This fine insect is entirely new to me; and from its being so large and so striking I conclude it to be scarce. None of the many residents in that locality had ever seen one before, and were much struck with its size and handsome appearance. For a long time I have been in doubt whether it is not Rh. fractinervis, Vollenhoven; which species, in spots and markings, it greatly resembles, and it is only after long and close study of it, and comparing it with the description given of Rh: fractinervis** “Cat. of Hymenoptera,” etc., by Professor Hutton, p. 128; where, however, it is named Rh. antipodum, Smith: this name, Professor Hutton informs me in a letter, must yield priority to the other. that I have believed it to be distinct. Its much larger size, very peculiarly shaped end of abdomen and lateral yellow spots on its second segment, dark colour of its femora and posterior tibiæ, etc., striped clypeus, yellow margins of the basal joints of antennæ, iridiscent and hairy and dusky-coloured wings, 3 ocelli, etc., have caused me so to determine. Genus Lissonota L. multicolor, sp. nov. Ferruginous, spotted with yellow and black. Head: orbits of eyes, genæ, a narrow transverse line above labrum, and mentum light yellow;
