Thorax. — Dorsum aenous black, the colour not attaining an- 

 terior margin except as a wide stripe in the centre, but extending 

 to both wings and to the scutellum. Humeral calli tawny, with 

 a whitish grey tomentose spot, contiguous to each, on the anterior 

 border. A bluish grey spot in front of each wdng, placed almost 

 on the dorsum. Sides of thorax yellowish grey posteriorly ; meso- 

 pleurse bluish grey. Scutellum yellow, base blackish ; metano- 

 tum blackish grey. 



Abdomen. — Brownish 3^ellow, with a black dorsal stripe on 

 first three segments, which spreads out over the greater part of the 

 fourth and fifth segments, tip of abdomen yellow, sides with a 

 blackish line and a fringe of black hairs mixed with some paler 

 ones. Belly yellowish. Some short pale hairs over the dorsal 

 surface of the abdomen. 



Legs. — Fore coxae yellowish with bluish grey reflections, pos- 

 terior coxie blackish, all of them black at the junction with the 

 femora, which are yellow, with the tips narrowly black, the middle 

 pair having a very small black streak on the under side near the 

 base, and the hind pair a wide black ring in the middle. Remain- 

 der of legs black, but middle tibiae dark brownish yellow. 



Wings. — Pale grey, a rather dark brown middle stripe from 

 the centre of the costa, narrowing posteriorly and reaching hind 

 margin of wing at tip of anal cell ; distal part of wing dark grey, 

 down to the fifth posterior cell, the centre of which is pale grey 

 (reaching to the border) but a rather wide pale grey space remains 

 between the dark brown stripe and the distal dark grey part, this 

 clearer part ceasing at the fifth posterior cell. Fifth longitudinal 

 vein dark brown suffused. Wing rather strongly iridescent. Upper 

 transverse vein placed just before one- third of the discal cell. Hal- 

 ter es yellowish, knob black. 



Described from a single perfect $ in the Indian Museum collec- 

 tion captured by Dr. Annandale. 



N .B. — I describe under the above specific name a 9 specimen 

 (now in the Indian Museum collection) captured by Dr. Annandale 

 at the base of the Dawna Hills, Amherst District (Lower Burma), on 

 i-iii-08, and which I at first thought was a new species. It differs 

 from limbata, O.S., by the presence of the clearer space in the dark 

 distal part of the wing, and by the hind femoral band being in the 

 middle, not near the tip ; other minor differences hardly being 

 specific. My augmented description may enable others to iden- 

 tify it definitely either as limbata or as new. ■ .

A. limbata, Os. Sac. 

 A, calopa, mihi, sp. nov. 



The two former are very closely allied, as noted by the late 

 Baron Osten Sacken (Berl, Ent. Zeits., xxvi, 100) in describing 

 his species from the Philippines. My calopa is also near both, 

 yet I believe all three species to be distinct.
