The feature by which this genus may be most readily 

 identified is the punctuation of the elytra ; the punctures across 

 the middle are usually in quite regular, closely placed rows, 

 although towards the base some of the rows run out at the 

 suture, and some of them disappear about the apex, but on 

 the apical slope the punctures are quite (or almost) as large 

 as elsewhere. On some of the species the interstices between 

 the punctures appear almost costiform, on others some of the 

 interstices are more distinctly elevated than the others, and on 

 mtdticarinata the elytra are acutely costate in a rather curious 

 way. The species are all compact, glabrous, and metallic, 

 and they usually have more or less reddish legs. Seen from 

 behind, the protliorax appears to be considerably narrowed in 

 front, but this is largely due to the front angles being strongly 

 depressed below^ the middle. The sexes differ in the abdomen 

 and legs. The genus, except for one species that occurs in 

 Southern Queensland and parts of New South Wales, appears 

 to be confined to Northern Queensland, and its nearest ally 

 is perhaps Cleorina, although it is not very close to that genus. 

 Typical species, bii?}i2)ressa. 



Following is a table of the species (^4): — 



A. Elytra with numerous conspicuous abbreviated 



carinae multicarinafa 



AA. Elytra without such. 



B. Sutural stria without punctures on apical 



slope simiata 



BB. Sutural stria with punctures there. 



C. Protliorax with ordinary punctures ... inultiseriata 

 CC. Protliorax with reticulate punctures. 

 D. Fourth abdominal segment of male 



with a curious median process ... ventralis 

 DD. Fourth segment without such. 



E. Hind tibiae of male widest at middle hiimpressa 

 EE. Hind tibiae of male widest at apex. 



F. Legs mostly pale ]ninrfatosf)iatn 



FF. Legs mostly dark ohscurijjes 



Trypocolaspis biimpressa, n. sp. 

 PI. riii., fig. 151. 

 d . Metallic ; under-surface black, in places obscurely 

 diluted with red, labrum and appendages flavous or testaceo- 

 flavous, apical half of antennae usually infuscated. 



Head with rather small, dens^e, reticulate punctures; 

 feebly or not at all depressed along middle. Antennae extend- 

 ing to about middle of abdomen, second joint stouter than 

 but scarcel}'' as long as third, third to sixth subequal in length, 



(94) There are two females of a species as large as rmilticarijiata 

 from Port Denison in the Macleay Museum ; they probably belong 

 to a new one, but as it seemed possible that they were unusually 

 large specimens of punctatostriata, they were not described.
