By most practical Entomologists they have been considered as dis-tinct species, and they may be such ; but as we are unwilling to createconfusion by extending the number of species, we prefer admittingthem as varieties under the Fabrician name Emargana.—We are morereadily inclined to adopt this measure, as we have always found themat the fame time of the year, in the fame parts of the woods, andgenerally sporting together, which is not commonly observed of Insectsthat are not either varieties or differ only in sex.

They are rarely met with j our specimens were taken in June atDartford. —They have been taken together at Caen-Wood, Hamp-stead.

They have not been described by Linnæus ; but were known amongCollectors by the (now obsolete) name Excavana.

At Fig. 5. is shewn one of the varieties; the third is much yellowerbut marked with similar reticulated strokes, and exactly correspondsin size and form with this figure.
