Notes on Diptera Occurring in Hawaii. 
BY J. F. IELINGWORTH. 
(Presented at the meeting of February 2, 1922.) 
Comparatively little has been published on Hawaiian Diptera. 
The rather extensive investigations of Terry, while doing much 
to aid local entomologists in a knowledge of many species, was 
unfortunately cut short by his untimely death; hence, few of his 
data were ever published. 
In this paper it is my desire to submit accumulated informa- 
tion on two of our commonest flies, and also add a few remarks 
on several other species listed in the Fauna Hawaiiensis, but not 
known in collections here. Most of the matter dealing with 
terminology has come through the kindly assistance of Dr. J. M. 
Aldrich, of the United States National Museum, Dr. Guy A. K. 
Marshall, of the British Museum, and Major W. S. Patton, of 
Edinburgh University, the latter having visited the principal 
type collections of Europe during the summer. 
Synthesiomyia nudiseta (Van de Wulp), det. by Patton. 
Cyrtoneura nudiseta Wulp, Argentine Republic. 
Synthesiomyia brasiliana B. & B., Brazil. 
This American species is evidently a rather recent arrival in 
the islands. Terry did a lot of breeding work on it in 1910, and 
though I first collected it in Fiji (June, 1913), I found it abun- 
dant here as soon as I began breeding carrion flies, early in 
1914. At that time this species went under the common name 
of the red-tailed Sarcophagid, as designated by, Bridwell,t who 
had done some breeding work with the species, and discovered 
that the larvae made cocoons in sand. My Fiji specimens were 
determined by Aldrich as 5. brasiliana B. & B. and, I believe, 
Bridwell, too, so determined it, for he used this name in his 
paper,” presented before the Medical Society here. ‘
