Hah. — "Clarence River" {fide Castelnau), Richmond River 

 (Helms). 



The only species known with the interstices of the elytra foveo- 

 late. The synonymy given is on the authority of Chaudoir (Ann. 

 Mus. Civ. Genova, 1874, vi., p. 585).

Elliptical-oval. Head small (2*8 mm. across eyes); pro thorax 

 subcordate; sides shortly subsinuate before basal angles : elytra 

 oval, deeply crenulate-striate; third interstice 3- or 4-punctate,

Ej'es convex, rather protuberant; postocular part of orbits not 

 large, rising from head in a carve almost continuous with the 

 eyes. Labrum lightly emarginate. Apical joints of antennae 

 short. Prothorax broader than long (3-5 x 4 mm.), widest a little 

 before the middle; apex emarginate, a little wider (2-8 mm.) than 

 base (2-7 mm.); sides lightly rounded, lightly narrowed to apex, 

 decidedly narrowed in a gentle curve posteriorly, shortly sinuate 

 before basal angles (in 9 the sinuosity often obsolete); anterior

 obtuse; base emarginate in middle, curving decidedly forward on 

 each side; lateral border rather widely reflexed, hardly narrower
