[2] During the winter of 1892-1893 it was met with in great numbers.
EUCHLOË CHARLONIA (Donzil).
Plate I.—Fig. 4.
This butterfly was seen near Orotava, 500 feet above the sea-level, during the first week in May by the author, who, however, was not fortunate enough to secure a specimen. Several specimens of this species, which is rare in the Canary Islands, have been netted in the island of Fuerteventura, and two of them have been presented by Mr. E. H. Hodges, of Rugby, to the British Museum, from which the illustration has been drawn. It measures in expanse about an inch and a half. The general colour is yellow, varying in intensity of shade in different specimens, with black apical markings on the fore wings and a long black patch on the centre of the upper margin. A full account of this interesting insect is to be found in Ann. Soc. Ent. Fr., 1842, p. 197, f. 1, but hitherto it has not been recognized in Teneriffe as a species belonging to the island. It is found in North and West Africa.
APORIA CRATÆGI.
This specimen is the rare English Black-veined White butterfly. It has undoubtedly been netted in Teneriffe, though it has not been personally observed by the author. In flight its similarity to other white specimens is so great that it may often be passed unnoticed. It is said to be local and uncertain in appearance, being seen chiefly during the summer months about the fields and gardens. The wings are entirely of a white cream colour, and are alike on both sides, the veins being black, and the fore-wings having some dusky spots on them. The caterpillar is black, thickly sprinkled with whitish hairs, and with a reddish yellow stripe running along each side. It feeds on various fruit trees, and is believed to be very destructive.
RHODOCERA CLEOBULE.
Plate I.—Fig. 3.
This finely-coloured and beautiful butterfly resembles the English Brimstone, but is quite a distinct variety, being of squarer form and having no decided point at the angle of the hind-wings. It is peculiar to the Islands. The male is a most brilliant sulphur yellow, the fore-wings being of a deeper shade than the hind ones. The hind-wings have a deep orange spot about the centre. The female differs from the male in being of a much paler shade of yellow, with quite a tinge of green all over it; it also has a small orange spot on the fore-wings in addition to that on the hind-wings. Both wings have red markings round them on the outer edge, which form an almost interrupted fine line of colour. The underside resembles the upper, but is paler. The antennæ are short and thick, with a reddish tinge, which becomes deeper at the knob.
