details with which I had illustrated the figure in question (published from my

The third species has been unnoticed by entomologists; and it is to the 
liberality of W. W. Saunders, Esq., F.L.S., &c. (by whom it was captured in 
India,) that I am indebted for my specimen, which was the only one in his 
collection. When first examined the wings were matted upon the abdomen, 
and the insect had all the appearance of a small earwig: this similarity is not 
merely external, since the structure of the mouth is nearly identical.
