CANARIAN COLEOrXERA. O 



of that insect that it will not be possible to treat them, at the utmost, 

 as indicative of more than a mere geographical variety (and that too 

 an exceedingly trifling one) of the same species. But, whilst thus 

 expressing my conviction that it will be found, when further material 

 has been obtained, to be coincident with the azoricum, I do not wish 

 to ignore the fact that, in the Canarian insect (judging from the 

 examples now before me), the prothorax is not quite so straightened 

 (obliquely) behind, and therefore not quite so preceptibly subangu- 

 lated on either side in the middle ; and that the elytra are somewhat 

 less closely reticulated, a trifle more rectangular at their shoulders, 

 and with the punctui-es of their triple series apparently rather more 

 numerous. Pei'haps also its intermediate (female) tibiae are not quite 

 so straight, though the difference (if any) is scarcely perceptible. 

 If, when the male sex has been discovered, it should prove to be 

 distinct from the azoricum (which, however, I think is very unlikely), 

 I would propose for it the trivial name of canariense. 



From the C. indagator the present Calosoma may be known by its 

 prothorax being a little smaller and rather more narrowed behind 

 (which causes it to be a trifle less obtusely rounded, or more sub- 

 angulated, on either side in the middle), with its posterior angles 

 perceptibly acuter, or more downwardly-produced, and with its basal 

 fovese larger and deeper ; by its elytra being somewhat more roughly 

 and closely imbricated, a little more rectangular' at the shoulders, 

 and with the metallic points of their three longitudinal series rather 

 more numerous ; and by all its tibiae, at any rate in the female sex 

 (for which I can alone speak), being straighter, and perhaps a trifle 

 longer and slenderer.
