Trichaulax marginipennis, Macl. 



Of this species Macleay says "not very shining" ; but 

 specimens in good condition are quite highly polished. Mac- 

 leay also described the elytra as having a broad margin of 

 yellow pubescence, and the under-surface as having greenish- 

 yellow clothing. On specimens in good condition, however, 

 the clothing is quite white. 



SCHIZORRHINA ATROPUNCTATA, Kirby. 



PI. ix., figs. 58, 59, 60; pi. xiii., fig. 188. 



This species usually has three round spots on each elytron, 

 two post-median and one subapical; sometimes there is an ad- 

 ditional spot close to the scutellum, and sometimes only the 

 two postmedian ones are present. A specimen in the National 

 Museum, Melbourne (fig. 58) has three spots on the right 

 elytron, and four on the left. Mr. W. D. Dodd has recently 

 taken two specimens at the Coen River, each of which has 

 five spots on each elytron, the extra one being on the shoulder. 



In the female the middle of the metasternum is produced 

 to in front of the middle coxae, then there is a bisinuate suture 

 with the mesosternal process projecting forwards to between 

 the front coxae ; the whole of the produced parts being 

 glabrous. In the male the process is distinctly shorter, and 

 is clothed to the bisinuate suture. 



var. IMMACULATA, n. var. 



From Northern Queensland, there are now before me five 

 specimens (and I have seen others) that differ from the typical 

 form in being of a dingy greenish-yellow and with the elytra 

 immaculate. Part of the metasternum is blackish and part 

 of the abdomen reddish. The sexes differ as in the typical 

 form.

Lyraphora obliquata, Westw. 

 PI. ix., figs. 61 to 64; pi. xiii., fig. 185. 



This is a very variable species, both sexually and in- 

 dividually. The males vary in length from 13 to 18 mm., the 

 females from 17 to 20 mm. 



On the male there is usually an irregular black M on 

 the prothorax, usually connected with the base at two places. 

 Imt sometimes at three, and occasionally completely divided 

 down the middle. On each elytron there is an oblique vitta 

 from the shoulder to beyond the middle, strongly narrowed 

 at its middle, and then dilated till it touches the suture and
