In the stud}' of the material here presented, it was found that 

 the most satisfactory mounts were made from specimens boiled in 

 a solution of KOH composed of equal parts of water and saturated 

 solution of the potassium hydrate. The material was allowed 

 to boil several minutes, then was transferred to warm water and 

 washed with camel's hair brush until all the coloring matter had 

 left the body. From here the specimens were readil}' transferred 

 to glycerine jelly for temporary study or through the clearing 

 mixture mentioned in the previous paper into balsam for permanent 

 reference. 



I am again placed under obligations to Professor T. D. A. 

 Cockerell who has very kindly read the manuscript and given 

 some notes upon the species here studied. The drawings 

 accompanying this paper were made by Miss Ella Weeks under 

 the author's immediate supervision. Thanks are due her for the 

 care and skill exercised in their production. 



All measurements given, both in text and plates, are in micro- 

 millimeters.

 In older specimens the longitudinal median surface is smooth, this 

 area being fusiform, but not greatly enlarged in the center. Fusi-

 depressions each contain several small pits. The caudal margin 

 somewhat plicate. The edges of body wall not upturned on
