This ant is represented in my collection by a number of workers, 

 soldiers and females (one winged) collected by Mr. Hans Sauter at 

 Kanagawa, Takakiyama and Bukenji near Yokohama; several 

 soldiers and workers collected by Professor J. F. Abbott near the 

 Marine Biological Laboratory at Misaki; one dealated female, two 

 soldiers and two mediae marked "Japan" (Coll. Am. Mus. Nat. Hist.) 

 and a soldier and worker from Chemulpo, Corea (Coll. Phila. Acad. 

 Sci.).

Comparison of these specimens with a long series of our North 

 American C. herculeanus pennsylvanicus convinces me that the Japanese 

 form should rank as an independent subspecies. Not only is the 

 clypeus of the soldier longer and more projecting, and the anterior 

 border of the head red, as Forel has pointed out, but the head is 

 narrower and has more flattened sides than in the American form 

 (see Fig. 2a and b). The types of japonicus are in the Leyden Museum.
