10. TIPHIA STERNODENTATA, new species 



Male. — Vertex with primary punctures of first-degree density be- 

 tween and behind ocelli and near upper orbit of eyes, sparse on either 

 side of medial patch. Front vaguely shagreened ; impunctate stripe 

 and groove well developed; primary punctures large, of first-degree 

 density upward from base of antennae to vertex laterally and to 

 lowest ocellus along stripe,, with a more sparsely punctate area 

 diagonally below triangle; secondary punctures not apparent. An- 

 tennocular distance greater than width of antennal fossa. Ciypeal 

 extension with its width four-fifths the clypeoantennal distance; 

 apex shallowly emarginate, with a narrow, impunctate border of 

 uniform width and with a thick edge. Pronotum with punctures 

 very large and shallow, uniformly of first-degree density, but with a 

 tendency to second-degree density on apical half; almost devoid of 

 secondary punctures. Side of pronotum sharply rugosopunctate be- 

 hind carina, with a tapering series of diagonal rugae across center. 

 Mesepisternum with primary punctures large and clearly outlined, 

 mostly of first-degree density; secondary punctures well differenti- 

 ated, more numerous than primaries on upper half, becoming sparse 

 and finally disappearing medially; posterior border with a linear 

 groove extending upward to spiracle. Scutellum minutely punctate 

 to impunctate, apex much wider than diameter of lowest primary 

 punctures. Metanotum with apical callosity, elsewhere densely coarse- 

 punctate, with the primary punctures covering an area equal to
