436 CANARIAN COLEOPTERA. 



This Zophosis (which is likewise from Grand Canary) is excessively 

 near to the last one, and is in some respects intermediate between it 

 and the bicannata ; nevertheless it is certainly more closely related 

 to the vagans than to the latter. It differs, however, from that species 

 in being a little more regularly oval, or just perceptibly wider in front ; 

 in its colour being of a deeper black, with a slight tendency to a sub- 

 cyaneous (rather than a subsenescent) tinge ; and in its elytra being 

 a little more even, or less maUeated, and with their costse a trifle 

 narrower — the second one of which is more abbreviated anteriorhj, 

 whilst the third is somewhat more straightly and sharply defined. Its 

 less rounded outline and very much more developed plicce will at once 

 separate it from even the most costate phasis of the biearinata. I have 

 observed it hitherto only in the region of El Monte in Grand Canary ; 

 but it is probably elsewhere diffused.

If it be admitted that the four states which I have indicated above 

 are but insular modifications of a single species (and I think it will 

 scarcely be possible to regard them as otherwise), the present Z-ophosis, 

 although extremely local, would appear to be more widely distributed 

 over the archipelago than any of the others here enumerated. Its 

 clytral costal, even when traceable, are excessively indistinct ; and it 

 would seem as if their greater or less development was dependent in 

 some way upon certain local influences which have served gradually
