MA CROLEPIDOP TERA 



i^^ 



absence of dark strigulations ; subapical streak seldom marked ; in % median band and 

 terminal space beneath ajiex seldom suffused with dark fuscous. 



One hundred and twenty-six specimens, N.W. Koolau range, Oahu, in luly and 

 August. This extensive series shows the species to be variable in the same way as its 

 close allies ; it weakens the value of the dorsal approximation of first and second lines 

 as a distinguishing characteristic, but the species still appears to be distinct; the reddish- 

 ochreous tinge of ^ helps to distinguish it from isospora, and the small size from arnraea.

 The description may be extended by the following particulars : 

 ^ %. 32 — 42 mm. Head, thorax, and abdomen in ^ light fuscous, abdomen \\, 

 segmental margins whitish. Antennal pectinations in ,? 8 — 10, speckled and partially 

 lined with black. Legs in ^ dark fuscous, apex of joints ochreous-whitish, posterior 

 tibiae fuscous mixed with ochreous-whitish, moderately dilated, enclosing an ochreous- 

 whitish hairpencil, posterior tarsi f. Forewings in ^ with termen rather obliquely 

 rounded ; colour as in %, but darker and more infuscated, first, median, and second 

 lines darker, brown. Hindwings in both sexes with colour and lines usually as in 

 forewings, but first line obsolete. 



Twelve specimens, N.W. Koolau range, Oahu, in Jul)- and August. Previous type 

 unique ; it is a good and distinct species.

The following particulars are supplementary : 



^ %. 29 — 39 mm. Head and thorax usually more or less tinged with pale purplish. 

 Antennae in ^ whitish, pectinations 5, laterally blackish-lined. Abdomen purplish- 

 whitish, sometimes suffused with pale yellowish or sprinkled with dark fuscous, in ^ \\. 

 Posterior tibiae in ^ rather dilated, enclosing an ochreous-whitish hairpencil, posterior 

 tarsi f. Forewings with apex distinctly prominent, termen usually distinctly sinuate ; 

 varying much in colour, from pale ochreous to light ashy-fuscous, more or less strigulated 

 (sometimes densely, sometimes very slightly) with dark fuscous, often suffusedl)- 

 irrorated with ferruginous ; first and second lines pale, but varj-ing in colour with the 

 ground ; in very dark specimens the median line is obscured. Hindwings in $ paler 

 and somewhat tinged with ochreous-whitish towards dorsum. 



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

 type unique ; the species is very variable, but remains easily distinguishable.
