124 On new Lepidoptera from the Solomon Islands. 



across the middle of the cell ; a stripe across external third 

 blackish and transverse from costa to third median, where it 

 bends outwards at right angles, becoming grey with an orange 

 border, then again bent at right angles to below second 

 median branch, again inwards to a point halfway between its 

 commencement and the discoidal spot, and then abruptly 

 downwards to just beyond the middle of the inner margin; 

 the line thus forms what is called a key pattern ; outer bor- 

 der greyish, especially on apical half, bounded internally by 

 a blackish interrupted line, less strongly angulated than the 

 discal stripe ; a few dusky points on the fringe towards apex : 

 secondaries with an orange dot in the cell; discal line and 

 border nearly the same as on primaries ; fringe immaculate : 

 head slightly greyish, collar rather reddish. Wings below 

 pearly golden stramineous, with markings as above, but only 

 the grey and black markings strongly defined, the others 

 obsolete: body white; anterior and middle pairs of legs 

 stramineous in front. Expanse of wings 23 millim.

Not unlike Botys polytesalis from the Upper Amazons ; 

 the angulation of the discal line is like that of B. inanitalis 

 (Lederer, Mon. pk ix. fig. 3). 



17. Pleonectusa aurata^ sp. n. 



Bright golden ochreous, with black markings as follows : — 

 primaries with a dot near base of costal vein, an oblique, 

 fairly well-marked line across basal seventh, a dot at centre of 

 cell, an oblique dash at end of cell, and a slightly sinuous, 

 transverse, tapering, discal stripe across external fourth : 

 secondaries with a small oblique dash at end of cell, and a 

 crinkled arched line just beyond the middle. Under surface 

 with the black markings better defined, excepting at base of 

 primaries, where they fail ; the veins for the most part also 

 black, and terminating in black dots, the fringes tipped with 

 grey ; the discal line of secondaries angular. Expanse of 

 wings 13 millim. 



Alu. 



18. Pleonectusa argentata, sp. n. 



Silvery white, slightly pearly towards the base : primaries 

 with a black dot near base of costal vein, a second at centre 

 of cell, and a conspicuous black spot at end of cell. Wings 

 below slightly tinted beyond the middle with golden and with 

 the veins greyish. Expanse of wings 24 millim. 



Alu. 



Evidently commoner than the preceding species.
