2IO ENTOMOLOGISK TIDSKRIFT 190I. 



— The joints which have their basal part not hidden by a whorl 

 of glabrous set?e from the preceding one, exliibit another shape 

 of their basal part. This other structure is thus found in the 

 fifth, seventh, ninth, eleventh and twelfth joints (in the last joint 

 the feature is indistinct): the proximal part of these joints is 

 shaped like an hour-glass (pi. 2, fig. i c, i d and i e), but it is scar- 

 cely marked off by a transverse line from the distal part; in 

 contracted specimens this curious proximal part is retracted 

 deeply into the preceding joint (fig. i d), and much deeper than 

 we find is the case in the other joints; in extended specimens 

 (fig. I f) it is scarcely retracted. — The structure of the flagel- 

 lum is thus very complicated; the figures on pi. 2 exhibit suf- 

 ficiently the length of the setre, the plumose clothing etc. 



The lîagellum in K. Wheeler 2 is similar to that in K. 

 niirahilis in most respects. I have examined two complete 

 flagella, and each contained fifteen joints (pi. 2, fig. 2 k); of 

 ten specimens examined by Wheeler eight had fifteen, one spe- 

 cimen had fourteen and one only eleven joints in the flagellum 

 (Wheeler op. cit. p. 844), but unfortunately he does not say 

 if the last-named specimen was adult or immature or showed signs 

 of anomaly. My figure shows that the flagellum has the same 

 joints furnished with a whorl of glabrous setîe as we saw in K. 

 niirahilis, the division into subjoints is also as in that species. 

 But all the joints (the apical one excepted), which do not pos- 

 sess strong subapical setae, have a whorl of very short hairs close 

 to their end. The apical joint (pi. 2, fig. 2 1) has two whorls 

 of long pubescent setag as in K. inirabilis, and in the subapical 

 one seven setae are present in both specimens. The basal sub- 

 joint of the first joint has four short setaî, the two upper of 

 which only half as long as the two others. 



I have examined a complete flagellum of A'. cJiilensis (pi.. 

 3, fig. 2 g, 2 h and 2 i). It contains thirteen joints and does 

 not differ very much in structure from that in K. mirabilis, but 

 it is much more slender and the joints are more elongated. At 

 least the first joint and probably even all the other joints are 

 still more slender than shown in my figure (2 g), since the joints 

 appeared to be somewhat flattened by the pressure of the glass- 

 cover in the preparation lent me by Dr, Silvestri. 'I'he sub-
