o82 description;* of xew species of Australian coleopteka, 



CHKVSOMELIDAE. 



Cadmus fasciaticollis Lea. 



Mr. H. J. Carter and I rfi'ciitiv touk .^i.x sin'ciuR'Us of this sjiecies. at Laun- 

 eeston and Cradle Mountain, in Tasmania, tliat aurue in colour witli llii- tyi)e. 

 except that, ou two of them, from four to six of the ajiii-al joints of the antennae 

 are more or less deeply infuseated. Tliree other specimens, from Warataii and 

 Wihnot, differ considerably, however; of tliese a female has the prothoracic fascia 

 extended so as to occupy most of the disc, but not touching' any of the margins; 

 its elytra are blue-black at the base, with a wide extension along the middle to 

 the summit of the apical slope, and a narrow extension from each shoulder, the 

 tips of its antennae are lightly infuseated ; a second female has the prothoracic 

 fascia irregularly extended so as to touch the base in places and to leave hut |iale 

 edgings at the sides and apex; its elytral marking's are less extended tlian on the 

 other female, and the antennae are entirely yiale; the third specimen, a male, lias 

 the prothorax dark excejit fm- a naiTow edging at apex and sides, the elytra are 

 dark except for part of the apical slope, a narrow marginal strip on each sidis 

 and an obscure post-humeral spot, the two apical joints of its antennae and tii)s 

 of several of the preceding ones are infuseated. 



DiTROPiDUs ocHROPrs Er. 



'I'he type was described as having <lark hind femora, and several specimens 

 before me have them dark: but they are usually no darker than the others. The 

 species occurs in Soutli Australia (Mount .Lofty, Adelaide and ^fonnta) as well 

 as in Tasm'ania. 



DiTROpinrs ^ aurichai.ceus Suff . 



Numerous specimens from Xew South Wales (Gosfi.rd, Sydney, and Taui- 

 wortlil and Victoria (Dividing Range) agree witli specimens identified by Black- 

 burn as belonging to this species. They have tlie upper surface uniformly bronzy 

 and the leg's bright red; the ])ronotum densely and finely strigose at tlie sides 

 and apex, but with punctures only on the rest of its surface; tlie eyes are rather 

 close together on the male. 



DiTROPIDUS AMABILIS Balv. 



Xumerous specimens from (Queensland ( I'uiidaberg, Rockhaiiipton, and 

 Oayiidah ) probably belong to tliis s])ecies; tiicy are chisc to I), liiericollis, Imt liave 

 the |)i'othorax more metallic, with denser imni'lures (especially on the sides, lint 

 they are nowhere oblong as noted for .1. (iniiiliilis) and the dypeus not in the form 

 of a narrow transverse ridge; the ahdomen is usually entirely pale in the female, 

 largely infuseated in the male. 



DiTROPiiu's imriniATrs P.Mly. 



Ten specimens before me,- 2.2,5 — 3.25 mm. in h'ugth, jirobably lielong to D. 

 (limidiatir."; they have tlie prothorax decidedly longer than is usual in the genus, 

 its median leng'th being fully two-tliirds of t!ie median leiigtli of the elytra, and 

 witli rather dense and sharply defined punctures, becoming more crowded on the 

 .«ides; the prosternal process is deeply, on Hie male almost triangularly, notched. 

 Ill the original description the prothorax was noted as "distinctly and somewhat
