92 PAT CVI. 
By moft practical Entomologifts they have been confidered as dif- 
tinct fpecies, and they may be fuch ; but as we are unwilling to create 
confufion by extending the number of fpecies, we prefer admitting 
them as varieties under the Fabrician name Emargana.—We are more 
readily inclined to adopt this meafure, as we have always found them 
. at the fame time of the year, in the fame parts of the woods, and 
generally {porting together, which is not commenly obferved of Infects 
that are not either varieties or differ only in fex. 
They are rarely met with; our fpecimens were taken in June at 
Dartford.—T hey have been taken together at Caen- Wood, Hamp- 
ftead. 
They have not heed defcribed by Linnzeus; but were known among 
Collectors by the (now obfolete) name Excavana. 
At Fig. 5. is fhewn one of the varieties; the third is much yellower 
but marked with fimilar reticulated ftrokes, and exactly correfponds. 
in fize and form with this figure.
