names are worth retaining, even for varieties, and cer- 
tainly none of them represent geographical races. Speiser 
(1900, Ann. Mus. Civ. Genova, XL, p. 560) states that in 
typical H. maculata the ground color of the thorax is 
black, while in the var. aegyptiaca Macquart it is reddish 
brown. It remains to be shown whether the reddish and 
black forms are geographically segregated. If they occur 
together, they may well be due to the age of the speci- 
mens, or even to their state of preservation. 
I cannot regard H. fossulata Macquart as anything but 
a slight variation of H. maculata. Speiser (1904, Ann. 
Mus. Civ. Genova, XLI, p. 333) claims to have recognized 
fossulata in a specimen at the Vienna Museum, supposedly 
taken by Thorey in Surinam in 1859. This specimen dif- 
fered from typical H. maculata only in having a chestnut- 
brown (not black) thorax, the three spots of the scutum 
mesonoti not connected, and the fore and middle legs with 
only the apex of the femora and two rings of the tibise 
brownish black. These variations, however, are readily 
matched in a series of H. maculata. Macquart was uncer- 
tain about the locality of his specimen. If the specimen 
seen by Speiser actually came from Surinam, it must have 
been introduced there with cattle from the Old World.
