fcJpEciMENS EXAMINED. — One. the type. 



Kemaeks. — The principal characters of this mu»ang, as exhibited 

 in an adult female obtained on Tiomau Island by Messrs. Ablx>tt and 

 Kloss in 1899, were first noted by "Mr. Oerrit S. Miller (Proc. Wash- 

 ington Acad. 8oi., 19W, p. 228;, after whom, now that its distinctness 

 has Ijeen proved by the two further examples taken by Mr. H. C. 

 Robinson (one in the British and one in the Selangor Museum), I 

 have much pleasure in naming the species.
