Audomk.n of 9- (^'^n^- 17 and 18.) — Basal tergite small, bear- 

 ing short bristles on its surface, with no long bristles on it,s hind 

 margin. Tergite 2 (Fig. 17a) short, its surfiice bare, its hind 

 margin set with long bristles. Line of division between tergitcs 1 

 and 2 not very definite in all aspects. Beyond tergite 2 an area of 

 soft skin bearing rather short bristles, not close, and some long ones 

 posteriorly. This area terminates in a chitinous plate (Fig. 17//) 

 nearly twice as broad as long, bare on its surface ; its hind margin 

 bears 4 very long bristles set apart, and between each 2 of them 

 are 2 or 3 short dark spines. Anal segments short, its basal breadth 

 quite eijual to its length ; the segment tapers somewhat, but has its 

 apical breadth = more than \ its basal breadth ; surface almost 

 bare, a few moderately long bristles at the hind comers. 



Basal sternite as in the (^ . Sternite 2 with about 2 irregular 

 rows of .short bristles on its surface, its hind margin bearing long 

 bristles. Sternites 3, 4 each bearing a pair of slightly elevated 

 chitinous ]ne{'es (Fig. 18(f) separated by a small interval at the 

 middle lino : hind margins of these ])ieces bearing long bristles ; 

 and those of sternite 3 also bearing short bristles on the surface. 

 A7ial segment ventrally showing 2 ]>airs of blunt rounded lateral 

 elevations, which bear moderately long bristles : also some .short 

 bristles on the surface of the segment near its base, and some 

 moderately long ones at its hind border. 



In the shortn(>ss of the anal segment in the ^, this 

 species resembles N. stj// id i apsis, Speiser ; * but the $ anal 

 segment of N. savtcri is dorsally even shorter than that 

 of i\^. sti/Iidiojms. The $ $ of the two species ditJ'cr in the 

 form of the anal segment and in other respects. N. 

 stylidi(ypsis also has the thorax longer than broad; and 

 N. sauteri has the legs only moderately broad.
