Antennae reddish yellow with club brownish black, 

 inserted at about the basal third of rostrum. Funiculus 

 six-jointed, short, with 1st joint twice as long as broad, 

 1^ times as long and twice as broad as 2nd joint, which 

 is twice as long as broad; 3rd to 6th joints conical (by 

 O. flagelliim they are globular), almost as long as broad 

 and of equal length. Club oval, half as long as the 

 funiculus, with hairs, circularly arranged as in the 2nd to 

 6th joints of the funiculus. 



Thorax not fully twice as broad as long, coarsely and 

 rather densely punctured, sometimes with a feeble long- 

 itudinal furrow in the middle, the extention of which is 

 most varying, reaching by some specimens somewhat 

 beyond the middle of the thorax and being sometimes 

 reduced to a short depression behind. 



Elytra broadly ovate, only feebly arched, at the shoul- 

 ders, which are distinctly prominent, broader than the 

 thorax, broadest behind middle, thense rather shortly tape- 

 ring, length as compared with width is 4 to 3. Each of 

 the elytra with Q striae, which are deep and with rather 

 strong and large punctures; striae almost as broad as the 

 interstices, latter strongly arched. 7th and 8th striae ab- 

 breviated at base making the shoulders appear larger and 

 almost smooth; Qth stria not abbreviated at base, sur- 

 mounting at base of the elytra a 10th stria, which is ab- 

 breviated behind, extending through about one fourth .of 

 the length of the elytra. 



Tibiae and tarsi reddish brown; posterior femorae 

 generally quite black, sometimes feebly reddish brown 

 towards apex and base; anterior and intermediate femorae 

 with a dark transversal fascia, varying in extention, or 

 entirely reddish yellow. Length 1,8 mm. 



In his description of O. flagellum (in Verh. d. k. k. 

 zool. bot. üesellsch. in Wien, 1Q02, pag. 15) Ericsson 

 states amongst others 1) that head is yellow-brown, rostrum 

 deep yellow, elytra dirty-yellow with darker apex and
