 yellow spot in the middle above, and also an elongate yellow one laterally,

Obs. 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 Eh. fractinervis* 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 tibiae, etc., striped clypeus, yellow margins of the 

 basal joints of antennaa, 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, 

 genae, a narrow transverse line above labrum, and mentum light yellow ; 



* " 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.
