Habitat Canariam Grandem, in regione El Monte vulgaris. 

 This little Gnopliota appears to be universal throughout the region 

 of El Monte, and around Las Palmas, in Grand Canary ; and it may 

 be known from the cribricoUis by being, on the average, smaller, pro- 

 portionally shorter and more convex, more shining, and more deeply 

 and closely punctured (this last distinction being a very conspicuous 

 one as regards the elytra) ; by its prothorax being relatively a little 

 wider and more transverse, straighter (or less bisinuated) along the 

 posterior edge, and with the hinder angles rather roimder, or more 

 obtuse ; by its scutellum being perceptibly smaller, its elytra more 

 straightly truncated at their base, and its limbs shorter and some- 

 what more robust. The last of these characters is exceedingly evident 

 so far as the antennal joints are concerned, the third one of which 

 is much less decidedly elongated than in the cribricoUis. M. Brulle 

 manifestly alludes to this species as a mere state of his Hegeter cri- 

 bricoUis ; but such could only have arisen from a most superficial in- 

 spection, and from his not having perceived its real distinctive features 

 at aU.
