A Revision of the Mantispidae of Japan. 



By 



Waro Nakahara. 



In spite of the fact that the Mantispidae of Japan have been 

 studied by MacLachlan n , Miyake' , Okamoto'*' and others' , I have 

 had the good fortune of discovering a new species from the Province 

 of llarima. This I propose to describe in this paper, at the same 

 time improving the opportunity by adding some remarks on all other 

 species of the family found in Japan. 



The wing venation has been regarded by many entomologists as 

 one of the most important characters for the systematic of the Mantis- 

 pidae. This is no doubt true to a degree, but for the purpose of 

 specific distinction I have found it to be much too variable a character 

 to rely upon. 



Family M ANTISPID/E- 

 Subfamily Mailt ispinae. 55 



Genus Eumantispa Okamoto. 



Okamoto, Zool. Anz., xxxvii, p. 299 (1911). 

 So far as known, this genus seems to be peculiar to Japan.
