T. niger, punctulatus; alis anticis fuseo-mgris, apice hyalinis, posticis hyalinis, basi late fuseo-nigris.

Female. Length 12 lines. Black and closely punctured; the head and thorax slightly shining, the thorax very shining, and not so strongly and closely punctured as the thorax; the anterior margin of the clypeus widely and slightly emarginate.

This fine species of Thynnus is of the same form, and about the same size, as Guerin's T. shuckardi ; it is the second species that has to my knowledge been captured in the Eastern Archipelago; the first species was described in the paper descriptive of the insects of Bachian, & c, published in the supplement to the fifth volume of the ' Proceedings.
