No species have been recorded in this genus from the 

 Australian Region with the exception of three species from 

 Celebes^ viz. : — 



Allocotosia aurata, Fabr., scitula, Wlk., and vulpina, Bigot ; 

 the Walker species has also been recorded by Schiner from 

 Amboyua. 



Emphysomera, Schiner. 



Verb, zool.-bot. Ges, Wien, xvi. p. 845 (1866). 



The only species as yet recorded from the Australasian 

 Region are E. nigra, Schiner, Novara Reise, Dipt. p. 195 

 (1868), from Gilolo ; E. peregr'ina, v. d. Wulp, Tijd. v. 

 Entom. (2) vii. (xv.) p. 253 (1872), from Ternate ; and 

 E. spathuluta, DoL, Nat. Tijd. Nederl. Ind. (4) iii. xvii.

Walker's species Ommatius platymelas is the same as 

 E. spathulata. Ommatius invehens and bacchoides, Walker, 

 both belong to this genus from I. VVaigiou and Ceraiu ; the 

 latter type, a male, has the wing dilated on fore border as in 

 E. peregi'ina. 



The genus is easily distinguished by the flat face and 

 club-shaped abdomen.
