. Synonyyny. — A very variable group of Bombylids, in- 

 cluding a variety with sulphur-coloured hair, and another 

 with deep red hair, appears to form a species to which the 

 above descriptions agree; it is possible, however, that some 

 of these descriptions will ultimately be found to belong to 

 Sisyromyia decoratus. Walker, or an allied species. 



Sisyromyia decoratus. Walker. 

 Bombylius decoratus. Walker, List Dipt., B.M., ii., 1849, 



p. 291. 

 Note. — This species was described from Western Aus- 

 tralia, but a specimen identified by White is in Dr. Fergu- 

 son's collection, and was taken in New South Wales. The 

 specimen does not agree very well with Walker's description, 

 but nevertheless it is retained in this posiMon until it can 

 be compared with the Western Australian form. The anterior 

 border of the wing is fuscous, and is sharply defined from 

 the hyaline area of the wing, whilst in S. auratus. Walker, 

 the darker area on the anterior border of the wing 

 is suff'used.
