the Australian Longicornia. 565 



bead concave between the eyes, and without an impressed line ; 

 antennae much shorter than the body, the last six joints shortly 

 triangular, the third and fourth beneath, and the fifth ringed with 

 white in the middle ; prothorax punctured, much longer than 

 broad, slightly tuberous at the sides, with two spreading callosities 

 at the base, the disc entire ; scutellum very transverse ; elytra 

 rather elongate, covered, except the two spots on each — one in the 

 middle, the other towards the apex — with short curved scales of a 

 dark-golden tint; body beneath thickly covered with silvery-white 

 scales ; legs with yellowish scales. 



Length 3 1 lines. 



The smallest and narrowest member of the genus, which now 

 contains five species. The last five joints of the antennae are 

 shorter and more transversely triangular, and the prothorax is 

 longer and less irregular than in any other species ; all of them, 

 except Pempsamacra pygvKSa, are remarkable for the beautiful 

 metallic white clothing of the underside. 



Genus Brachopsis. 

 1. Brachopsis nupera. 



B. rufa ; elytris infuscatis ; abdomine pedibusque nigro-chaly- 

 beatis. 



Sydney. 



Head luteous-red, shining, sparingly punctured ; antennae 

 shorter than the body, black, the first joint obscurely marked at 

 the base with reddish ; prothorax impunctate, velvety, luteous-red, 

 rather longer than broad, constricted anteriorly, the side bluntly 

 conical; scutellum small, triangular; elytra very narrow, pale- 

 reddish brown; legs, postpectus, and abdomen, blackish-chaly- 

 beate; antepectus luteous-red. 



Length 6 lines. 



Rather too close, perhaps, to Brachopsis concolor, W. W. 

 Saund., but at the same time I am quite convinced that very few 

 Coleopterists would combine it with that species. Besides the 

 difference in colour, the prothorax is considerably narrower, 

 especially anteriorly, and the tarsi are narrower and longer. This 

 latter character, however, is probably only sexual, and the other 

 differences might be bridged over if we had a larger series of 

 specimens, particularly from localities between Tasmania and 

 Sydney, the homes of the two forms respectively.
