11. Cr. vittellus, Dbld. (Crambus vittellus, Dbld., Dieff. New Zeal., Vol. II., 289; Crambus nexalis, Walk., Brit. Mus. Cat., 178; Crambus transcissalis, ibid., 178; Crambus sublicellus, Z., Mon. Cr., 31; Crambus bisectellus, ibid., 32; Crambus incrassatellus, ibid., 32; Crambus vapidus, Butl., Proc. Zool. Soc. Lond., 1877, 399.) Male, female.—20–25 mm. Head white, a spot on face and posterior margins of eyes very pale greyish-ochreous. Maxillary palpi white, towards base externally greyish-ochreous. Labial palpi moderately long, white, externally greyish-ochreous or brownish-ochreous. Antennæ dark fuscous. Thorax white, more or less ochreous on sides. Abdomen ochreous-whitish, more ochreous towards base. Legs whitish, beneath suffused with dark fuscous. Forewings moderate, in female rather narrow, costa gently arched, apex rounded-acute, hindmargin nearly straight or very slightly sinuate, moderately oblique; greyish-ochreous or brown, darkest on costal half; sometimes irrorated with whitish scales towards inner margin and posterior half of costa; often a more or less distinct suffused white streak extending along more or less of posterior half of costa, broadest at ¾; a moderate nearly straight central longitudinal white streak, rather attenuated at base, extending to hindmargin, sometimes attenuated posteriorly, margins often irregular on posterior half, sometimes suffusedly margined with dark fuscous on basal half beneath and on posterior half above, often irregularly interrupted by the transverse lines; extremity of median streak produced upwards into a narrow white projection along hindmargin nearly to apex; sometimes two transverse darker lines or series of spots, more or less distinctly cutting median streak, first from middle of costa to ⅓ of inner margin, very acutely angulated above streak, second from ¾ of costa to before anal angle, less acutely angulated; inner margin sometimes white towards base; three or four tolerably distinct black dots on hindmargin below middle; a tolerably distinct slender dark fuscous hindmarginal line: cilia shining-grey or whitish-grey, with a somewhat darker basal line, three or four slender white bars on upper half, sometimes confluent at base, and another above anal angle. Hindwings whitish-fuscous-grey, paler towards base, darker at apex; cilia ochreous-grey-whitish. This very common and very variable species, which may be regarded as the type of the New Zealand representatives of the genus, may in all its forms be sufficiently well distinguished from those with which it is most likely to be confused, by the white bars of the cilia, and the black hind marginal dots below median streak. It most approaches C. dicrenellus and C. flexuosellus, differing further from the former in the white costal suffusion not extending towards base, and from the latter in the central position of the white streak, and the paler costal area.
