Show 1902.] DRAGONFLIES OF T H E " SKEAT EXPEDITION." 87 VESTALIS AMCENA Hagen. Vestalis amcena, Kirby, Cat. Odonata, p. 103; Karsch, Ent, JNachr, xvii. 1891, no. 16, p. 242; Kriiger, Stett. ent. Zeit. 1898, p. 75. Several males and females from Kwala Aring and from the toot of Gunong Inas. This species occurs also in Borneo, Java, and Sumatra. Note.-Two females from Kwala Aring differ rather markedly from the rest of our specimens. The general colour of the body is dark bronze-green rather than emerald-green of the other specimens. Further, the wings have a distinct brownish tinge. In respect to the markings on the head, the yellow is brighter than in the other specimen. One male shows a tendency to have the wings tinged and is also of a more bronze-green shade than the other males. These three specimens are perhaps much more adult than the others. Lesrion EUPHCEA.
