880 Mr. A. M! Lea's Notes on 



to constitute a distinct variety ; in all of them the meta- 

 sternum and abdomen (except the two apical segments and 

 apices of the others) are black ; in the males there is a 

 small blackish blotch in the middle of the prothorax (in 

 two of them this blotch has a greenish, in the other a 

 bluish gloss) ; all three have an infuscate streak along the 

 face, and in one the vertex is black. In one of the males 

 the dark parts of the elytra are confined to the punctures, 

 in the others only the apex is pallid (except for dark 

 punctures) ; in the female all the punctures are dark and 

 there is an irregular transverse space towards the apex 

 where the colour is darker than elsewhere. 



OcHROSOPSis EROSUS, Saund. 



From New South Wales, Victoria, Tasmania and South 

 Australia there is a species which in several museums 

 bears the name of erosus, and really appears to be that 

 species although the legs and a widely triangular patch on 

 the metasternum are black ; in all other particulars, how- 

 ever, it agrees with the description. It should perhaps 

 bear a varietal name. The species was described originally 

 as from the Swan River. 



OcHROSOPSis AUSTRALis, Saund. 



A specimen from the Swan River appears to be referable 

 to this species ; the vertex of its head, however, is black, 

 whilst that of australis is described as ochraceous yellow. 

 A similar specimen from South Australia is in the Macleay 

 Museum. 



OCHROSOPSIS ERUDITUS, Baly. 



(Plates XXIII, XXV, figs. 56, 164.) 



Dr. Baly's specimen had broken antennae ; in both sexes 

 the antennae are as described by him, bvit in the female 

 the sixth and seventh joints are wider than in the male ; 

 in both the eighth and ninth are also compressed, but to a 

 less noticeable extent, the tenth is slightly compressed and 

 the eleventh is almost cylindrical except at the tip ; the 

 antennae of the male are considerably longer than those of 

 the female. In two specimens before me the prothorax 

 has a small black median spot — rounded in one (a female), 

 produced in the form of a wedge towards the base in the 

 other (a male); on the latter the metasternal episterna
