If we ])egin with Orlaliti lamed {pulchella Meig.), we are led at once towards Sciomy^a bucephala Meig., wiiich Mac(piart has united, with several other het(!rogeneuus species, in the genus Oiih's, and for which I have later celablished the genus Curniocaris. Cormncoris brings us to Tvtariopii, which agrees in its prin- cii>al characters with t'onnocaris huccjihala, quite erroneously placed in the genus Sviomyza \)y !Meigen. In this species, as well as in all the European species of 2\'la)w/is which I know of, none of the characters are wanting the presence of which distinguishes the genus Or/olis. 'Hh' geiuis Titanoim again leads us towards Doryccra; the remarkable elongation of the second antennal joint is a peculiar character of most species of this genus, a character not to be found in the species of Ortalis. However, the difl'erence in the length of this joint in difTerent species of Dori/cera sufTicieiitly shows that too much .ystematic stress ought not to be laid upon this 'ter; all the other characters agreeing with those of the Ortalidiv, JJorijcera must necessarily be placed in this family. to Dfii'yara I find the genus Adapsilia, founded by Waga, which, like most Thirticrrir, has an elongated second an- tennal joint. It is distinguished by a very projecting front, very approximated antennaj, and the want of ocelli ; with the species of Ortalis it agrees in the characters already spec
