868 Mr. Hugh Scott on certain Nyderihiid^, 



apex sharp and not dark, with no marked curve in the horizontal 

 plane, and with bristles (growing shorter towards apes) extending 

 from base almost to extreme apex. 



Abdomen op 9- (Figs- 17 and 18.) — Basal tergite small, bear- 

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

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

 margin set with long bristles. Line of division between tergites 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 chitinoiis plate (Fig. 176) 

 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 equal to its length ; the segment tapers soniewhat, but has its 

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

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



Basal sternite as in the (J . 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 pieces (Fig. 18o) separated by a small interval at the 

 middle line: hind margins of these pieces bearing long bristles; 

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

 Anal segment ventrally showing 2 jiairs 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 shortness of the anal segment in the $, this 

 species resembles N. sti/lidioj^sis, Speiser ; * but the $ anal 

 segment of A^. smderi is dorsally even shorter than that 

 of N. stylicliopsis. The $ $ of the two species differ in the 

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

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

 N. sautcri has the legs only moderately broad.
