 of S triarticulate. Basal joints cylindrical, superficially somewhat creased, usually bent more 

 or less downward. At the juncture of the basal and middle joints is a ventro-laterally directed, 

 slightly curved smooth process wliich is heavily chitinized. Middle joint of 2nd antennae of

S witii a sigmoid flexure; close to its basal end on tlie dorsal surface are 3 slender fleshy 

 processes, the innermost one always larger, the other two may nearly equal it, or may be con-, 

 siderably smaller. All 3 are similar in shape, tapering, curved downwards, pointed, and with 

 the lower surface provided with a row of small papillae. On the dorsal surface of this same 

 middle joint is a row of a1)out 10 slender processes, the middle ones usually being shorter. 

 The whole of the middle segment of the 2nd antennae of the male gives the appearance of 

 being superficially annulated. The hand, as seen from the outer side, is well shown in 

 Figure 7. It will be observed that: the distance from the thumb notch to the tip of the
