Head small, not concealed by prothorax. Eyes large, widely 

 separated above, almost touching beneath, facets moderately large. 

 Rostrum lung, thin, feebly curved. Antennoi moderately stout; 

 scape inserted slightly nearer apex than base of rostrum; two basal 

 joints of funicle moderately long, the others strongly transverse; 

 club elongate, continuous with funicle. Prothorax narrowed and 

 produced in front, constriction slight, ocular lobes prominent. 

 ScuteUum suboblong, very distinct. Elytra long, base widely and 

 semicircularly emarginate. Pectoral canal narrow, deep, termi- 

 nated at base of anterior coxae. Prosternal receptacle raised, 

 triangular, walls thin, rounded behind, cavernous. Intercoxal 

 process of mesosternum subtruncate at apex. Metasternum 

 elongate, episterna longer than three basal segments of abdomen. 

 Abdominal segments large, sutures distinct; first about once and 

 one-half the length of second; second, third and fifth subequal, 

 slightly longer than fourth. Legs long; coxae large, the inter- 

 mediate separated less widely than the anterior; femora peduncu- 

 late, dentate, posterior passing elytra; tibiae short, subfalcate. 

 Elongate, subcylindrical, squamose, punctate, winged. 



Perhaps the most remarkable genus in the subfamily. The 

 receptacle for the rostrum forms part of the prothorax, not as 

 in almost all the other Australian genera — of the mesothorax; it 

 appears as if forming part of an additional segment, the suture of 

 which is distinct at the sides and is even traceable across the 

 base of the pronotum. The eyes are almost as in Tranes. The 

 abdomen appears to be comfiosed of six segments, the fifth being 

 widely emarginate and allowing the apical dorsal segment to be 

 seen; this segment is doubled over and squamose, and might
