Título en español

The purpose of "Insectae Portoricensis" was to give the records of all the insects (economic or otherwise, but especially and in considerable detail the notes concerning those of economic importance) from the  Island then officially called Porto Rico (which includes Culebra, Vieques and minor islands on the east, and Desecheo and Mona Islands on the west); up to shortly before the date of publication, March 1924. Five months later a supplement was issued, to give the determinations received too late for inclusion in the original annotated list. "Insectae Borinquenses," issued as the January 1936 number of the Journal of Agriculture of the University of Puerto Rico, but actually not published until July tenth of that year, was intended as a record of all determinations up to the end of June 1935, for the same Island, now officially known as Puerto Rico. In the present supplement, references to these original lists are abbreviated to "IP" and "IB" with a dash followed by the page number. The MS was submitted for publication on July 1, 1940, and is intended to cover all records up to that date. Several important publications received shortly afterwards are, however, noted [in brackets] in the bibliography, although the additional records and numerous changes in the synonymy have not been made in the list of insects itself.
