to tl'C pal|)i, all the characters just mentioned are also found 

 in D. iinprcssa. 



In Mr. E. Fleutiaux's collection there is an example of this 

 s|)ecies from Indo-China labelled in IJatcs's han(l\vritin<>: 

 I'ccoptogen'uts viotu/atus, Bates, var. hit'uir, but I cannot find 

 that this name has been published. Several specimens have 

 been taken by Mr. W. \'italis de Salvaza in Cambodia at 

 rnomh-Penh (]]russels Museum), and in Laos at Tavienj^, 

 Vieu Poukha, and Nam Thara. In the British Museum 

 there are two examples, one fromKedah in Siam (S. S. Flower), 

 agreeing uith type, the other labelled Java ; in this latter 

 s[)ecimen both labruui and clypens are more deeply emargiuatc 

 than in the typical form, and joint 3 of the antenna' is 

 distinctly longer than 4 and equal to 5, but I notice no other 

 peculiarities. In the Paris Museum there are also two 

 examples, one from Cochiu-China {Beaudouin), the other 

 from Lakhon, on the borders of Siam and Annam [Hdrnunid).
