(J Iviza (type) 



Columns as on p. 175. 



This variety was discovered by Boscii on Iviza and on the neigh- 

 bouring small islets La G-rosa, La Eedonia, and El Malvi. It is 

 quite distinct from the var. lilfordi, and in some respects approaches 

 the var. quadrilineata, whilst the var. lilfordi is perhaps more closely 

 related to the var. filfolensis.
