external margin. The hind breast, part of the mid breast, 

 and a row of five spots on each side of the abdomen black : 

 the legs and the remainder of the underside yellowish. 



This species varies as to the size of the spots on the elytra. 

 In one of three specimens before me the innermost spot of the 

 middle pair is almost entirely obliterated, while the outer 

 elongated spot is broken up into two. The sides of the elytra 

 in this species attain a greater lateral extension than in any 

 species of the genus at present known to me. In this respect 

 it is most nearly approached by 0. maculata, Oliv.

Hah. New South Wales. 



Head and prothorax testaceous, finely punctulate, the 

 former black above, with a small testaceous spot on the middle 

 of the occiput. The prothorax about twice as broad as long, 

 sides diverging from the base to about the anterior third, 

 thence slightly converging to the apex; anterior margin very 

 feebly concave, almost directly transverse ; upper surface with 

 two irregular black spots, one on each side. Scutellum 

 broad, triangular, rounded behind. Elytra very finely and 

 rather thickly punctured; black, each almost completely 

 surrounded by a narrow testaceous yellow border ; epipleura 

 slightly concave, closely approximated to the external mar- 

 gin, gradually cut away behind without reaching to the 

 middle. Body underneath brownish black, with the pro- and 

 mesosterna and the tip of the abdomen testaceous. Femora 

 and bases of the tibise testaceous, rest of the legs brownish 

 black. The first two joints of the antennse testaceous (the 

 remaining joints are wanting). 



This species may be recognized by the form of the elytra, 

 which is somewhat ovate, narrower at the base than towards 

 the extremity. The apices are singly instead of conjointly 

 rounded.
