 

 ger, but yet rather short. In front of each sac and close to 

 it we find in all three segments four somewhat shorter and more 

 slender hairs and between these and the naked side of the ab- 

 domen still two shorter hairs. Thus the ventral side of the fourth 

 and the fifth segments possesses nine pairs of hairs (and setae),, 

 on the sixth segment only six pairs, the three long pairs between 

 the sacs being absent. — The three posterior segments (fig. 2 i) 

 have a seta in the median line; the last segment has nine setae. 



Flagellum (fig. 2 k and 2 1). It contains normally fifteen 

 joints (on the number found by Wheeler see above p. 210) and. 

 is moderately robust. Its first joint, without the basal subjoint,
