Fouud ou the stem and branches of Japanese Chestnut-tree {Castanea saliva, 

 v av. jupon ica Ito), planted in my garden in Koishikawa, Tokio. Ils gait is rather 

 swift. It is a timid ant, and when approached, hides ilself by clinging flally to 

 the stem or branches 



Both ? major and minor were observed and many spécimens were collected, 

 but Ç, Q , are yet unknown to us. 



Professor Dr. A Forel called my attention to C. Rothneyi Forel enumerated 

 by Wheeler («The ants of Japan», in Bull. Am. Mus Nat. Hist. XXII 1906, 

 p. 327), who based his materials ou a single soldier and deiilated female, collec- 

 ted by Sauter at Okayama. Whether Wheeler's ant from Okayama may be 

 identical with our variety or not, can only be determined with ample materials, 

 especially Ç and ? major, at hand. 



(T0K.UTAR0 Ito.) 



J'ajoute que le C. tokioensis Ito se distingue, en outre, par 

 l'absence d'impression sur l'épistome et par la sculpture plus faible 

 du devant de la tête chez la grande £, puis, par l'épinotum un peu 

 concave (en selle) chez la petite £. 



Depuis le travail de Wheeler sur la faune du Japon (Bull. Amer. 

 Mus. of Nat. History, 17 sept. 1906, vol. XXII, pp. 301-328), 

 5 nouvelles formes du Japon ont été décrites : 1° Camponotns 

 Habereri Forel, 2° Lasius spathepus Wheeler, 3° Apliaenogaster 

 Sehmîtzi For. r. japoniça Forel, 4° Myrmica rubra L. r. Kurokii 

 For., 5° Myrmica rubra L. r. Kotokui Forel. Ajoutons-y encore les 

 4 formes ci-dessus décrites.
