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, 

 Strauda, Trypeta= -(Spilographa), Zonosema, Rhagoletis, 

 Oe das pis, Peronyma, Epochra and A dura. 



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, Tomopla>gia=(Plagiotoma), 

 Neaspilota, Hutreta, Paracantha, Ensina, Euaresta, Tepliritis 

 and Trnpanea. 



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.). 



Trypcta was first proposed by Meigen in ISO3 1 for the species 

 Musca arnica, M. cerasi, M. urticae, M. arte-misiae. All are 

 credited to Fabricius. Curiously enough, none of these species 

 was included in the genus by Loew in his Bohrfliegen, 1862, or 

 has been since. The type species was first designated by Coquil- 

 lett in iQio 2 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
