TARACHE LUCIDA.
Plate IV.—Fig. 8.
This is a small moth, not very commonly found in Teneriffe. It is met with by day along the coast, and up to an altitude of 2000 feet or more in rough rocky places, in April and up to June or July. The prevailing colour is a blue-grey. The fore-wings have a large square patch of white on the upper margin, and a smaller dot of the same colour towards the middle. The hind-wings are fringed with white, and have two or three patches of the same colour along their margins. In the male, the white on both wings is increased towards the base. It is not an English species, but is found in Europe and along the Mediterranean. The larva is a green or brownish grey, with three dark double lines on the thoracic segments; tufted, and with a white line on the back on segments 5 to 7, and with a dark stripe on the back, and a whitish line on the sides of the remaining segments.
