Loew's description fits with two females from Sakhalin and Hok- 

 kaido, so well that I am induced to refer them to this species. The 

 specimen from Sakhalin is Tabamts komurae, Matsumura, without any 

 doubt, from the comparison with his type. He described from rather 

 a denuded specimen, and his description is not accessible for determi- 

 cation of this species. I am obliged to abandon the name, komurae 

 established by him. Therioplectes hirticeps is not very common 

 even in the two Islands of Hokkaido and Sakhalin, as I have records 

 only from Solowiyofka and Jozankei, from July 1 2th to 16th. The 

 female is one of horse-biters, but her attack may not be so severe as 

 that of the following species.
