CANARIAN COLEOPTERA. 311 



thorax is somewhat shorter and more roughly punctured ; its anterior 

 tibiae have an evident tendency, particularly in the males, to be sub- 

 arcuated, and are also in that sc\v armed at their inner apical angle 

 with an extremely diminutive spine* ; and its rostrum is a trifle slen- 

 derer, and is but faintly thickened at the point where the antennoB are 

 inserted into it — instead of being (as in that insect) conspicuously 

 tubercled. 



493, Apion Westwoodii, n. sp.

 I have much pleasure in dedicating this the most distinct and beau- 

 tiful of all the Canarian Apions to my friend Professor Wcstwood, of 

 Oxford, whose long and varied labours in the cause of Entomological 

 science have justly placed him in the foremost rank of the European 

 naturalists. It may immediately be known by the robust, brownish- 

 yellow or dirty yellowish-white, decumbent pilifomi scales with which 

 it is sparingly clothed ; by its otherwise dark hue, though more or less 

 brassy and shining elytra (which have their striae deep and coarse, 

 though very obscurely crenated) ; by its alutaceous head and pro- 

 thorax (the latter of which is also deeply, but not very closely, punc- 

 tured) ; by its almost unsculptured interstices ; and by its long, slen- 

 der, linear, arcuated, bright, and finely punctulated rostrum. 



The A. Westwoodii is peculiar, so far as I have observed hitherto, to 

 the mountains of Grand Canary — where, during the spring of 1858, 1 

 captured it in the region of El Monte ; and also (though more sparingly) 

 on the lofty Pinal of Tarajana, above San Bartolomc.

* This character is, however, indicated (though less distinctly) in the cardu- 

 onim; as well as in certain other European species, — as, for instance, in the mncum 

 and radiolus, and very obscurely in the male of onopordi. It likewise exists in 

 the chalybeipenne.
