Subfamily CHALCOPHORINI. 



Amongst the material sent from the National Museum, 

 Melbourne, occur three new species, which are described 

 below, together with a new Ghalcotaenia taken in some quan- 

 tity by Mr. H. Brown. Of these, Chrysodema subjasciata is 

 the first record of a genuine member of this genus from 

 Australia, Chrysodema saundersi, Macl., proving to be a 

 iJyphogastra. 



Synonymy. — Gyphogastra pistor, C. and Gr. = Chrysodema 

 saundersi, Macl. 



I have examined the presumed type of C. saundersi in 

 the Macleay Museum, though, as usual with Macleay, it is 

 not specially marked as such. There are also four specimens 

 similarly labelled in the Masters Collection in the same 

 Museum. They are all identical with Gyphogastra pistor, 

 C. and G., except for slight individual differences incidental 

 to all the species in this subfamily. 



I have specimens of Chrysodema aurofoveata, Guer., from 

 Banks Island, Torres Straits. It is, therefore, extremely likely 

 to occur on the mainland, but I have not seen airy other 

 specimens besides those in my collection. 



Chrysodema subfasciata, n. sp. 

 PL ix., fig. 2. 



Elongate-ovate. Above blue-black with green or coppery 

 impressions (in fresh specimen covered with yellow or orange 

 flocculence) , underside green or coppery, more or less obscured 

 by yellow flocculence, legs and tarsi blue, antennae with three 

 basal joints blue, the rest reddish. 



9 . Head with triangular excavation on front, medial 

 sulcus fine at base, deep on excavate portion : the raised parts 

 irregularly punctate, epistoma with triangular excision at 

 apex ; antennae not quite extending to base of prothorax, 

 third joint cylindric, as long as first, four-eleven subtriangu- 

 lar. Prothorax bisinuate at apex, feebly so at base, middle 

 lobe of apex advanced and subtruncate, sides nearly straight, 

 feebly sinuate near hind angles, all angles acute, the anterior 

 depressed, posterior slightly produced; disc with a slightly 

 raised medial convexity bounded by a rugose salcus on each 

 side, an oblique flocculent impression partly following the 

 front margin of anterior angles, and an oval patch behind 

 this near the middle of each lobe : the smooth raised parts 

 sparsely punctate, the sides rugose-punctate. Scut ell urn 

 round, convex, smooth. Elytra subangularly widened at 

 shoulders, sides nearly straight on anterior two-thirds, thence
