ADOTELA. 
The insects on which this new genus is formed, have en- | 
tirely the form and characters of Parroa, with the exception 
of the palpi, which are all terminated by a large triangular — 
article, having the form of a hatchet; the last of the labial 
is still larger, and more securiform than the one of the max- 
illary. The three first articles of the anterior tarsi have ’ 
below small spongious brushes.
