Lea — On Australian Colf.optera 89 



liles of the male are of such a sliapc that their tii)s can ne\er touch, owing to the 

 cuspidate basal masses: the cus])s (or ohtuse serrations) vary, on the three males 

 before me they are respectively seven and five, five and six. and four and five. 

 The canthus in front of each eye is moderately jirominent. but the head behind 

 each eve is gently rounded. The mandibles . of the female are of the usual 

 feminine type, having a ridge on the upper surface, and an acute inner projection 

 about the middle.

Pascoe proposed two of these names on trivial grounds, and I consider that 

 neither Rctostictc. nor fpoiuoria are rec|uired : the slight differences in size of 

 the facets of the eves (the eyes of F-i. siijnifcnnn and of B. cleroides differ some- 

 what in size, but the facets themselves scarcely differ), and the proportionate 

 lengths of the first and third joints of the antennae are not sufficient to warrant 

 the generic separation of species so dbxiously allied. The synonymy is now 

 somewhat comi)licated l)Ut. referring all the species to BcthcUuin. appears to be
