Like the C. hrunneipennis, the present Coptostethus is exceedingly 

 variable in all its characters. It is the only one that I have taken 

 hitherto in Grand Canary ; and, in its normal state at all events, it 

 may be known from all other species here described by its rather 

 obtuse, thickened, and more pilose body ; by its prothorax and elytra 

 being, each of them, less contracted at their respective bases; and 

 by the latter being but very finely crenate-striated, with their in- 

 terstices depressed, and with their pile denser and more erect. Its 

 elytra are extremely inconstant in hue, being sometimes quite dark 

 and concolorous, and at others more brightly rufescent towards the 

 shoulders than is the case in any of the preceding species — under 

 which circumstances the reddish dash frequently extends backwards 

 more than half-way to the apex. 



The C crassiusculus seems to be peculiar to Grand Canary. I 

 have taken what I regard as the normal phasis of it in the region of 

 El Monte ; but the form in which the prothorax and elytra are a 

 trifle less pubescent and somewhat narrower at their respective bases, 

 with the striae of the latter a little dee^jer and the interstices more 

 convex, appears to occur at a higher elevation, — for I have captured 

 it both on the mountains above San Mateo and in the lofty Pinal of 

 the district of Tarajana, above San Bartolome.
