it to any other. It is a Rhyparida. In colour it is of a more 

 or less dingy testaceous or flavous, deepening to a dull (on 

 some specimens almost a blood) red, and with conspicuous 

 black or infuscate markings. These on the head usually con- 

 sist of a fascia in front, connected along the middle more or 

 less widely with a rounded, medio-basal spot. On the pro- 

 thorax there is usually a very large spot on each side, but 

 these are frequently so extended that only the extreme apex 

 and sides are reddish. The scutellum varies from red to black. 

 On each elytron there is a fairly-wide variable vitta near the 

 side, extending from the shoulder to about the apical third or 

 fourth ; the suture is usually black or infuscated throughout, 

 but towards the base the black portion is usually rapidly (sub- 

 triangularly) dilated, and then just behind the scutellum 

 suddenly truncated, and at its widest part it is frequently 

 joined to the sublateral vitta; on the fourth interstice beyond 

 the middle there is usually a narrow spot, but sometimes it is 

 alogether absent, either through the space there being pale, or, 

 if dark, forming part of the sublateral vitta. Each side is 

 usually narrowly black, with the black part either isolated or 

 joined to the sublateral vitta in one or two places. The sides 

 of the prosternum, except the extreme margins, are striated 

 throughout, but more deeply towards the base than elsewhere, 

 and on some specimens more deeply than on others. On 

 hrtvilineafa (some varieties of which approach some varieties 

 of this species) the prosternum is occasionally vaguely striated 

 at the base, but apparently never on the sides or apex. 



A specimen from Moreton Bay, sent by Mr. Arrow for 

 examination, and as having been compared and agreeing with 

 the type of simplex, is simply a fairly dark specimen of 

 australis; its prothorax is almost entirely dark, but the elytral 

 markings are of the usual type. In the original description 

 the colours of the prothorax and elytra are not mentioned, 

 apparently being included in the general expression "rufo- 

 niger."

The elytra of this species vary from brassy-green to 

 purple ; with the shoulders and apex occasionally obscurely 

 diluted with red (but apparently never conspicuously reddish). 

 The legs are seldom entirely pale, but usually have the knees,
