*44. Caconeura notostigma ( Selys) . -

Not previously known from the mainland of Sumatra. S. Lampoeng Res.: 5 ♂ ♂. Mt. Tanggamoes. Gisting. Waiteboe . 600 m. Dec, 24-29, 1934, rare. Author leg .

These specimens apply perfectly to the original description after a ♂ from Singapore. I have seen specimens from Sedagang. Pulau Tioman (ex coll. Laidlaw). and a very large series from W. Borneo. which agree closely in all important characters. The anal bridge-vein is well developed and strongly arched in this species. In living males the large bands on the back of the thorax are not deep blue. as in collaris dohrni. but pale bluish green; the wingmembrane is usually tinged with greyish-yellow.
