(EDEMERID.E. — NOTHUS. 59 



Genus CCCCLXII.— Nothus, Ziegler. 



Antenna ll-jointed, simple^ filifornij the basal joint robustj second very shorty 

 remainder of nearly equal length, the terminal one shortest, elongate-acumi- 

 nate, and the basal ones rather longer than the other. Palpi unequal ; 

 maxillary with the terminal joint elongate-securiform; labial with the same 

 joint transversely produced, and also securiform : mandibles entire at the 

 apex : labium deeply notched : head nutant, with a rather broad base : eyes 

 emarginate : thorax transverse-orbiculate, with the sides margined: body 

 elongate, of soft texture, nearly cylindric, narrow: coleoptera not broader 

 than the thorax : legs moderate ; femora slightly thickened : tibice simple, with 

 extremely short spurs at the apex ; tarsi with the penultimate joint bilobed : 

 male with the posterior femora considerably incrassated, concave within, 

 with an obscure tooth towards the apex, and the tibi(B of the same legs 

 stout, cuiTed, angulated at the base, and terminating at the apex within in 

 an acute spine, the apex itself with two short spurs. 



The male Nothus may be instantly recognised by its incrassated 

 posterior femora, combined with the securiform palpi, broad trans- 

 versely-ovate thorax, and linear elytra, exclusively of other charac- 

 ters ; and the female, which sex closely resembles a Conopalpus, 

 ■differs therefrom by its 11-jointed antennae, and from the other genera 

 of this family by the structure of its palpi, thorax, &c. The species 

 are found on flowers.

Nothus bimaculatus. Olivier. — Steph. Catal. 252. iVo. 2502. 



Male fuscous-black, slightly pubescent: mouth and labrum rufous: thorax 

 with the margins and a dorsal line pale rufous ; elytra transversely rugu- 

 lose, immaculate, with the lateral margins faintly rufescent : body beneath 

 rufous at the apex : legs bright rufo-testaceous, with the apex of all the 

 femora, and of the tibiae and the tarsi, fuscous-black: three basal joints of 

 the antennae rufous, the remainder black. Female with the mouth, thorax, 

 and legs rufo-testaceous, the latter palest : the head posteriorly, two small 

 spots on the thorax, and the tips of the femora, and of the tarsi and poste- 

 rior tibiae, the breast, a row of spots on each side of the abdomen, and apex 

 of the antennae black ; the base of the latter pale: elytra also pale testa- 

 ceous, with the apex, and a faint lateral streak black. 



Of this rare insect about a dozen examples have come beneath my 

 inspection ; one of these was taken near AVindsor in June, 1816, a
