ADSTRO-MALAYAN DIPTERA 435 



DOLIGHOPODID AE . 



Paraclius (?) praedicans Walk. (Dolichopus) J. Pr. Lin. Soc. 

 IV, 115 (Celebes)! 



One (f, two 9; 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, wdth silvery pleurae. In agreement with the opi- 

 nion 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. Ill, 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). 



Diaphorus sp. One specim. ; Dorei Hum, N. Guinea (Beccari). 



All the other Bolichopodidae of the collection belong in the 

 genus PsilopuSj, of which there are about tioenty species. More 

 than eighty species of this genus are described from the Malay 

 Archipelago and Australia. I have identified the following two 

 species : 



Psilopus aeneus (Fab.) Macq. D. E. II, 2, 116, Tab. 19, f. 3 

 (Java). 



0^9; Aru Islands, Wokan, 1873 {Beccari). 



Macquart gave a description of Fabricius's types , therefore 

 the identity is not doubtful. Those specimens were males; the 

 female has a more coppery abdomen and the black crossbands 

 are a little broader.
