and broad behind, considerably wider than long, and minutely 
but not densely punctate, with a deep excavation of a rounded 
triangular form occupying the anterior two-thirds of the middle 
of the thorax, and a blunt conical tubercle in front. Elytra 
about the width of the thorax and twice the length, strongly 
striate on each side of the suture, with about twelve rows of 
punctures disposed in more or less irregular oblique rows on each 
elytron, some of the rows striate, the punctures rather small and 
distant on the first two rows, the others very coarsely punctate. 
Beneath piceous, reddish hairy ; legs reddish, the anterior tibiae 
bluntly tridentate. 
Long. 6|, lat. 3^ lines. 
176. Cavonus turritus, n.sp. 
Broadly ovate, convex, reddish-chestnut, nitid. Head small, 
transverse, depressed and thinly punctate, the clypeus narrower 
than the head, and nearly at right angles to it, with the sides 
and apex rounded ; the whole surrounded by a strong ridge, of 
which the clypeal suture forms the base. Thorax very transverse, 
the sides very prominently bulged out in the middle, the whole 
disk very deeply excavated, with a small tubercle on the anterior 
edge of the excavation, and a large turret-like elevation on each 
side of the excavation, terminating in a broad flattened slightly 
bifid summit, the interior of the excavation is smooth and densely 
villose, the turrits are coarsely punctate and nearly black, and a 
strong curved ridge crosses the front of the lower part of them, 
the end of which forms a tooth on the inner edge. Scutellum 
large, triangular, rounded behind, and finely rugose. Elytra as 
wide as the thoi'ax and one and a-half times the length, largely 
but not deeply rugosely punctate in irregular rows, a strong 
punctured stria on each side of the suture; beneath densely 
covered with long hair, the legs short and strong, the anterior tibiae 
tridentate, the posterior very large. 
Long. 9, lat. 5 lines.
