I have vindicated the naino of l'urjtlii/roj)n for this jjeiius in the tifth volume of the Nrue Heitriige. An entirely unfounded opposition had been raised against it. The following are the reasons by whieh I hnvc been governed with relation to the luime rorpliifropn. Mcigcn, in the fourth volume of his works, luis taken a wider view of tho genus Porphynqui ami divided it into three sections: 1. With a subaj)ical arista. 2. With an apical arista; and, J], With an arista inserted dorsally on the third joint, near the basis. In his seventh volume he ado])ts the genus Arrjiira, which M. Mac(|uart had in the meantime established for the first of the three divisions ; the third division he unites with Mcdeh'ru>i; and for the oidy renniiinng second division, which j)rinci]>ally contains sMccies of the present genus, he retains the mime of P(»r])h!/ro}»- ; at the same time he uintes with them the species of his genus Ithnphium (that is the genera lihajihium and XipJiandniim in the sense adopted above). As I cannot Jigree with this reunion, I am com- pelled to retain the name of /'orphi/rops for the genus, which embraces most of the species contained in Meigen's second division and this is the present genus. The name Porphi/rops (from jtoptviio. scarlet, and w^, fa<'e) lias reference to the beautiful scarlet color which is peculiar to the eyes of ma
