HALTICID^I. 



Masoni, of which indeed (despite its many constant points of dissimi- 

 larity) I cannot feel altogether certain that it may not be an extreme 

 insular modification. Like that insect it occurs at intermediate and 

 rather lofty altitudes, and seems to be attached to the various Echia 

 particularly a large species (perhaps the simplex) which is closely 

 related to the gigantic E. candicans, of Madeira, on which the L. 

 Masoni subsists. I have however observed it, likewise, at any rate 

 in Hierro, on the foliage of the common E. violaceum. The L. per- 

 similis has been captured, as yet, only in Teneriffe and Hierro ; but 

 we may expect it to be found more generally distributed.

So far as I have observed hitherto, this Canarian Longitarsus ap- 

 pears to subsist on the leaves of the fragrant Messerschmidtia fruti- 

 cosa principally at rather low, but sometimes at intermediate 

 altitudes, under which circumstances I have taken it abundantly in 

 Teneriffe, Palma, and Hierro. Although most thoroughly dissimilar 

 in its normal state to the L. persimilis, it is somewhat curious that 

 occasional highly-coloured examples of it should make so decided a 

 primd fade approach to the paler ones of that insect that it is almost 

 impossible to resist the inquiry whether it might not be an ex- 

 treme (unspotted) modification of the latter, brought about perhaps 

 by the adoption of a food-plant so totally different from the Echia. 

 As recorded however in my Canarian Catalogue, I believe nevertheless 

 (despite the existence of the very rare, and exceptional, individuals 

 just alluded to) that the two species are completely distinct.
