the preceding five joints ; the apical joint is of equal width but 

 longer and pointed at the extremity. The head and prothorax 

 ure covered moderately closely with rather large punctures ; 

 the punctures on the elytra are a little smaller and about 

 equally close. 



Compared with Conopalpus hrevicollis, Kraatz, to which the 

 insect bears a certain superficial resemblance, besides the dif- 

 ferences in the antennae, palpi, &c., indicated in the generic 

 •diagnosis above, the thorax is less transverse (being a little 

 more than half again as wide as long), much more rounded at 

 the sides, and more coarsely punctured ; the head is much less 

 bent down ; the elytra are very similarly punctured; the whole 

 insect is also very much smaller. There are some traces of a 

 •central longitudinal keel, and some discal farrows ou the 

 thorax which are sufficiently irregular to suggest the idea of 

 their being abnormal. 



This is a very interesting addition to the Australian fauna. 

 Hitherto no member of the family has been noticed as Aus- 

 tralian except the Queensland Orchesia elongata, Macl., which 

 is about as different from T. hicolor as one species can be from 

 another within the limits of the same family. 



A single specimen occurred near Port Lincoln. I have no 

 record of the particulars of its capture.

A. Anqasi, Pascoe. Ihis seems to be a very variable insect. 

 In a series before me that appear specifically indistinguishable 

 the size varies from 51. to 91., and the apex of the elytra 

 Taries from being nearly quite rounded to being distinctly 

 truncate or even emarginate (without either apex of the emar- 

 gination being spined, however). In some specimens only the 

 apex of the pale spot on the elytra is present, so that there ap- 

 pears to be merely a very small spot placed behind the middle 

 of the elytra. In some specimens, too, the thoracic punctura- 

 tion is very sparing, or even almost obsolete, and the tubercles 

 are very ill-defined ; in some the base and apex of the elytra 

 are rufescent. In the males the hind tibiae are a little arched. 

 The third joint only of the antennae carries a defined spine,
