tion), the elytra each with two velvety-black spots—one, oblique, rather large, at the middle of the disc, the 
other small, on the subapical callosity ; the vestiture of the under surface sparser, the abdomen with the 
sides only squamose. Rostrum very stout, curved, scarcely longer than the prothorax, rugulosely punc- 
tate and subcarinate, the antenne inserted near the tip, joints 3-7 of the funiculus very short, together 
barely so long as the club. Prothorax as long as broad, conical, feebly constricted towards the apex, 
minutely punctate. Elytra one-half wider than the prothorax, elongate-triangular, depressed on the 
anterior portion of the disc, the subapical callosities tuberculiform ; with rows of shallow punctures placed 
in fine striw, the interstices alutaceous. Ventral segments shining and almost smooth (the sides excepted), 
1 and 2 slightly pilose down the middle, 5 with a broad deep excavation, which has a small tuft of hair 
on each side at the tip. Legs long, rather slender; the tibie each with a long spur, the posterior pair 
strongly bisinuate. 
Length 5, breadth 2 millim. (<.)

One example, in rather dirty condition. This insect might be mistaken for a small 
Hilipus, but it may be easily separated from that genus by the ascending epimera of the 
mesothorax, the sulcate prosternum, &c. 
PERIDINETELLUS, gen. nov. 
Rostrum stout, curved, about as long as the prothorax, the scrobes oblique, lateral, visible from the side, the 
antenne inserted near the middle; eyes large, distant; prothorax subcylindrical, convex, bisinuate at 
the base, compressed at the sides of the disc posteriorly; scutellum strongly transverse, subquadrate ; 
elytra oblong, one-half wider than the prothorax; pygidium not visible; prosternum deeply sulcate ; 
anterior cox narrowly separated; meso- and metasternum flattened and depressed between the middle 
coxe ; ventral sutures 2-4 deep; mesothoracic epimera ascending, large ; femora sharply dentate ; tibis 
sharply unguiculate ; tarsi with joint 3 bilobed, the claws small and completely connate; body convex, 
in great part glabrous. 
This genus includes a single species, which in its general facies is very like a small 
Otidocephalus. Following Lacordaire’s arrangement, it belongs to the Peridinetides. 
The subcylindrical, posteriorly compressed, smooth prothorax, almost glabrous body, &c., 
distinguish the present genus from Peridinetus. 
1. Peridinetellus subnudus, sp.n. (Tab. XI. figg. 4, 4a.) 
Oblong-oval, very shining, glossy black ; the prothorax and elytra with a narrow, common, transverse, curved 
fascia of pure white, hair-like scales at the base, the sides of the body beneath also with a narrow band of 
similar scales—dense on the metathoracic episterna and extending forward along the propleura,—the base 
of the rostrum and the legs with scattered white scales. Head sparsely, minutely punctate, broadly and 
deeply sulcate between the eyes ; rostrum sparsely, finely punctate, smooth along the middle at the base. 
Prothorax as long as broad, scarcely narrowed in front, almost smooth, with a deep longitudinal furrow 
on the posterior portions of the flanks. Elytra somewhat triangular, the humeri obtuse but prominent ; 
very faintly striate, the strie deeper at the sides and with fine, scattered, oblong, shallow punctures, 
these becoming deeper towards the base and suture. Beneath almost smooth. Tibie and tarsi slender. 
Length 22, breadth 11 millim. (9?)
