ASPILATES COLLINARIA. (Holt-White.)
Plate IV.—Fig. 10 (Female).
This moth is allied to the Aspilates Gilvaria, but is probably an insect peculiar to the Canaries. It measures in expanse about one inch. It is of a pale buff-colour, the female being of a much intenser shade than the male. The hind-wings in both sexes are much lighter in colour than the fore-wings. The fore-wings of the female have a slate-blue narrow band of colour, extending from near the apex to the base of the upper margin, forming a semicircle. Within the semicircle, and near the upper margin, is a small slate-blue dot. The hind-wings have also a band of varying width and of the same colour extending across them, and a slate-blue dot is seen near the top of the upper margin above the slate band. The male has similar markings, but they are much paler, and not nearly so well defined. The antennæ of the male are feathered, of medium length; those of the female are longer and finer. At first sight this moth might be deemed a variety of Sterrha Sacraria. The female was taken at Guimar about 1000 feet above the sea. Several male specimens were taken near Orotava, at a somewhat higher altitude. This moth, being unknown at South Kensington, has been named as above by the author.
