The type of this species is noted in the card-index of Dr Hunter's Collection as missing; but in Cabinet A, drawer 3, there is a specimen, misplaced under label

‘Hab. in Anglia’,

which answers the descriptions given by Fabricius and Olivier and resembles Olivier's figure of lineatus. This insect has been compared with modern examples of the species in the British Museum, and it is evidently the missing type.

Description of Type, Tritoma vittata Fab. Form elongate-ovate, the elytra narrowing in front and behind, convex, smooth and shining; the upper surface reddish brown with patches of black, the under parts and the legs light reddish brown with a scanty covering of very short and fine whitish hairs.

The head is reddish brown, oblong and insunk in the prothorax; a deep crescentic suture marks off the flattened frons from the convex clypeus. The vertex, frons and clypeus are thinly punctulate, the punctules bearing short yellowish white hairs; the labrum also is punctulate and lightly covered with fine hairs; the mandibles are angulate and the tips are produced as long and pointed blades; the other mouth-parts are imperfect in the specimen. The eyes, which are brownish black, oblong and rather narrow, extend from the vertex to the gula; the facets are large and very convex. The antennae are wanting; the bases of the antennae are situated between and above the eyes and on each side of the frons anteriorly.

The pronotutn is transverse, narrower than the elytra and plano-convex, the disc being a little raised; the front is deeply hollowed and has a thin translucent stridulatory membrane which fills the distinct notch in the middle of the excavated front margin and which projects slightly beyond it; the sides are bisinuate and contracted behind; the base is rather narrow, nearly straight and broadly margined; the front angles are strongly produced and almost sharp, the hind angles are sharply produced, nearly rectangular.
