ing four species were taken by Mr. Koebele in the Cairns dis- 

 trict. They seem distinct from all their somewhat numerous 

 congeners that have been described as occurring in JNew 

 Guinea, &c.

An extremely variable species in respect of colouring. In some 

 specimens the elytral dark marks are extremely similar to those 

 of a well marked example of the European 1\ bipunctaius, Fab. 

 The discoidal dark spot on the elytra is present in all the 

 specimens before me, though in some it is smaller and of lighter 

 colour than in others. In a fully marked specimen the shoulders 

 are black, the discoidal spots are very large, the sutural spot is 

 smaller but very dark and all the spots except the humeral ones 

 are narrowly connected. In one specimen the three hind spots 

 of the elytra are all present but are very small and not much 

 darker than the general surface and are all narrowly connected 

 as in a dark specimen.
