The ASOPINAE contains two well known species of Australian bugs: _Cermatulus nasalis_ is common on the Richmond and Tweed Rivers, N.S.W. It measures slightly over ½ an inch in length, and has a somewhat rounded form, with a small projecting head. Specimens vary from an olive brown to almost black colour, and are mottled with deep red; the upper surface is deeply and closely punctured, and the tips of the elytra are metallic bronze. The Vine-moth Bug, _Oechalia schellembergi_, is one of our most interesting species from an economic point of view because it preys upon the caterpillar of the vine moth (_Phalaenides glycine_), several species of cut-worm, and the larvae of the fig-leaf beetle (_Galeruca semipullata_). They lay their rounded glassy eggs in patches of about a dozen upon the foliage, and the freshly emerged bug is dark brown, and flattened in form. The adult bug varies very much in size; the largest is about ½ an inch in length; it is very finely punctured, and is of a general light reddish brown colour mottled with yellow; the sides of the thorax are stoutly spined, and the abdomen is rather tapering toward the tip. It has a wide range over Australia, and is recorded from New Zealand. The Spined Orange Bug, _Biprorulus bibax_, is a well known orange pest about Moree and the Tweed and Richmond Rivers, N.S.W. It is a handsome bright green bug when alive, but after death usually changes to dull yellow; it measures nearly an inch in length and ¾ of an inch across from tip to tip of the large thoracic spines; the front of the thorax between these stout spines is somewhat depressed; the abdomen is broad and rounded, and the dorsal surface finely punctured.
