I found this species very localized in Australia, apparently 
occurring only around Brisbane. After my return to Honolulu, 
I sent specimens to Patton, who found that this was Van der 
Wulp’s species nudiseta, originally described from Argentine 
Republic, in 1883.3 He placed it in Macquart’s genus Cyrto- 
neura,* which was characterized by having the antennal bristle 
thickly feathered. However, in 1893, Brauer and Bergenstam, 
securing specimens from Brazil, named the species brasiliana 
and were compelled to create the new genus Synthesiomyia® for 
it. Other localities on record for it are Florida and Georgia.® 7 
At a previous meeting I called attention to the very peculiar 
manner in which the maggots congregate so compactly side by 
side, that a cross-section of the mass of hair and dirt from the 
carcass, in which they are imbedded, gives the appearance of 
old honeycomb. 
In breeding out these flies on a dead rat, I found that the 
maggots were considerably slower in getting started than either 
those of Sarcophaga fuscicauda Bott. or Chrysomyia mega- 
cephala (Fab.); being more closely associated, when ready to 
pupate, with the larvae of Ophyra nigra Wied. These two latter 
species both have smooth shiny maggots, but those of S. nudi- 
seta have conspicuous black caudal spiracles, whereas those of 
O. nigra are brown in color, making them easy to separate.
