264 INSECTA MADERENSIA. 



l)y the enormous punctiires and conspicuous fasciae of its comparatively ovate 

 elytra. I have dedicated the species to my friend Richard Dawson, Esq., M.D., of 

 London, to whom I have been indebted for much kindness throughout many years ; 

 and whose microscopic researches, in a higher department of natural science, have 

 been long made known. 



201. Ptinus pingTiis, Wall. 



P. piceus squamis cinereo-fulvescentibus dense tectus, clytris rotundatis impunctatis, fascia posticA 

 obsoletissima (saepe omnino obliterate) ornatis, antennis pedibusque ferrugineis et dense squa- 

 mosis, illis in man; (?) robustioribus.

 Rev''° Doin. Lowe a Madera boreali communicatum. 



P. Ijfownish-piccous, and densely clothed with yellowish-cinereous scales (which often assume, espe- 

 cially on the prothorax where they are more thickly set, a slightly golden tinge). Prothorax 

 rather convex, tian-ow, and scarcely at all rounded at the sides ; and, normally, with obscure 

 indications of a white line down the centre, and another on either side. Elytra exceedingly 

 round and convex (being widest about the middle) ; rather less densely clothed with scales than 

 the prothorax ; impunctate ; and, in highly coloured specimens, with a very obscure paler 

 posterior patch on each (to indicate the usual hinder fascia, — the basal one being quite obsolete). 

 Antenna and legs robust, especially in the males (?), ferruginous, and densely clothed with 

 yellowish-cinereous scales ; the former nearly filiform, with their apical joint thick and ovate ; 

 the latter with their tarsi not very short, but rather broad at the base. 



Easily distinguished from the remainder of the genus here described by its 

 entirely unpunctate svu-face; — a peculiarity which, in connexion with its obese, 

 extremely roxmded form, and the yellowish and somewhat silken scales with which 

 it is uniformly clothed, gives the insect, jiHmd facie, a rather greasy, or oily 

 appearance. Like the following species, it would seem to be scarce : nevertheless 

 I have captured it near Eunchal (I believe in the Eibeiro de Santa Ltizia), and I 

 possess an old specimen from the collection of the late Dr. Heinecken ; wliilst 

 another has been recently communicated to me by the Rev. R. T. Lowe, by whom 

 it was taken in the north of the island, at Sfio Vincente. 



202. Ptinus orbatus, Woll. (Tab. V. fig. 6.) 



, P. ferrugineis squamis subfulvescenti-cinereis parce tectus, elytris subovato-rotundatis subseriato- 

 punctatis (punctis magnis rcmotis), fascia subpostica obsoletissimA ornatis, antennis pedibusque 

 brevibus robustis et \-ix dense squamosis.
