%X Euconocephalus nasutus (Thunberg) and E. pallidus (Redtenbacher) were quite similar in morphology,but their songs and the stridulatory organs were obviously different. The chirp of the songs of E. nasutus lasts 4 5?ms,consisting of 4 pulse strings with an inter chirp interval of 1 8?ms,and the frequency of highest power peak is about 11 37?kHz. The chirp of the songs of E. pallidus has only one pulse string with an inter chirp interval of 4 3?ms. The pulse string duration is 1 6?ms and the frequency of highest power peak is about 11 03?kHz. The file of E. nasutus is curved with thin ends and enlarged middle portion. The file of E. pallidus is straight,and slightly widened in the middle portion.
