This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1881 edition. Excerpt: ... DOLICHOPODID AE. Paraclius (?) praedicans Walk. (Dolichopus) J. Pr. Lin. Soc. IV, 115 (Celebes)! One o7," two $; Kandari, Celebes, April 1874 (Beccari). M. Walker's statement: cinereous, not metallic is based upon the fact that his type-specimen was dirty. The thorax is metallic-green, with silvery pleurae. In agreement with the opinion of my friend Prof. Mik, whom I consulted on the subject, I place this species in the genus Paraclius Loew, to which it is undoubtedly more related than to any other. Only the last section of the fourth vein is nearly straight, and by no means as much arcuate as in the N. American species of that genus (hitherto the only ones known; comp. Loew, Monogr. N. Am. Dipt. II, p. 97-100, Tab. IIl, f. 7); the angle it forms is much more rounded; the third antennal joint is not rounded at tip (more like 1. c. fig. 8 c). Oiaphorus sp. One specim.; Dorei Hum, N. Guinea (Beccari). All the other Dolichopodidae of the collection belong in the genus Psilopus, of which there are about twenty species. More than eighty species of this genus are described from the Malay Archipelago and Australia. 1 have identified the following two species: Psilopus aeneus (Fab.) Macq. D. E. II, 2, 116, Tab. 19, f. 3 (Java).
