Speci7nens Examined. — The total number of specimens listed 

 in the present paper is 333, of which 206 examples are in the 

 Philadelphia collections. We wish to express our hearty thanks 

 to Mr. Wm. T. Davis and to the curators of the collections of the 

 United States National Museum, American Museum of Natural 

 History, Museum of Comparative Zoology and Brooklyn Insti- 

 tute of Arts and Sciences, for the privilege of studying all of the 

 material in those collections referable to the present genus." We 

 have been unable to examine the types of the four previously 

 described species, but we have had before us series of topotypic 

 specimens of each of these, which agree fully with the original 

 descriptions. 



11 The material from Porto Rico, excepting those specimens from the Na- 

 tional Museum, was secured in connection with the New York Academy- 

 Porto Ri('0 Survey. The first set of this material is in cverj^ case the property 

 of the American Museum of Natural History.
