with in certain lights, and especially in freshly-captured specimens 

 a purple gloss ; wings dark fuscous with a golden bronze effulgence ; 

 legs black with black spines and hairs, those of the tibiae and tarsi 

 of the anterior pair tinged slightly with rufous. The whole head, 

 thorax, and abdomen are closely punctured, the punctures on the 

 head coarse and shallow ; a space round the ocelli and the front 

 between the antennas are smooth and shining, and the occiput behind 

 is fringed with a little rufous pubescence. 



$ Differs from the $ only in being smaller, and in having as in 

 all Scoliadse straight instead of cornute antennae. 



I have only procured this species in the Pegu hills, and in the 

 vicinity of Moulmein in Tenasserim, where it is rare ; Smith gives it 

 from the Philippine Islands, and Guerin's type specimen is, according 

 to Saussure, labelled " India orientali."

This insect so closely resembles Triscolia capitata, that for some 

 time I confounded it with that species. The neuration of the 

 anterior wings, however, shows that it belongs to a different sub- 

 genus. Other slight points of difference are, that in this species the 

 mandibles and the entire clypeus are .always, and a portion of the 

 antennae is sometimes, fuscous black : the wings, as a rule, also have 

 far less of the brilliant coppery effulgence of T. capitata. 



In Burma, D. molesta is a fairly common insect. In August and 

 September I have found it frequenting the flowers of a thorny 

 creeper (Acacia pennata).
