the Islands. Hence, here, as well as elsewhere, it has gone 
under a variety of names. Van Dine got it determined in the 
United States National Museum, in 1907, as Calliphora dur 
(Esch.), and, in 1909, Terry determined it as Lucila dux 
(Esch.). Early in 1916, Swezey sent specimens to the United 
States National Museum, and these were determined by Knab 
as Chrysomyia dux (Esch.). Now, Patton has compared our 
specimens with the type and cleared up the synonymy. In his 
letter of September 10, 1922, he says: “I went to Kiel and 
found that the whole of Fabricius’ collection of Diptera was 
destroyed, only pins left. Fortunately his type of megacephala 
was not completely gone and I was able to recognize it. At the 
back of the label were the words ‘Ex. Ind. Or.’ This finally 
disposes of this species. The type came from India and not 
from West Africa. Ch. flaviceps Macq. is the same species, as 
is also Wusca dux Esch.” 
The distribution of this species is extremely wide, extending 
from India, probably its native home, to Hawaii. Muir collected 
it in China, Borneo, and Java, and Fullaway took specimens in 
Guam, Eschscholtz’s type locality. It is also found in New 
Hebrides and Australia. I saw a male specimen taken near 
Sydney, in the Australian Museum, and a male has just been 
forwarded in a collection from New Hebrides. 
It breeds in all kinds of animal matter, and has been recorded 
repeatedly as a sheep-maggot fly in Hawaii. The adults are 
particularly fond of sweets, and are frequently found in swarms 
in fields of corn affected by leaf-hoppers, where they feed 
upon the honey dew. 
Lucilia caesar Linn. 
This widespread carrion species probably does not occur in 
Hawaii. The basis for including it in our fauna has been How- 
ard’s record * of three specimens collected by Henshaw, on the 
island of Hawaii. No one has collected caesar here subsequently, 
so I asked Dr. Aldrich to try to locate these specimens in the 
United States National Museum collection and clear the matter 
up. May 20, 1922, he wrote: “I find no Hawaiian specimens 
under this species in the collection, but there are three speci- 
mens collected by Henshaw, April 16, 1900, correctly placed 
under Lucilia sericata. Inasmuch as Howard did not mention
