For the generous loan of type specimens, the author is deeply 

 obligated to the following individuals and the institutions they

 mens with Signoret types; to Dr. W. China of the British Museum

 Argentine museums; to Dr. H. Ruckes, New York, N. Y., for notes 

 and sketches of his types in the American Museum of Natural History;
