locality at which the specimen figured was taken is given in the 

 explanation of the plate, and each specimen so utilized bears the 

 label " drawn" in Mr. Scudder's handwriting. It is practically 

 certain that these are the specimens which Mr. Scudder would have 

 chosen as the single types of his new species had such action at that 

 time been customary. 



Practically every specimen of the group used in the preparation 

 of this work was labelled " Scudder's Type," consequently such a 

 label signifies solely that the specimen, if belonging to a species there 

 described as new, belonged to the typical series. 



In Mr. Scudder's paper the collection to which the material belongs 

 is given in parentheses after each reference, but where no parentheses 

 are to be found it is understood that the material belonged to Mr. 

 Scudder himself. 



All but three of the specimens chosen as lectotypes in the present 

 paper have been examined by the authors.
