220. Tomicus villosus. 



T. lato-cylindricus subnitidus piceo-ferrugineus et pilis longissimis erectis subfulvescentibus adspersus,

Habitat Maderam, sub cortice arborum, rarissimus : tria specimina, in castanetis Sanctse Annae Junio 

 exeunte a.d. 1850 a meipso reperta, sola vidi. 



T. rather short, tiiick and cylindrical, slightly shining, ferruginous or pale piceo-ferruginous, and 

 densely besprinkled with exceedingly long, erect and fulvescent hairs. Prothorax not very 

 convex, uniformly and roughly scabrous or granulated, but scarcely more roughened in front 

 than elsewhere, — where however it is rounded and produced ; and without any appearance of 

 either a dorsal channel or ridge. Elytra rough, and very deeply seriate-punctate (the punctures 

 being extremely large and distinct), and the interstices with a longitudinal row of very minute 

 punctures down each ; abruptly truncated behind, — where there is a deeply-impressed stria on 

 either side of the suture, which gradually vanishes in front, but without any tendency to addi- 

 tional asperity. Antenna and legs testaceous. 



A large and well-marked Tomicus; and readily known from the following 

 species by its (proportionably) short, thick and robust form, pale rufo-piceous, or 

 almost ferruginous, hue, by its extremely hairy and roughened sui-face, and by 

 the sculpture of its prothorax and el}i;ra, — the former of which moreover is not 

 expanded anteriorly, whilst the latter are comparatively mitch truncated at their 

 hinder extremity. It is a tolerably common insect throughout boreal and central 

 liurope, Ijut Avould appear in Madeu-a to be decidedly scarce, — where it is just 

 possible indeed that it may have been introduced from more northern latitudes. 

 Three specimens only have hitherto come beneath my notice, — all of which were 

 captured by myself, during the s umm er of 1850, from under the bark of Spanish 

 chestnut-trees in Senhor Louiz Acciaioly's vineyard at Santa Anna. 



221. Tomicus Dohmii, Woll. 



T. angusto-cylindricus nitidus nigro-piccus et pilis brevioribus subcrectis cinereis adspersus, pro- 

 thorace amplo subtilissime et parcc punctulato, ante medium subnodoso-convexo, antice dilatato 

 obtuse rotundato necnon mucronibus asperato, elytris minute seriatim punctatis (seriebus alternis 

 vix observandis), ad apieem leviter obliquo-truncatis, antennis pedibusque palUdo-tcstaceis.
