 the head and prothorax, the tenth joint longer than wide. Pro-

 sparsely tuberculose, widest at apical fourth. Elytra convex, 

 oval, two-thirds longer than wide, one-half wider than the pro-

8. A. areiiarius n. sp. — Stout, convex, pale luteous throughout, except 

 the abdomen, which Is clouded with blackish; head and pronotum slightly 

 shining, finely reticulate, the elytra dull and strongly, more granularly retic-

 very angulate, rounded ; eyes large, convex, at much less than their own 

 length from the base and not much less prominent than the tempora; surface 

 rather finely, sparsely tuberculose, with an entire median impunctate line; 

 antennae long, slender, distinctly incrassate and slightly infuscate toward 

 apex, two-thirds longer than the head, the tenth joint not quite as long as 

 wide. Prothora.i: just visibly wider than the head and but slightly transverse, 

 widest very near the apex, the sides thence jiast visibly convergent and slightly 

 arcuate to the middle, there becoming more rounded and sti'ongly convergent
