I have lately had on opportunity of examining bred specimens of the European Ochria ochracea(flavago). The clypeal tubercle may be felt with a fine pin or seen under the glass when the frontal scales are partly removed. We have two North American species agreeing with Ochria, viz., Sanzalitae, from California, and Buffaleonsis, from the east. With the former, the European species has a nearer resemblane externally; our eastern species differing much in colour.
