and prothorax of a dull coppery-blue, and one (from Nor- 

 manton) has the head, prothorax, and elytra of a dark 

 greenish-bronze. All these agree in their dull metallic, 

 appearance, due to the shagreened surface, and all have the 

 sides of the prosternum v\dth remnants of striae. 



It is probable that if some of these specimens could be 

 compared with the type of viridiaenea, they would be found 

 to agree with same, but even if this should prove to be the 

 case the name herbacea should be retained as varietal for the 

 form with red prothorax. 



Rhyparida aeneotincta, Blackb. 

 PI. vi., fig. 35. 

 The type of this species is in the Museum. 



Rhyparida posticalis, Blackb. 

 PI. vi., fig. 36. 

 Three specimens of this species, with almost identical 

 elytral markings, are in the Museum. 



Rhyparida amplicollis, Blackb. 

 PI. vi., fig. 37. 



The type and many co-types of this species are in the 

 Museum. The elytra were stated to have "regione suturali 

 antice late subaeneis, latera versus nonnullis exemplis 

 longitudinaliter aeneo-notatis." It is over twenty years since 

 they were described, and possibly some alteration has t-aken 

 place, but there is now not the least metallic appearance on 

 any of them. There is an obscure infuscate blotch (of vary- 

 ing size) in the scutellar region, and on some specimens a 

 vague infuscate humeral spot and a postmedian one on the 

 seventh interstice of each elytron ; on one co-type there is 

 also a vague postmedian spot on the third interstice. The 

 prosternum is without medio-lateral striae, but a few faint 

 ones may be traced at the base. A specimen from the Coen 

 River has very minute punctures on the head; the prothorax 

 and elytra, except for portions of the margins, are deeply 

 infuscated throughout. 



Variety A. Some large (7J-8J mm.) specimens from the 

 Northern Territory (apparently sent with the typical form) 

 and King Sound dijffer in being of a brighter colour, pro- 

 thorax with a vague infuscate blotch towards each side, and a 

 still more vague one in the middle; the elytra with a small 

 post-scutellar space (but the suture throughout), each 

 shoulder and a spot on the fourth interstice, and another on 

 the eighth about the middle, more or less conspicuously
