Mr. T. V. Wollaston on Additions to Madeiran Coleoptera. 365 



large, thickened, subtriangular basal one (of the funiculus) and 

 the ckib, that it was some time before I succeeded in separating 

 them at all inter se, — having regarded them at first as a single 

 articulation. But having succeeded at last in mounting an an- 

 tenna in a slightly curved position, so as to display this small 

 portion to the greatest possible advantage, it became a compara- 

 tively easy matter to recognize it as made np of three subequal 

 parts. Thus, in the Madeiran members of the Tomicida, we 

 have the funiculus composed in Aphanarthrum of three joints, 

 in Leiparthrum and Cryphalus of four, and in Tomicus and i/y- 

 pohorus of five. The C. aspei'icollis is powerfully winged, the 

 wings being densely and minutely irrorated all over with black 

 points or punctules (but almost free fi-om veins), and ciliated on 

 their lower edge with long hairs ; its tibiae are compressed and 

 externally spinulose. 



Cryphalus aspericollis, n. sp. 



C. minutissimus, cylindricus, subiiitidus, nigro-piceus et setulis rigidls 

 suberectis cinereis adspersus; prothorace irregulariter subpunctato- 

 ruguloso, ante medium subnodoso-convexo, antice obtuse rotundato 

 necnon mucronibus valde asperate ; elytris minute seriatim punc- 

 tulatis et longitudinaliter setosis, ad apicem integris ; antennis 

 pedibusque pallidis.

C. minute and cylindrical, slightly shining, dark piccous- 

 black, and sprinkled all over with rigid, suberect, cinereous, 

 scale-like hairs. Prothorax irregularly but lightly punctured, 

 and rugulose, with a small convexity on its fore disk (where it 

 is occasionally a little more diluted or rufescent), and greatly 

 roughened in front with coarse tubercles and points. Elytra 

 very lightly seriate-punctate, and with a row of excessively mi- 

 nute punctules down each of the interstices; the setae regularly 

 disposed in longitudinal rows; rounded and entire behind. 

 Limbs paler. 



In its cylindrical outline and anteriorly roughened prothorax, 

 the present minute wood-borer has all the appearance of a dimi- 

 nutive Tomicus; nevertheless, its elytra liave no tendency to be 

 obliquely truncated behind, and, as already stated, its funiculus 

 is only 4-artieulate. I detected it in abundance beneath the 

 dry dead bark of a rotten chestnut })aling, above Porto da Cruz, 

 in the east of Madeira pr()i)er, during December 1858; and it 

 was subsequently captured by Mr. Bewicke and myself, in the 

 tinder-like wood of an old fig-tree, at the Feij'ua dos Padres, 

 beyond the Cabo Geram. And I have also taken it, from out of 

 dead geranium-stems, above the Puerto of Orotava, in Teueriffe.
