Lepidoptera from the South Pacific. 233 



73. Plconectusa chalinota, n. s. 

 c?, 21 mm. Head, palpi, antennce, thorax, abdomen, and legs 

 snow-white ; three apical segments of abdomen sharply blackish 

 above. Fore wings triangular, costa posteriorly gently arched, 

 apex tolerably rectangular, hind margin somewhat sinuate, oblique ; 

 snow-white ; a blackish discal dot before one-third ; a transverse 

 oval blackish discal spot before middle ; a similar spot on costa at 

 three-fourths, whence proceeds a nearly straight light ochreous 

 line to inner margin at four-fifths ; a small blackish apical spot, 

 connected with a slender interrupted dark fuscous streak along 

 hind margin, finely attenuated beneath ; cilia white, basal half 

 whitish ochreous, separated by an indistinct fuscous line ; veins 4 

 and 5 short-stalked. Hind wings with vein 7 anastomosing with 

 8 to beyond one-third ; snow-white ; a straight pale ochreous line 

 from costa beyond two-thirds to anal angle ; a dark fuscous hind- 

 marginal line, dilated at apex, not reaching anal angle ; cilia as in 

 fore wings. 



Solomon Islands and Ellice Islands (Mathew) ; several 

 specimens. 



Teematarcha, n. g. 

 Forehead rounded, oblique ; ocelli present ; tongue well de- 

 veloped. Antennie five-sixths of fore wings, in male filiform, 

 shortly ciliated (^), with projecting scales at joints. Labial palpi 

 moderate, arched, ascending, second joint with dense projecting 

 scales beneath, terminal joint very short, cylindrical, obtuse, some- 

 times concealed. Maxillary palpi moderately long, slender, fili- 

 form. Abdomen in male elongate, anal segment long, with small 

 anal tuft, valves retracted. Posterior tibiae with outer spurs about 

 half inner. Fore wings with vein 10 rising out of 9, 11 oblique ; 

 in male 4 and 5 closely appressed towards base, a circular im- 

 pression above in disc immediately beyond cell, 6 bent and shortly 

 fiu-cate at base in this, beneath with a longitudinal comb of dense 

 scales from beneath costa before middle directed towards disc. 

 Hind wings somewhat broader than fore wings ; veins 3, 4, 5 

 approximated at base, 7 out of G near origin, anastomosing with 8 

 to middle. 



Closely allied to Plconectusa, from which it differs 

 especially by the peculiar structure of the fore wings in 

 male. Bnuliua, Ld., must approach this very nearly, 

 but Lederer makes no mention of the conspicuous comb 

 or fold of scales on the under surface of fore wings, 

 which he could not fail to have noticed.
