another on the fourth, and the tliird on the fifth — and four bands 

 beneath, one on each abdominal segment, except the last, sulphur- 

 yellow ; last abdominal segment above and below ochraceous ; 

 antennae reddish-brown ; legs ferruginous ; prothorax transverse, 

 angulated at the sides ; elytra rounded at the sides, slightly di- 

 verging posteriorly, the apex pointed. 



Length 7 lines. 



The form of the elytra at the apex is something like that of 

 Hesthesis 'plorator, but the elytra themselves are much shorter. 

 The short prothorax, with its angulated sides, is very distinctive 

 of this species. 



5. Hesthesis vesparius. 



H. niger ; elytris truncatis, sutura late grisescente-marginatis, 

 basi humerisque aureis ; antennis ferrugineis, articulis qua- 

 tuor basalibus nigris. 



New South Wales. 



Black ; front, sides of the prothorax anteriorly, base of the 

 elytra and their anterior angles, and the first, second, third and 

 fifth (at the margin) upper segments of the abdomen golden-yel- 

 low; patches on the episterna of the metathorax, sides of the first, 

 middle of the second, the whole of the third and fourth lower 

 segments, fulvous ; prothorax equal in length and breadth, the 

 sides very slightly and regularly rounded ; scutellum black, trian- 

 gular ; elytra rounded at the sides, obliquely truncate inwards 

 and downwards, a very broad, greyish sutural stripe from the 

 shoulder to the apex, at the upper part of which, near the scutel- 

 lum, is a rich yellow spot, below this at the angle is another spot ; 

 legs and antennae reddish-ferruginous, the latter with the four 

 basal joints black. 



Length 7 lines. 



The form of the prothorax, and the coloration of the elytra and 

 antennae, will serve to distinguish this pretty and very distinct 

 species.
