HAMPSON ON THE CLASSIFICATION [Dec. 17, The Schcenobiince have become differentiated from the Pyraus-tince in the loss of the proboscis, the Crambince in the pectination of the median nervure of the hind wing, whilst the long porrect palpi and triangularly scaled maxillary palpi are highly characteristic of nearly the whole of the genera of both subfamilies. The classification of the Schcenobiince as a group is new; their habitat being principally in the Oriental and Neotropical regions, with but few genera and species in the Palsearctic region. The Crambince, however, are found in almost equal numbers in all the Zoological regions, and their classification, as here given, is an extension of the excellent system adopted by Mr. Meyrick in his paper on the Pyralidse of the European fauna. The types of all the new species described are in the Collection of the British Museum, and I have to thank Mr. W . Schaus for the generous gift of examples of all the species, from the Neotropical region, of which he had more than one specimen in his collection, for purposes of description in this paper. I have also to thank Mr. Meyrick for the loan of many Australian and N e w Zealand species which were not in the collection of the British Museum, and Mr. Bethune-Baker for the loan of many Palaearctic species. I have included the well-known European species without references and synonymy, which can easily be found in Staudinger's catalogue and other works, but full references are given to extra-Palsearctic species. Species of which I have examined specimens, but which are not represented in the British Museum collection, are marked with an asterisk • species of which I have not been able to see specimens and of which the classification is uncertain are placed at the end of each genus; and described species of which the types are in the Museum are marked thus (f); whilst at the end of the paper will be found a list giving the families to which species wrongly described as Crambince should be referred. Subfamily SCHGENOBIIN^. Proboscis absent or very minute ; palpi usually porrect, the maxillary palpi being usually well developed and dilated with scales at extremity. Fore wing with vein 7 usually from cell. Hind wing with the median nervure not pectinated on upperside; vein 7 usually anastomosing with 8. The larvae of the species of which the early stages are known feed in the interior of reeds or on aquatic plants. The absence of the proboscis, combined with the non-pectination of the median nervure of the hind wing, will distinguish the genera of this subfamily from all other Pyralidae, except Aglossa, Crocalia, and a few other genera of the Pyralinse, from which those forms that have vein 7 of the fore wing stalked with 8, 9 are easily distinguished by vein 7 of the hind wings anastomosing with 8. |
