3. MICROMERUS AURANTIACUS De Selys. 



The collection iiiude })y Doctor Abbott contains a single male from 

 Khow Sai Dow Mountain, Trong, Lower Siam, January-February, 

 181)9. Abdomen, 13.5 nun. inleng-th; hind wing, 16,5; opaque spot on 

 front wing, 3.5 in length. Abdomen basally ^^ellow, passing into red 

 apically. Probably the jiredominance of one of these colors over the 

 other is entiri;ly a matter of age. J/i minandali Laidlaw, described 

 from a single male from Mabek, Hulu Jalor, seems scarcely distinct 

 from aanmtlacus originally described from Malacca.

 have been described as new: 21. inartlnx Karsch," from Sumatra; 

 M. slgnatiis Kriiger,'' from Java and Penang; M. a^nls Laidlaw,'' 

 from Kwala Aring; M. annanddll Laidlaw,'^ from Mabek, Hulu Jalor. 

 Nineteen specific names have been proposed in this genus, and of 

 these it is remarkal>le that only one is certainly a synonym.
