Material is routinely sent for identification to willing specialists and loaned for research to students and established specialists. Presently large numbers of specimens are on loan in the families Corydalidae, Mantispidae and Berothidae. The Brackenridge Field Laboratory Collection has some 355 specimens representing 12 families. The majority of this material is unidentified. This collection is particularly strong in the Myrmeleontidae, Mantispidae, Chrysopidae and Ascalaphidae.
Geographic representation is predominantly from Texas, but other areas also are represented.
In the March 1994 issue we mentioned that Carpenter's 1936 revision of Nearctic Raphidioptera is still the only key available to North American snakeflies. Unfortunately, we missed the recent world monographic revision of the Raphidioptera, which includes keys to North American species. We apologize for this oversight and error. U. Asp ck, and H.
