MEMOIRS ON THE COLEOPTERA 



known at present, ruricola Oliv., and the new species described 

 below; albofasciatus is here made the type of a separate genus. 

 Clytanthus resembles Neodytus closely, differing principally in the 

 even and fine dense sculpture of the pronotum, without isolated 

 asperities or carinules, and in the dilated anterior tarsi of the males. 

 There are, however, some other peculiar crural characters, present 

 at least in our two species, the middle femora being notably stout 

 in the male and the middle tibiae bent and thickened apically, with 

 the apex lobed; these characters are also somewhat evident in the 

 female as well, but whether they are in any way general among the 

 numerous palsearctic species I am not able to state. 



Clytanthus catulus n. sp. Subparallel, the elytra almost parallel and 

 very much less tapering than in ruricola, black, the elytra feebly picescent, 

 the legs pale flavo-testaceous, the femora black, the middle and posterior 

 pale basally; antennae moderately slender, slightly thicker distally, a 

 little more than half as long as the body, pale flavate, the basal joint 

 dusky and the outer four nearly black, the seventh transitional in color; 

 second joint two-fifths as long as the third, which is longer than the 

 mutually equal first or fourth; prothorax fully as long as wide, wider at 

 the broadly arcuate apex than at base, the sides in about apical half very 

 feebly converging, rounding medially and thence straighter and con- 

 verging to the basal margin; surface convex, very densely, finely sculp- 

 tured and dull, scarcely at all pubescent, except the narrow yellow apical 

 and basal margins; scutellum transverse, rounded, densely clothed with 

 yellow pubescence; elytra wider than the prothorax and two and nearly 

 one-half times as long, obliquely truncate at the apices, the external angle 

 sharp but simple, with a transverse discal spot of dense yellowish pubes- 

 cence near the base, a straight subsutural line from basal sixth to third, 

 a medial transversely oval spot just before the middle, another smaller, 

 more anterior and near the side and, near apical fourth, an oblique fascia 

 from near the side to the suture; under surface with spots and ventral 

 annuli nearly as in ruricola. Length (cf) 8.0 mm.; width 2.2 mm.

Differs from ruricola in its smaller size, rather less elongate and 

 more slender legs, and very greatly in antennal structure, the basal 

 joint being shorter and the outer joints shorter and more compactly 

 joined, being more parallel and less narrowed basally or less oval; 

 it also differs in the disposition of the anterior elytral spots and 

 in the position of the ante-apical fascia, which in ruricola is but 

 little more than three-fifths from the base and therefore much more 

 distant from the apex than in catulus. The female in ruricola 

 seems to be very much rarer as well as smaller than the male.
