impresso, prothorace brevi insequali, leviter canaliculato et postice utrinque foveolato, elytris sub-

Habitat sub lapidibus Maderas, et borealis et australis, toto anno frequens. 



T. ovate (being rather inflated posteriorly) and opake, brownish-black, and very densely clothed with 

 brownish-cinereous scales, — which often assume more or less of a rusty or ferruginous bue. 

 Rostrum rather long and almost linear (being of nearly equal breadth throughout), obscurely 

 channeled in the centre, and with a straight transverse impression, or striga, immediately before 

 the base. Prothorax short and transverse, and with the sides much rounded, — ^being widest just 

 behind the middle ; truncated both before and behind ; rather uneven, and with a shallow 

 central channel and a (more or less distinct) rounded fovea on either side behind. Elytra widest 

 behind the middle and very convex ; subpuuctate-striated ; the interstices ratber convex, usually 

 a little tessellated, and each beset with a single row of ratber short, suberect and very stiff setae. 

 Antenna and legs brownisb-ferruginous, and densely clothed with scales and setfe; the latter 

 rather short. 



A ttniversal insect througliout Europe, and tolerably common in Madeira at 

 rather low and intermediate elevations, — occurring bencatli stones on the grassy 

 slopes both in the north and south of the island, and at aU seasons of the year. I 

 have taken it in the neighlwurhood of Funchal, at Sao Vincente, and in the chest- 

 nut-woods of Santa Anna, at times, in comparative abundance.
