Enquiries are frequently made through the Entomological Research Committee with reference to TINEINA bred from cotton, and as the notes on Gelechia gossypiella, Sndrs., published by Lord Walsingham in Fauna Hawaiiensis [1. 731–4 (1907)] are not generally accessible, I have been requested to revise these notes and reprint them with additional information on gossypiella and two species of Pyroderces. It is quite clear that the Gelechia does immense damage to the cotton, attacking the seeds in the boll, but what damage (if any) is actually occasioned by Pyroderces simplex, Wlsm. (= gossypiella, Wlsm.), and rileyi, Wlsm., is not manifest; it would seem that these species are associated with cotton already injured by damp or other insects rather than themselves being the cause of injury. Further information will doubtless be supplied now that the names are available.
