UNDESCRIBED INSECTS THE COLLECTION OF WILLIAM WILSON SAUNDERS, ESQ., E.RB.S., F.L.S., &c. Von:. 2. DIPTERA—By FRANCIS WALKER, F.LS. LONDON : JOHN VAN VOORST, PATERNOSTER ROW. M.DCCC.LVI. LONDON: PRINTED BY EDWARD NEWMAN, 9, Devonshire Street, Bishopsgate, PREFACE. Ix the present volume will be found characters of nearly all the undescribed species of Dipterous Insects in my collection which had been received to the end of the year 1854. Mr. F. Waker, a gentleman well known for his intimate acquaintance with this Order of Insects, has supplied the whole of the Manuscript. The Plates have been furnished by Mr. Wrstwoop, whose entomo- logical knowledge and skill in the delineation of Insects are universally admitted. To both I tender my best thanks. W. WILSON SAUNDERS.

The study of these insects is connected with that of quadrupeds, and comprises a knowledge of the distribution, introduction, diffusion, diminu- tion and extinction of the Ruminants and of some other groups. The species of Tabanus are generally local, but as a genus it extends nearly over the world, and both the reindeer and the camel are its prey. In many regions it has not as yet been observed, and consequently its geo- graphy and the relative proportion of species in the various continents and islands is comparatively unknown. Some parts of the structure are very variable in form, especially the third joint of the feelers and the tip cross-vein which divides the submarginal areolets: these variations are too numerous and too gradual to be regarded as characters of groups or of subgenera, but their succession and limits may be exhibited by a tabular series of the species, or by means of curved lines in diagrams. The third joint of the feelers in some species is slightly convex above, in others it is armed with a long horn, and no link is wanting between these two forms. The fourth and following joints form a compound joint which varies much in length, and is either straight or curved upward, stout or slender. A curve near the base of the tip cross-vein has very frequently a tendency to assume an angular form, which is very rarely a right angle, but generally more or less obtuse. It is often accompanied by the stump of a vein, which is long in proportion as the angle whence it springs is more distinct and less obtuse, or, in other words, the two veins incline more or less to be blended into one. In New Holland and New Zealand yD) INSECTA SAUNDERSIANA. there are species which unite Tabanus and Pangonia, and several kinds which have been separated from Tabanus are but aberrant, or the last links of its variations.
