Mr. Scott Wilson, writing to the author of his visit to the Isle of Palma, states that the Queen of Spain Fritillary (Argynnis Lathonia) is very common in the meadows near the town of El Paso, 2000 feet above the sea level in May. In the same month he noticed the clouded yellow (Colias Edusa) in large numbers in the clearings amongst the pine-woods. A few specimens of the large Fritillary (Argynnis Maia) were secured by him at El Paso early in May, where the Vulcania was also found; of these latter specimens only two out of one hundred proved to be of the British form Atalanta. The Bath-white (Pieris Daplidice) was common near Argual.
The Danais Chrysippus appeared rather uncommon, only a few specimens being taken near the barranco Del Carmen, not far from the town of Santa Cruz, and a few near Tijarafe.
Specimens of the small blue (Lycaena Webbiana) were taken near Argual.
In the middle of May the large white (Pieris Cheiranthi) was commonly found on the large laurel-trees at La Galga.
The author believes that the same species of Lepidoptera are generally distributed over all the seven islands, but that in Fuerteventura and Lanzarote, both of which are dry, sandy, and somewhat barren islands, they are not found in such numbers or variety. It is probable that different species of small African moths, some of which are enumerated on pages 93-4, may be found in Lanzarote, which is the nearest island to the coast of Africa, and which more closely resembles it in climate and vegetation, in greater numbers than in Teneriffe. The Euphorbia, which grows so plentifully in most of the islands, is uncommon in Lanzarote; hence the D. Tithymali, abundant in Teneriffe, would be scarce in this island. The lack of water in Fuerteventura, and consequent sparse vegetation, is doubtless the cause of the scarcity of Lepidoptera in that island, though the interesting occurrence of the insect “Euchlöe Charlonia,” a North and West African butterfly (which has only once been recorded as having been observed in Teneriffe), is accounted for by the proximity of the island in question to the African mainland. This species probably occurs in Lanzarote, for the same reason; it will doubtless become dispersed over the remaining islands in time.
