VIGETUS, gen. nov. 
Body broad, convex above. Head broad, short, deeply 
inserted in the pronotum, concave from between the region of 
the eyes, on the inner margin of which is a short distinct 
transverse ridge; anterior margin very slightly rounded; the 
lobes about equal in length, or central lobe slightly shortest ; 
eyes moderately transverse. Pronotum convex, the anterior 
lateral margins convexly rounded and moderately laminately 
produced, the lateral angles distinctly nodulose; anterior 
margin concavely excavated for the reception of the head, 
posterior margin nearly straight. Scutellum broad above, 
completely covering the abdomen, its apex distinctly concavely 
excavated in the male. Rostrum apparently reaching the 
intermediate coxe ; antenne with the second joint very short ; 
odoriferous apertures very broad and obliquely striate. 
A genus allied to Madegaschia, Montand., from which it 
differs by the much shorter head, the distinct nodulose lateral 
pronotal angles, &c.
