INSECTA MADERENSIA. 135 



transversely wrinkled (the punctures when the scales are removed appearing in very evident 

 rows) ; each ornamented with rufous or rufo-testaceous spots, which are arranged, typically, as 

 follows : — a large oblong one at the inner base, parallel to and alongside the suture ; a rather 

 narrower one (likewise elongated) towards the margin and in front of the shoulder, but extending 

 nearer to the apex than the last ; a small roundish one on the inner disk ; and two large ones 

 behind, — one towards the suture and the other towards the margin, — which usually, as in most 

 of the spotted species, become confluent, and form an irregular arcuated fascia which has its 

 concavity turned towards the apex of the elytron. Antenna and tarsi ferruginous : the latter 

 simple in both sexes. 



The smallest of the Tarphii here described, and readily known (apart from its 

 maculated surface) by the rounded hinder angles of its comparatively sublunulate 

 prothorax. It is the only member of the groixp wliich I have hitherto detected 

 out of Madeira proper, — being extremely abundant, during the winter and spring, 

 amongst lichen in the fissures of the exposed weather-beaten rocks of Porto Santo. 

 I first discovered it in April 1848, on the northern side of the extreme summit of 

 the Pico de Pacho ; and diuing December of the same year it occurred in literal 

 profusion on the ascent of the Pico d'Anna Perreii'a from the east. In Madeira it 

 would appear to be extremely rare, although widely distributed over the sylvan 

 districts between the limits of from 3000 to about 4500 feet above the sea. It 

 seems to be more peculiarly attached than any of the other species to lichen, 

 ascending, in the forest regions, to the highest branches of the trees, — as I have 

 proved (not without some risk) l)oth at the Ribeiro Prio and the Panal. During 

 my encampment at the Lombo dos Pecegueiros in July 1850, I captm-ed it by 

 brushing the rank vegetation immediately outside my tent, in the dusk of the 

 evening, — at which time its nocturnal wanderings, like those of the other repre- 

 sentatives of the genus, may be said to commence.

T. large, oblong, parallel and somewhat cylindric, dark piceous, generally but slightly covered with 

 scales, and a little shining. Head and prothorax rather smooth, and closely beset with large and 

 very obtuse granules : the latter not channeled (or, occasionally, most obscm-ely so), subquadrate 

 (the sides being comparatively straight), and in its widest point scarcely equalling the elytra in 

 breadth. Elytra concolorous, seriate-punctate (the punctures being large, particularly in the 

 female, — though rather shallow upon the disk), and but very slightly (especially in the male
