( 19 ) IV. On the Lepidoptera of the Amazons, collected hy Dr. James W. H. Trail, durincj the years 1873 to 1875. By Arthur Gardiner Butler, F.L.S., F.Z.S., &c. [Read February 5th, 1879.] Part III.— NOCTUITES. Dr. Trail obtained 149 species of Noctuites during his expedition i;p the Amazons, but four of these were not in a sufficiently perfect condition for identification ; so that the number may be reckoned as 145, of these species no less than 55 are forms new to science. Owing to the recklessness Avith which some authors have characterized genera in this tribe, I have been saved the necessity of describing any ; but, at the same time, this recklessness has caused so much confusion in the identification and location of species, that hardly a genus of the New World Noctuites exists which does not need more or less rcAasion.
