 omnibus fere MelobesiaB speciebus nunc concentrice striala, nunc omnino 

 estriata observatur. Depressionem keramidiorum astati esse adscribendom, 

 nobis persuasum est; ex nostris enim speciminibus nonnulla habent ke- 

 ramidia depressa nullo adhuc poro pertusa, alia vero keramidia hemis- 

 phaerica, poro pertusa. Ilia relate juniora, ha?c vero provectiora.
