light line along each side of the dorsum, this anteriorly in part break- 

 ing up into spots suggesting the arrangement in N. fijiana; these lines 

 and the ventral surface and lower part of sides ferruginous. Anal 

 segment light excepting the caudal portion of the tergite and the entire 

 ventral scale which are black. Legs in part dusky over a fulvous 

 background. The antennae similar, being thus obviously lighter 

 than in A^. fijiana and lincata. 



The antennae are most nearly like those of A", lincata, the fifth 

 joint, c. g., being similarly short with strongly constricted base, above 

 which the article expands abruptly'. 



A conspicuous characteristic of this species is in the rather finely 

 and evenly but strongly roughened metazonites, especially dorsally, 

 the coarser, low tuberculation or granulation here contrasting with 

 the much finer grained even surface of the prozonites. Hairs numer- 

 ous, short and straight. 



Number of segments, fifty. 



Length (female), 13 or 14 mm.

Type.— M. C. Z. 4,955. Paratypes.— M. C. Z. 4,956. Solo- 

 mons: Wainoni Bay (W. M. Mann). 



Resembling A'^. fijiana; but, aside from being an obviously more 

 robust species, it differs in wholly lacking any series of light spots above 

 and in showing a distinct annulation of the somites, the border of 

 metazonite and the underlying part of prozonite being commonly 

 light in contrast with the blackish remaining portion. Legs fulvous. 

 Antennae dark. 



Eyes subrhomboidal ; ocelli in four or five oblique series, c. g., 3, 4, 4, 

 4, 3. Fifth article of antennae strongly constricted at base, the sixth 

 cylindrical. A sulcus across caudal portion of vertex, short but dis- 

 tinct. 



Collum equalling or extending a little below lower edge of second 

 tergite. 



Segments constricted as usual, with metazonites higher than pro- 

 zonites, but constriction not so sharp or deep as in A", fijiana. Striae 

 rising part way up the side on a few anterior segments but on most 

 confined to ventral surface and few though distinct, these crossing 

 metazonite and cur^'ing dorsad on caudal edge of constriction but not 

 crossing prozonite. Setae much shorter than in A^. fijiana.
