Head wide with crowded punctures of median or rather 

 small size, becoming larger and denser on clypeus. Antennae 

 thin, extending to about middle of metasternum. Prothorax 

 more than twice as wide as long, basal two-thirds parallel- 

 sided, thence gently rounded to apex; punctures in middle 

 much as on head, but less crowded, becoming denser and 

 larger towards sides. Elytra elongate, parallel-sided to near 

 apex ; towards suture with a few irregular rows of punctures, 

 b>ut elsewhere larger and crowded. Prosternum with coarse 

 punctures in places, the sides transversely or obliquely 

 strigose ; inter-coxal process with a row of large punctures, 

 its base conspicuously bilobed. Length, 6-8 mm. 



Hah. — Western Australia: Cue, Ankertell (H. W. 

 Brown), Sandgate (H. J. Carter). Type, I. 2598. 



There is a subdentif orm swelling at the base> of each of 

 the front claws, so that these could not be regarded as 

 simple, but on the other claws the swelling, although trace- 

 able, is not dentiform in character, hence the species might 

 have been referred to Chrysomela ; but as it is quite obviously 

 allied to lauta, and to the preceding species, it appears better 

 to refer it to Calomela ; from lauta is differs in being more 

 metallic, narrower, and by the conspicuous row of punctures 

 on the inter-coxal process of prosternum (on a specimen 

 marked as lauta by the late Rev. T. Blackburn, and on others 

 of the species, the process is wider and without such a row). 

 The antennae are thinner than in most species of the genus. 

 Although the specimens could hardly be described as black 

 with a metallic gloss, their upper-surface is certainly not of 

 the bright metallic-blue or green (wholly or in part) of 

 others of the genus, and there are no sharply-defined bands 

 of colour on the upper-surface, but on the same specimens 

 some of tlie punctures are bluish and others are purplish 

 and greenish. The elytral punctures are deep and well 

 defined, but (except towards the suture and on the margins) 

 many of them are so closely placed together that they appear 

 to be transversely or obliquely confluent, and the majority 

 are slightly wider than long. 



Some specimens from Cue are much smaller (4J-4f mm.) 

 and have the punctures on the inter-coxal process fewer in 

 number and the groove containing them deeper ; but they 

 appear to represent a variety only. 



Calomela prosternalis, n. sp. 



Black, with a bronzy gloss, becoming bronzy-green on 

 parts of the under-surf ace ; labrum, antennae, palpi, and 

 parts of legs, more or less obscurely diluted with red.
