sides parallel to near apex, apex feebly produced and rounded. 

 Pectoral canal not very deep or wide, terminated nearer anterior 

 than intermediate coxye, in front acutely margined, each margin 

 just behind the ocular lobe produced in a tooth-like process. 

 Mesosternal p^-ocetss level with metasternuni, flat except that it is 

 slightly scooped out in front, the sides being produced forwards 

 so as to touch the anterior coxae. Metasternum large, the length 

 of basal segment of abdomen ; episterna large. Abdomen large,, 

 sutures distinct; basal segment longer than 2nd, apex incurved 

 to middle, intercoxal process rather narrow and rounded ; inter- 

 mediates slightly sloping from apex to base, their combined 

 length equal to that of 2nd and slightly more than that of apical. 

 Legs moderately long and thin; femora edentate, narrowlj' and 

 very feebly grooved for half their length, posterior terminated 

 before apex of abdomen ; posterior coxae transverse, almost 

 touching elytra ; tibia:* thin, compressed, grooved, bisinuate 

 beneath, each in addition to the terminal hook with a small sub- 

 apical tooth both above and below; tarsi moderately narrow^ 

 3rd joint not much wider than long, deeply bilobed; claw-joint 

 elongate; claws strongly curved. Cylindrical, squamose, punctate, 

 winged. 



Of the described Australian genera this is the only one in which 

 the scape does not extend to the eye; and there is no scrobe behind, 

 the rostrum in its position being flattened and shining back to 

 the eye ; in front, however, there is a groove so that the side 

 appears somewhat as a boar's tusk. The dilated 2nd joint of the 

 f unicle reminds one somewhat of the antennae in many of the 

 I'selaphuhe. As Mr. Pascoe has remarked, it is allied to the New 

 Zealand Oreda, which has the teeth-like projections of the mar- 

 gins of the pectoral canal more acute and longer than in Z. 

 sferculioi /...this character is a most remarkable one and it is 

 singular that it should have been overlooked by Mr. Pascoe; does 

 it denote an approach to such forms as Chirozetes and Mecopus ? 

 Oreda agrees in many unusual features with Zeneudes, but is 

 separated on account of the mesosternal receptacle being cavernous 

 and the scape extending back to the eye.
