Because of the size of the moth subfamily Pyraustinae, the editors have decided to present it in several parts instead of one part as stated in the Preface to Fascicle 13.1A. Fascicles 13.2A and 13.2B deal with the tribe Pyraustini; Fascicle 13.3 will deal with the tribe Spilomelini, completing the treatment of the Pyraustinae.
