those on the prothorax into various spots and streaks, and those on the elytra 

 mainly into three irrejjular ang-iilated fasciae (the median one enclosing several 

 small pallid spots and extending to the outer margin, but not reaching the suture) 

 and an angular apical patch ; the eyes bhick, the antennal joints 1-4, legs (the 

 infuscate outer portion of the posterior femora excepted), and under surface 

 testaceous; densely, very finely, the prothorax minutely pui'.ctate. Head 

 small, bifoveate between the eyes ; antennae moderately long, rather slender, 

 joint 3 small, short, narrower than 2. Prothorax very short, obliquely narrowed 

 from the base, the anterior angles hharp and prominent. Elytra rounded and 

 explauate laterally, somewhat acuminate at the tip, with a faint sutural stria. 

 Posterior coxae without definite plate. Posterior legs long, the femora very 

 stout, the tibiae curved, the upper spur a little shorter than the fir.'^t 

 tarsal joint. 



Length 3, breadth 2 mm.

Two examples, assumed to be sexes, the supposed 6 having stouter 

 antennae than the other. Near O. mixta and O. marmoraia Champ., 

 the sharply defined elytral markings veiy similar to those of the Eastern 

 O. nigrojpunctata Motsch. { = irregularis Waterh.), an insect extremely 

 like the present species, except that it has the elytra uneven and with a 

 double system of puncturing.
