ANAXO. 



A. sy dney anus (? cere as, Blaekb., var.). Femina. Ab cereo difFert 

 prothoracis lateribus paullo minus arcuatis, antennis (non- 

 nullorum exemplorum artic-ulo 2' rufescenti excejDto) totis- 

 nigris. 

 I took three specimens of this insect on flowers near Sydney, 

 and am in doubt whether it should be regarded as a distinct 

 species or merely a local race of the Victorian A. cereus, Blaekb. 

 I have seen a good many females of the latter, in all of which the 

 antenna? have all the joints, excej^t the first and the apical two 

 or three, bright-red in their basal half (in some specimens almost 

 entirely red), while in all these Sydney examples the antennae 

 are quite black, except that in one of them the second joint is a 

 little reddish, the sides of the prothorax at the same time being 

 certainly straighter, which makes that segment appear a little 

 more elongate. Since I described A. cereus I have obtained Bt 

 specimen which I regard as the male of that species. It differs 

 from the female in being much smaller (long., 3 J 1.), and in 

 having its antenna? and femora black, and its hind tibipe con- 

 siderably dilated. It must be remarkably like the insect which 

 Mr. Bates described as ChroynomcFct U7iicoIor, but it is certainly, 

 I think, the male of Anaxo cereus, and I feel convinced that 

 A. cereus, female, cannot be separated generically from 

 A. hrevicornis, Bates (the type of the genus), of which its author 

 says that he had seen only the female — indeed, A. cereus and 

 hrevicornis are very close even as species, though certainly distinct.

TRICHOSALPIXGUS. 



T. obscurus, sp. nov. Obion go-ovatus ; minus nitidus ; subtiliter 



pubescens ; crebre (prothorace minus crebre) punctulatus ;, 



obscure brunneus, tarsis testaceis ; antennis prothoracis 



basin attingentibus ; prothorace quam caput vix latiori, sat

Very like T. brun7ieus, Blaekb., but much smaller, difierently 



coloured, and having the punctu ration of the prothorax much less 



crowded, and the basal impressions of the same very much feebler,
