INSECTA MADERENSIA. 143 



coloured than the rest of the surface. Antenna and leffs as in the preceding species : the latter 

 with the ta7-si simple in both sexes. 



The small size and parallel outline of the present species, in conjunction with 

 its rigidly, though somewhat shortly setose surface, and the comparatively trun- 

 cated, or abruptly-shortened hinder portion of its elytra, will suffice to discrimi- 

 nate it from its allies. In its submaculated and nodose elytra it approaches the 

 T. brevlcollis; nevertheless its comparatively short setre, added to its narrower 

 and less ovate form, and its entirely different prothorax, at once remove it from 

 that insect. It is one of the rarest of the genus, and is taken in company with 

 the other species, — although, as will he perceived by a reference to the umnerical 

 table given above, exceedingly sparingly. 



118. TarpMus echinatus, Woll 



T. ovatus valde et longissime setosus ferrugineus, prothorace brevi rugoso, circa medium dilatato, 

 granulis obscuris obsito, elytris submaculatis rugose seriato-punctatis, interstitiis alternis leviter 

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

T. short and ovate, more or less ferruginous, not much incrusted with scales, but densely clothed with 

 very long, erect and rigid setae. Head and prothorax rough, and beset with rather small, obtuse 

 granules, — which, from the bristles and scales with which they are intermingled, are usually 

 somewhat obscure : the latter not channeled (or very indistinctly so), rather short and wide, 

 most dilated about, or a little before the middle, but with the sides not greatly curved, — the 

 anterior and posterior portions being subequally attenuated. Elytra rather rounded behind, 

 submaculated, — having exceedingly obscure patches in the usual positions, which appear, 

 normally, to be much diffused over the elytra (thus diluting their surface) and to take the form 

 of ill-defined blotches rather than distinct spots ; rugosely seriate-punctate, the punctures being 

 large and distinct ; the suture and alternate interstices a little raised and somewhat interrupted, 

 though scarcely sufficiently so as to form nodules. Antennce and legs rather paler than those of 

 the last species : the latter with the tarsi (I believe) simple in both sexes. 



The present species and the T. brevlcollis are readily separated from the re- 

 mainder of the genus by the comparatively long and erect bristles with which 

 they are beset. At first sight they would appear to be, inter se, a good deal 

 allied ; but a more accurate inspection will disclose abundant characters by which 

 they may be distinguished from each other. Thus, the more rounded, or ovate 

 outline of the T. ecldnatus, in conjimction with its ferruginous hue, the greater 

 length of its bristles, and its much less basally-constricted (or medially dilated) 

 prothorax, ■ndll, apart from minor points, be more than sufficient to prevent the 

 possibility of confounding it with that insect.
