PTEROPHORIDJE—TRICHOPTYLUS. 397 



We have only one species. It singularly resembles those 

 of the genus Oxyptilus. It has usually been included in the 

 last — Lcioptilus — but has been separated by Lord Walsing- 

 ham, under the present name, with a number of closely 

 allied North American, and other exotic species.
