5. Apical margin of sixth visible abdominal sternite more or less produced at 



middle, the projection usually seated in a broad and very shallow 



emargination 6. 



Apical margin of sixth sternite broadly, deeply and evenly emarginate, not 

 at all produced on median line 11. 



6. Pygidium bicallose, the callosities separated more or less completely by a 



median longitudinal groove 7. 



Pygidium not bicallose 8. 



7. Callosities of pygidium well separated, the median longitudinal groove pass- 



ing between them and very nearly attaining the basal margin 



lafipes Bates. 



Callosities approximate, coalescing above, the median longitudinal groove 



short, not passing completely between them dissimilis n. sp. 



8. Pygidium with a single median callosity near base, the remaining portion 



shallowly concave, floor of the concavity with a pronounced median groove 



coUmana Arrow. 



Pygidium broadly, shallowly, and transversely excavate in apical half, the 



floor of the excavation not grooved 9. 



9. Pygidium subacutely angulate at apex, with a single low median callosity 



on the upper margin of the subapical excavation; pronotum unicolorous 



vexata Horn. 



Pygidium broadly rounded at apex, without a callosity on the basal portion 



above the excavation; pronotum bicolored as in the male sex 10. 



10. Pronotum strongly narrowed basally, as wide across anterior angles as 



across base; pygidium moderately coarsely and very sparsely punctured 



pananiana n. sp. 

 Pronotum not strongly narrowed basally, width across anterior angles much 

 less than across base ; pygidium coarsely and rather densely punctured 



personata n. sp. 



11. Pygidium subapically with a large hemispherical cavity which is bounded 



laterobasally by two low and poorly defined callosities and apically by a 



sharp protruding margin tiimulosa Bates. 



Pygidium virtually simple, without modification other than a shallow and 

 inconspicuous median impression near apex aequata Bates. 



Note : The female of ciliatipes Blanchard is known to the writer only by 

 description. The female of scabripyga Bates is unknown to him.
