This well-defined species appears to be peculiar to Grand Canary, 

 where it is probably universal at low and intermediate elevations. 

 During the spring of 1858 I took it throughout the region of El 

 Monte, particularly on the Bandama mountain ; as also, in tolerable 

 abundance, at Arguiniguin, in the south-west of the island ; and it 

 was captured by the Eev. R. T. Lowe in the Isleta (to the north of 

 Las Palmas). It may be known immediately by its rather narrow 

 and subcylindric outline, intensely black hue, and minutely pubescent 

 siuface (which is studded on the elytra with long, erect additional 

 hairs), by its rather thick rostrum (which is 7iot concave above, as 

 is the case with the three preceding species), by its prominent eyes, 

 by its roughly punctured and somewhat convex prothorax (which is 

 strongly margined along its posterior edge), and by its sexes being 

 almost identical in their external features. 



Genus 213. LAPAROCERUS. 



Schonlierr, Gen. et Spec. Cure. ii. 530 (1834J. 

 As may be gathered from a glance at the following pages, Lajmro- 

 cerus plays a most significant part amongst the Canarian Curculionicla; 

 — no less than thirty well-defined species having already been de- 

 tected throughout the archipelago. It is intimately allied to the 

 genus Atlantis, which is so strongly expressed at the Madeiras, but 

 which seems to have but few representatives (and those somewhat 

 aberrant ones) in these islands. It would appear indeed that, whilst 

 both genera are foimd in the two Groups, Laparocerus is as essentially 

 Canarian as Atlantis is Madeiran — since but three exj)onents of the 

 former have hitherto been observed in Madeira, whilst of the latter 

 only five ahnormal ones have yet been brought to light at the Cana- 

 ries. Apart from minor distinctions, the Laparoceri may be known 

 immediately from the Atlantides by the construction of their scape 

 — which is excessively slender but suddenly clubbed at its extreme
