"Eyes naked, not ciliated."
Genus 9.—BITYLA, Walk.
"Antennæ in male filiform, shortly ciliated. Thorax not crested, collar sub-erect. Abdomen not crested."—(Meyrick).
Of this genus we have two species in New Zealand.
BITYLA DEFIGURATA, Walk.
(Xylina defigurata, Walk., Suppl. 756. Bityla thoracica, ib. 869. Bityla defigurata, Meyr., Trans. N. Z. Inst. xix. 31.)
(Plate [V]., fig. 33.)
This species has been taken at Palmerston in the North Island, and at Blenheim, Christchurch, Lake Coleridge, Dunedin, and West Plains near Invercargill, in the South Island.
The expansion of the wings is 1½ inches. The fore-wings are uniform dull bronzy-brown and very glossy; there are one or two faint indications of transverse lines. The hind-wings are dark grey, also glossy.
The perfect insect appears in January, February, and March, and is attracted by light. The single specimen I possess in my collection was taken in July, evidently hibernating. It is a rare species.
