of the adult females of stimpsoni from the Loochoo Islands ; while in the 

 other two individuals of the same sex from the same locality, all the joints 

 are simply cylindrical, but the fifth and eighth joints are neither black in 

 color nor thickened in any way, as they should be in stimpsoni according 

 to Kraepelin's characterization of that species. I am, therefore, inclined 

 to think that the characters of the flagellum is also subject to variation as 

 the animal grows. 



As before stated, the distinction of the two species was based only 

 on the females, and the male of the species stimpsoni was not known. 1 

 Fortunately enough there are three males ofthat species among my speci- 

 mens. These males do not differ in the least from those of the species 

 crucifcr, and so in identifying them by the key of Kraepelin, I have always 

 reached the species crucifcr without any difficulty. 



Granting my identification to be correct, and in view of the variation 

 of females with respect to the characters of the abdominal ventral plate 

 and of the tarsal flagellum, it seems warranted to amalgamate the two 

 species into one and to adopt for this the name of stimpsoni, according to 

 the law of priority. As a consequence, the diagnosis of the species may 

 be put down as follows :
