Specimens of the small blue (Lycaena ^Webbiana) 

 were taken near Argual. 



In the middle of May the large white (Pieris Ohei- 

 ranthi) was commonly found on the large laurel-trees 

 at La Galga. 



The author believes that the same species of Lepi- 

 doptera 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 un- 

 common 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
