144 INSECTA MADERENSIA. 



119. Tarphius brevicoUis, WoU. 



T. quadrato-ovatus piceo-ferrugineus valde et louge sctosus, prothorace rugoso bre\issimo lato, circa 

 medium subito dilatato et postice angustato, granulis obscurissimis obsito, canaliculato, clytris 

 submaculatis rugose subseriato-grauulatis, interstitiis alternis leviter elevatis interruptisj nodos 

 formantibus, tarsis in utroque sexu (nisi fallor) simplicibus.

Habitat in locis similibus ac T. echinatus, sestate rarissimus. 



T. short, more quadrate and oblong tlian the T. echinatus, and of a sligbtly darker, or more rusty, 

 ferruginous hue, not much incrusted with scales, but densely clothed with long, erect and rigid 

 seta;, — which however are shorter than those of the last species. Head and prothorax rough, 

 and beset with obscure and rather distant granules, which are so mixed up with bristles and 

 scales as to be but indistinctly perceptible : the latter deeply channeled, very short, suddenly 

 and greatly dilated in the middle, and narrowed before and behind, especially the latter, — which 

 causes the sides to be considerably cui-ved. Elytra more or less indistinctly spotted, more 

 parallel at the base than those of the last insect, rugoscly granuled (rather than punctured), and 

 wrinkled transversely, — the granules being more especially perceptible towards the outer margin, 

 and appearing to replace the punctures which are more or less evident in the whole of the pre- 

 ceding species, although somewhat intermingled with, and merging into, punctures towards 

 the suture; the alternate interstices slightly elevated and interrupted, forming small but very 

 distinct nodules in the usual positions, which with the ridges are rather more lightly coloured, 

 or rufescent, than the rest of the surface. Antemue and leys as in the last species. 



The distinctions between the present insect and the last hare been already 

 pointed oiit, — its more parallel, or oblong outline, added to its somewhat shorter 

 setue and darker hue, its more noduled, granulated, and less e^'idently pimctiu'ed 

 elj'ira, and the totally different form of its (deeply channeled) prothorax, being- 

 sufficient, even prima facie, to separate it from that species. It is extremely rare, 

 I)eing found, in company with its allies, in the damp wooded districts of lofty 

 elevations. 



120. Tai-phius nigosiis, Woll. 



T. oblongo-quadratus nigro-piceus, prothorace rugoso amplo, ante medium valde dilatato, lateribus 

 subajqualiter rotundatis, granulis dispersis obtusis obsito, canaliculato, elytris concoloribus rugose 

 granulatis, interstitio juxta suturam costato-elevato, reliquis valde interruptis, nodum exstantcm 

 longc pone apicem singuli situm formantibus, tarsis in utroque sexu (nisi fallor) simplicibus.

T. large, squarer than any of the other species, piceous-black, rough, apparently a good deal incrusted 

 with scales, and quite opake. Head and prothorax very rough, and beset with rather small, 

 distant granides, which are more or less concealed amidst the very short and robust seta^ with 

 which they are intermixed : the latter deeply channeled, very large, and much dilated about the
