having seven and the outer five, but in the figure the outer is 

 shown as having six, whilst the inner is not clearly defined. 



On the specimens before me the tubercles vary from a rather 

 bright red to the general colour of the elytra, and are somewhat 

 variable even on the ditferent sides. The inner row is generally 

 composed of four distinct and more or less conical tubercles, with 

 a few less distinct ones, the whole ranging in number from four to 

 eight. On the outer row the distinct tubercles vary from four to six, 

 with usually a few smaller ones or enlarged granules towards the 

 base. 



Pascoe also describes the elytra as not wider than the prothorax, 

 but in the figure ihey are shown on measurement to be one fourth 

 wider, and this is about the case in the males before me. 



606. DIALEPTOPUS MACILENTUS Pasc. 



A specimen in the Museum collection bears three labels ((Duboul. 

 W. Aust. » « li.macilentus Pasc.S. Austral. » and (cdeterm Mr. Pasc.» 

 It differs from the description, however, in having six tubercles in 

 the outer row and seven in the inner, instead of four and seven. 



607. BUBARIS (1) PITHEGIUS Pasc. 



There are numerous specimens before me which probably belong 

 to this species. In the original description, however, Pasgoe says 

 asingulo elytro postice tuberculo oblongo obtuso obsito ». All these 

 specimens (including one from Monaro, the original locality), ho- 

 wever, have two tubercles on each elytron, crowning the posterior 

 declivity; the inner tubercle is considerably largerthan the other, and 

 although often quite round in outline, is sometimes suboblong. 

 Seen from behind the four tubercles are quite conspicuous, and the 

 declivity below them is smoother than the rest of the elytra. 



This species, whether it is pithecius (as I believe it to be) or not, 

 differs considerably in its granules These are frequently numerous 

 and clearly defined, on other specimens they are almost obsolete, 

 so that the surface has a much smoother appearance. On the 

 prothorax many of the granules could fairly be regarded as 

 tubercles. 



(1) In this and several other genera of Aviycteridcs Pascoe describes the eyes 

 as being partly covered by the ocular lobes, but this is a character which 

 depends to a certain extent upon accident, and there is probably no species in 

 which the eyes in living specimens are not capable of being entirely freed from 

 the prothorax.
