32 APOGONIA IMPRESSA. 



perceptibly protruding, their lateral margin narrowly ex- 

 planate; the sides before the obtuse basal angles faintly 

 emarginate; the pronotum is confluently striated in a 

 longitudinal direction, the raised interspaces are smooth 

 and shining, the sulci provided with hair-bearing punctures. 

 The scutellum triangular with rounded tip, broadly and 

 deeply impressed or excavated at some distance from the 

 base, impunctate, the impression however with a few in- 

 distinct longitudinal wrinkles. 



The elytra at the shoulders conspicuously broader than 

 the base of the thorax, very densely punctured, the punct- 

 ures fine and of equal size all over, the costae only indi- 

 cated by their faint convexity. 



The punctures on the under surface larger and wider 

 apart, more approximate however on the sides, propygidium 

 and pygidium ; on the latter the punctures are slightly 

 larger than those on the propygidium. 



The anterior tibiae are tridentate, the upper tooth how- 

 ever is small.
