The caufe of this uncertainty may be partly attributed to our entire 
ignorance of their manner of life or transformations. Some of the 
Mutille have wings, and others are without. Authors have con- 
fidered the apterous Infeéts as the females, and the winged kind as 
the males, which opinion is countenanced by numberlefs inftances in 
almoft every clafs of Infeéts. Others have however maintained 
that both males and females were winged, and that the apterous In- 
fe@ts were neuters, prefuming in fupport of fuch opinion, that the 
Mutillz lived in focieties like the Wafps, Ants, and Bees.—From 
obfervations on a number of exotic fpecies of this tribe, we have 
no doubt that the winged Infects are males, and the apterous kind 
females, 
Yeats alludes to three fpecies of Mutilla that have been found in 
England, but names only the Mutilla Europea; and this is the 
only kind we have ever found. We have taken it on a fandy path- 
way, near the entrance of Coombe Wood, SUITY.
