Belonging to the group of Glenea Delia Thorns., Clytia Thoms, and chalybaea Illig. (= picta Weber and Fabr.) which group is sufficiently characterized by the obsolete shoulders. The new species is very closely allied to and strongly resembles Glenea Delia Thoms. of which I have three typespecimens (from Java) before me, but is at once distinguished by the fulvous posterior tarsi and the similarly colored apex of the posterior tibiae, which in Delia are blue-black. Moreover in affinis the white stripes are narrower and the white spots smaller than in Delia which gives the insect a much darker appearance. Finally the sides of the thorax in affinis are more parallel in consequence of the less divergent basal angles.
