Art. LVIII.—Some New Species of Lepidoptera.
[Read before the Otago Institute, 12th September, 1905.]
♂, 42 mm. One specimen. Antennæ, legs, and face bluishgrey. Palpi bluish-grey, ochreous beneath. Crown ochreousgrey. Patagiæ grey margined with delicate blue. Abdomen ochreous, tinged with dark-grey dorsally. Anal tuft ochreous. Forewings light greyish-blue, all lines and markings as if pencilled on in darker colouring. Costa slightly arched, apex subacute, narrow suffusion along costa from base to apex. A very jagged transverse line close to base. A jagged transverse line at about ⅓ and another at ⅔, approaching each other in centre of wing, then bending sharply away and approaching again about centre of dorsum. A jagged transverse subterminal line, twice sharply dentate, near tornus. A clouded dark suffusion between this and line at ⅔ along costa. Portions of veins lightly outlined with darker scales. An undefined yellowish suffusion from costa to dorsum at centre of wing. Reniform obscure. Orbicular faintly shown, being lighter in colour than wing-centre. Cilia of forewings bluish-grey, slightly barred with grey. Hindwings bright-ochre, deepening to dark-fuscous towards termen, edging of dull-ochre along costa. Cilia long, ochreous-grey, with a faint fuscous basal line appearing very light by contrast with the darker cilia of the forewings.
This exceedingly beautiful moth was taken by Mr. Robert Gibb at Tuturau, near Mataura, attracted by light.
I am naming this moth after Mr. G. V. Hudson, as a slight recognition of the great good his entomological work has been to the southern workers.
Melanchra beata, n. sp.
♀, 38 mm. One specimen. Legs, antennæ, palpl, and face all reddish-brown. Thorax greyish-brown. Abdomen dull-grey, reddish below. Anal segment reddish. Forewings: Costa slightly sinuate at about ⅓. Apex subacute. Termen sinuate near tornus and oblique. General ground-colour delicate pinkish-brown. Three pairs slight dark marks on costa. A series of small obscure black dots along termen. Orbicular faintly out-lined in white, broadly oval, oblique. Clariform triangular, posteriorly outlined in white. Reniform outlined in white. A
faint light-brown irregular line near termen, ending in a blackish three-cornered blotch close to tornus, margined on terminal side with white. Cilia light-brown. Hindwings light-brown, deepening towards apical portion and towards dorsum. Cilia dark-brown edged with white.
Taken at blossom in November in bush at Ototara, near Invercargill.
Agrotis veda, n. sp.
♂, 30 mm. One specimen. Antennæ dark-fuscous, bipectinated. Palpi light-grey, with dark terminal joint. Thorax grey, extra pubescent beneath, tufts prominent. Head and anterior crest dark-grey. Abdomen silvery-grey. Slight anal tuft. Forewings silvery-grey, with a slight red suffusion. Reniform and orbicular are joined and outlined in brown, but not complete. A series of slightly darker markings between veinings of forewings. An interrupted brown line showing on costa at ⅓, and again at centre of wing, and as a faint mark on dorsum. Cilia grey. Hindwings grey, with faint darker terminal suffusion. Discal spot crescentic, fuscous. Cilia greyish-white.
From Motueka, Nelson.
♀, 37 mm. One specimen. Antennæ ochreous, filiform. Legs and palpi greyish-ochreous. Legs fuscous beneath. Face and thorax dark-ochre. Thorax moderately crested. Abdomen dull-grey; anal segment paler. Forewings uniform light-ochre. Veins plainly outlined in grey. Orbicular and reniform obsolete. Slight dark shading from base to half-way along wing-centre. Termen very slightly sinuate near apex. Hindwings uniform fuscous, with cilia light-ochreous as in forewings.
This moth appears to be close to L. arotis, but differs in coloration, in the absence of dots on the forewings, and in its pale-ochre cilia.
Taken in December in Dunedin.
