iMACROLEPIDOPTERA 353 



Scotoiythra paratactis, sp. nov. 



^ 23 — 25 mm., % 26 — 32 mm. Head and thora.\ brownish more or le,ss mi.xed with 

 whitish-ochreous, on front of crown usually with a whitish-ochreous defined patch or 

 fillet. Antennae whitish-ochreous, usually spotted with dark fuscous, pectinations in 

 t 6, blotched with dark fuscous. Abdomen pale whitish-ochreous sprinkled with 

 fuscous, in J 1^. Legs ochreous-whitish spotted with dark fuscous, posterior tibiae in .^ 

 dilated, enclosing an ochreous-whitish hairpencil, posterior tarsi in ,? almost i. Fore- 

 wings elongate-triangular, termen hardly waved, bowed, rather oblique ; pale fuscous, 

 pale brown, ochreous-brown, or (in one %) pale yellow-ochreous, more or less strigulated 

 with dark fuscous (in the yellow-ochreous specimen very obsoletely) ; first and second 

 lines represented by thick undefined darker shades, first bent above middle, second 

 somewhat bisinuate ; in the darkest specimen these include a little whitish suffusion ; 

 discal spot large, undefined, darker ; subterminal line obsoletely indicated by cloudy 

 darker margin, more suffused terminally; a terminal series of blackish dots. Hindwings 

 with termen unevenly waved ; whitish-fuscous, strigulated with grey ; an irregular 

 entire dark grey postmedian line, sometimes faint or obsolete ; termen sometimes 

 darker-suffused. 



Five specimens, Waianae coast, Oahu, in January ; two of these bred from larvae. 

 Very variable in colour, and intensity of markings ; perhaps nearest 5". iiiscia, but 

 easily distinguished by the smaller size, absence of median line of forewings, and 

 variability.

 I have recorded this from Maui.

The Oahu examples of this species form a distinct geographical race, for which I 

 propose the name cocytias, characterised as follows : 



? 30 — I}, mm., % 34 — 40 mm. Smaller and darker than type, forewings almost 

 wholly sufiused with dark fuscous, but the two brownish bands usually perceptible .' 

 discal spot often obsolete, but in one specimen white, pearshaped. 



Seventeen specimens, N.W. Koolau range, Oahu, in April, July, and August. 

 I do not think this can be regarded as a species, since extreme forms barely differ 

 irom typical nephclostiita, but the ordinary examples are distinct enough ; it is in fact a 

 geographical form which is on the verge of becoming a species by the elimination ot the 

 reversionary tendency.
