From types wbicb bave been communicated to me by M. Cbevro- 

 lat, I am enabled to state for certain that Scbonberr's Laparocerus 

 tetricus is the Curculionid which I would desire now to characterize 

 — and not the preceding one : indeed the published diagnosis of it, 

 though far from accurate, is sufficiently clear on several points (par- 

 ticularly the punctation of the prothorax) to prevent its being con- 

 founded with that insect. Nevertheless it is unquestionably very 

 nearly allied to it — so much so, in fact, that until I had overhauled 

 the two critically I had regarded them as the sexes of a single species. 

 But finding, on closer examination, that I possess males and females 

 of both of them, and which present features which I had at fii'st 

 overlooked, I now perceive that such cannot be the case. It may be 

 known easily from the A. tibialis by being, on the average, a trifle 

 smaller and narrower, as well as rather more shining and of a deeper 

 black; by its prothorax being a little convexer and more lightly, 

 finely, and distantly punctured on the disc ; by its scutellum (although 

 minute) being perceptibly larger than is the case in that insect ; by 

 its elytra being a trifle less conjointly-emarginated (or more straiglitly 

 truncated) at their base, and with the punctures of their stria; perhaps 

 less immense ; and by the two hinder tibiae of its male sex being rather 

 scooped-out internally at a short distance from their apex, causing 

 them to appear curved inwards (and rather enlarged) at the tip. 



I have observed the A. tetrica only in Teneriife, and hitherto 

 merely at low elevations near S'" Cruz, where it woiild seem to 

 occupy much the same sort of position as the tibialis does around 

 Orotava. It was also found in the vicinity of S*" Cruz by the late 

 Rev. W. J. Armitage ; and it has recently been sent therefrom by 

 the Barao do Castello de Paiva, who captured it " in CacaUce bifurca- 

 tionibus " in the Barranco Santo. 



The Otiorliynclms simplex of M. Brulle appeared to me, from the 

 type which I examined in Paris, to be founded on nothing more than 

 an immature example of this species ; and indeed his description 

 (such as it is) would, I think, imply that it cannot be referable to the 

 A. tibialis, since he expressly states of the prothorax, " sa surface 

 inferieure et laterale est fortement ponctuee ; sa surface dorsale est 

 au contraire presque depourvue de points."
