Ainigma Splendens: length 10’. This magnificent insect is 
of a beautiful green, with apurpletingeat the base of the elytra; 
head with some scarce punctures ; parts of the mouth and 
antenne black; the latter hirsute, except on their first article ; 
thorax broad, but much narrower behind than in front ;

body brilliant, and of a blackish green ; legs black

Brachimde. 
This tribe, which is numerously dispersed almost all over 
the world, is most scantily represented in New Holland. 
Of its different genera one alone, which is almost of a tropical 
form (Pheropsophus), has been found till now on that con- 
tinent. The Pheropsophus Verticalis, of which Dejean made 
an Aptimus, is rather common ; I have it from Brisbane; Syd- 
ney, Melbourne, and Adelaide, but it is much more abun- 
dant in the eastern colonies than in the southern. It is sub- 
ject to considerable variations in its colouration, the thorax 
being sometimes entirely black, sometimes yellow with the 
only exception of the anterior margin, and often spotted, with 
these two colours. All these varieties are found in the 
different localities I have mentioned. 
Mr. Howitt, the explorer, brought from Cooper’s Creek a 
variety of this insect, in whicha humeral yellow spot is often 
seen, and in one specimen the yellow spots have so much 
expanded that the elytra seem to be of that colour, with 
four black spots on each, two being sutural and common to 
both. The specimens of Pheropsophus from the north of 
Queensland form a different species. 
Pheropsophus Australis: length 84’; head orange colour, 
with a black transversal band between the eyes; thorax 
black ; elytra of the same coiour, without any posterior 
yellow margin, but with a rather narrow transverse 
yellow and sinuated spot a litle before the middle; inferior 
parts of the body black; under side of the thorax marked 
with orange cclour; parts of the mouth, antenne, and legs 
orange ; knees black. |

Note—This sort is very nearly allied to Verticalis, but 
easily distinguished from it by its larger size, its elytra 
rather longer, without the terminal bordure, the colour
