PRINTE j 7 ‘ 9, D “ i + i »* © ~ 1 " ‘ . : , Pas i } Pet ‘ “Hy INTRODUCTION. THE principal object of the present Catalogue has been to give a complete list of the specimens of Dipterous Insects contained in the collection of the British Museum, indicat- ing at the same time the peculiarities of each, as regards variations of character, locality, and the source from whence it has been derived. With this view, the different individuals of each species contained in the collection are indicated by _ the letters a, b, c, &c., following the name of the species and its synonymes, and the description, if it appeared to have _ been before undescribed. This part of the Catalogue of Dipterous Insects has been prepared and the new species described, by Mr. Francis WALKER, so well known for his attention to this order of Insects. The remaining parts, containing the other families, are in hand, and will follow as soon as they can be completed. JOHN EDWARD GRAY.
