CAXARIAN COLF.OPTERA. 305 



winter and (more particularly) the spring months, from the sea-level 

 to an altitude of about 3000 feet. On the rocky ground along the 

 shore, between the Puerto Orotava and the Lazaretto, I have cap- 

 tured it sparingly, from beneath stones ; but a little below the alti- 

 tude of the Villa it becomes more common — being at times, and in 

 certain spots, extremely abundant. It differs from the L. auctus in 

 being, on the average, more brightly tessellated, and beset all over 

 with very evident and rigid (though at the same time short) setae ; 

 in its prothorax being more coarsely punctured, a trifle longer, less 

 rounded at the sides, and free from the glabrous abbreviated keel 

 which is there so evident in the centre behind ; in its elytra being 

 more oblong (or a little straighter at the sides, with the shoulders 

 more porrect but obliquely truncate, and slightly scooped-out con- 

 jointly along the basal edge), as well as more deeply punctate-stri- 

 ated and more drawn-out towards the apex ; and in its antennae 

 being perhaps a trifle longer, with their scape even thicker still (at 

 any rate at the base) and more flexuose, and with their funiculus 

 slenderer — the second joint being distinctly narrower than the first, 

 and the remaining ones somewhat less moniliform.

So very closely does the present Liclienopliagus resemble the L. 

 tesserida that until lately I had regarded it as a variety of that 

 insect ; nevertheless, after a careful examination of a very extensive 

 series of them both, I find that (however slightly so) the antennae of 

 the L. persimilis are so invariahly longer than those of its ally, and 

 with their scape so conspicuously slenderer, that I cannot but believe 

 it to be specifically distinct ; and more particularly so since it is not 

 confined to merely a single district, or even island (which would 

 probably be the case were it but a phasis of the other), but is found 

 equally in both Teneriffe and Palma. In minor respects it is, on the 

 average, a trifle larger and paler than the tesserida ; and the Palman 

 examples have the longitudinal rows of short setae with which the 

 elytra are beset somewhat longer and paler (and therefore more per- 

 ceptible) .
