or setulae which are rarely white; mesonotum usually with 
black pubescence; third vein usually setulose, at least as far 
as anterior cross vein. It includes the nearctic genera Acidia, 
Strauzia, Trypeta=(Spilographa), Zonosema, Rhagoletis, 
Oedaspis, Peronyma, Epochra and Aciura. 
The tribe Myioptininae is not represented in this zone. The 
tribe Trypaneininae is characterized by having the cilia of the 
posterior orbits composed of thickened, whitish, blunted bris- 
tles or setulae ; mesonotum with whitish pubescence; third vein 
bare; proboscis usually long and geniculated. It includes the 
nearctic genera Stenopa, Terellia, Tomoplagia=(Plagivtoma), 
Neaspilota, Eutreta, Paracantha, Ensina, Euaresta, Tephritis 
and Trupanea. 
This classification is certainly an improvement over the one 
now used, proposed by Loew, and divides the family into 
groups which are probably more natural. It was character- 
istic of Loew to disregard the chaetotaxy, so he had to fall 
back on the wing pattern in most cases. In the study of this 
paper of Prof. Bezzi’s and of a few others, augmented by a 
small collection, a few interesting problems have come up, 
dealing mainly with nomenclature, which have given rise to 
the following notes: 
Trypeta Meig. (Spilographa Lw.). 
Trypeta was first proposed by Meigen in 1803' for the species 
Musca arnica, M. cerasi, M. urticae, M. artemisiae. All are 
credited to Fabricius. Curiously enough, none of these species 
was included in the genus by Lrew in his Bohrfliegen, 1862, or 
has been since. The type species was first designated by Coquil- 
lett in 19107 as Musca artemisiae Fab. (1794). This species 
was one of those originally included under Spilographa Lw. 
(1862) so this designation makes the latter genus a synonym of 
Trypeta. This unfortunately causes some confusion in the con- 
ception of the two, but there is no other solution unless the 
other species originally included under Spilographa are not con- 
generic. The species heretofore known as typical Trypetae will
