Miss G. Ricardo — A Revision of 



The following species are from Celebes : — 



L. dioctroides, a very small species witli a very narrow face, bearing a 

 general resemblance to a Lepfoffaater species ; Dr. Hermann places it 

 in Cenochromyia, but incorrectly, the fourth posterior cell being 

 open. 



L. partita appears to be a species of Maira. 



Laphria disciplena, from New Guinea, is very probably the same as 

 Laphrta dori/ca, Boisduval, Voyage de ' I'Astrolabe,' Entom. ii. p. 662, 

 pi. xii. fig. 10 [Dasi/pof/on'] (1835), seen by me in the British Museum. 

 The thorax is covered with bright fulvous tomentum; the antennae, 

 face, beard, and legs are the same colour ; on the sides of thorax and 

 breast a brown median stripe a])pears. Abdomen dull brownish 

 red. Winps brown, with white streaks — one at apex, another be- 

 tween the first and second posterior cells, and smaller ones in the 

 cells. Laphria concludens, Wlk., from Celebes, appears very nearly 

 related, if not identical. 



PoGONosoMA, Rondani. 

 Rond. Dipt. Ital. Prodr. i. p. 160 (1856). 



No species are known from Australia itself. Two are 

 recorded from Amboyna and Batjan I. by Dolescball and 

 V. d. Wulp. 



The genus is easily recognized by the presence of three 

 cubital cells. 



A SIZING. 



The genera as yet recorded from Australia, Tasmania, and 

 New Zealand are : — 



Asilus, L. ; Ommatius, Wied. ; Blepharotes, Westwood ;

 distus, Neoitamus, Loew ; Glaphyropyga, Schiner ; Dysma- 

 chus, Wlk. ; Heligmoneura, Bigot ; Neoaratus, Ricardo 

 (Aratus, Wulp); and Pararatus, gen. nov.
