Sapporo ; Junsai ; Nikko. The variety is from Nikko. 



Scarcely more than a local variety of tlie European L. arcitata, 

 "whicb is found with little variation throughout Eastern Siberia 

 to the coast of Manchuria. The Japanese form differs from 

 European and Siberian examples chiefly in the basal fascia of the 

 elytra in the male wanting the outer horn of the bow, and in the 

 first and second black fasciae in the female being widely de- 

 tached from the suture. The antennae are longer, and the thorax 

 more angulated on the sides.

 et versus marginem angustatis ; antennis subserratis ; thorace 

 triangular! multo subtilius punctato, fulvo-aureo pubescenti ; 

 elytris subtilissime punetulatis et rugulosis apice recte truncatis, 

 angulis acutis, exteriori producto spiniformi. Long. 17 millim. S • 



Chiuzenji, August 1881. 



Differs from L. quadrifasciata, which occurs throughout Eastern 

 Siberia as well as Northern and Central Europe, by definite spe- 

 cific characters ; the thorax being regularly and straightly dilated 

 from the fore margin to the hind angles, the angles of the elytral 

 truncature spined, and the yellow fasciae different in form.
