large ones towards sides. Scutellum semi-circularly triangular 

 and impunctate. Elytra very little wider than prothorax, 

 parallel-sided to near apex ; with regular rows of not very 

 large but conspicuous punctures, becoming smaller pos- 

 teriorly: interstices with very few punctures. Length, 

 3 1 -5 mm. 



Hah. — Australia (C. French); Western Australia: Lake 

 Austin and Cue (H. W. Brown). Type, I. 3398. 



Structurally apparently close to description of Chryso- 

 mela micans, but elytra (on the six specimens in the Museum) 

 not at all green, and antennae pale almost throughout. The 

 basal joint of the front tarsi is wider than the third on the 

 male and about the same width on the female. 



JOHANNICA METALLICA, n. sp . 



Metallic-blue or purple; in places bronzy or brassy. 



Head with irregular punctures dense only on clypeus;: 

 with a fairly large median fovea, and near each side of same 

 a narrow deeply-impressed line, a less deeply-impressed line 

 almost touching each eye. Antennae stout, third joint longer 

 than first or fourth, sixth joint slightly inflated on one side, 

 seventh more noticeably so, the three following joints strongly 

 inflated, eleventh joint rather short and rounded, but semi- 

 double. Prothoraa about twice as wide as long, with coarse 

 irregular punctures, and towards each side with from one to 

 three irregular depressions. Elytra with rows of fairly large 

 punctures, becoming smaller posteriorly, but each elytron 

 with about nine much larger punctures or small foveae (some 

 semi-double) on the basal two-thirds. Length, 9i-ll mm. 



Hah. — Queensland : Stannery Hills and Annan River 

 (H. W. Brown). Type, I. 4857, in South Australian 

 Museum; co-type, K. 18797, in Australian Museum. 



The head is mostly brassy: the antennae are aln:ost 

 entirely deep-purple; most of the prothorax is brassy or 

 brassy-purple, only small parts of the base being bluish, the 

 scutellum is entirely brassy or bronzy ; on the elytra the 

 shoulders and a large subapicai patcli (but not the. extreme 

 apex) are brassy, with the colour rapidly changing through 

 coppery-green to the general purple tone : the larger punc- 

 tures or foveae are more or less metallic: parts of the sterna, 

 base of abdomen, and middle of femora are more or less 

 coppery. The depressions on the sides of the prothorax are 

 not alike on any two of the five specimens before me, and 

 sometimes differ on the sides of an individual ; they are 

 mostlv due to clusters of large punctures. The antennae are 

 very similar to those of gemellata, but the colours of the- 

 prothorax and elytra are very different ; the elytral punctures
