will be mentioned again among those of the 4th subgroup. Its 

 size is : long. 4i-5 lines. It occurs in South and West Australia. 

 I have an example named by Dr. ChajDuis. 



P. PACHYTA, Sp.nOV. 



A rare species in my experience. I ha^•e an example named 

 by Dr. Chapuis. It is entirely of testaceous colour. The pro- 

 thorax is without fovete, and is somewhat widely explanate at 

 the sides. The suture is non carinate. Its size is 4| lines. It 

 occurs in IST.S. Wales. 



P. IXCERTA, Chp. 



Dr. Chapuis says that this is testacea, Marsh., (nom. prteocc). 

 I am unable to verif}'^ this statement, as testacea is absent from 

 the specimens in the ]Macleay Collection which are believed to 

 be Marsham's types. I have an example named by Dr. Chapuis 

 which is the smallest example I have seen of this subgroup (long. 

 3.7 lines). It is extremely close to ^Jcichi/ta, Chp., (only doubtfully 

 distinct in my opinion), but the example before me has the sides 

 of its prothorax less noticeably explanate.

Ovata; fortiter convexa, fere subgibba ; sat nitida, capite 

 prothoraceque subopacis exceptis; testaceo-brunnea, antennis 

 apicem versus paullo infuscatis; capite crebre subtilius non- 

 nihil aspere punctulato; prothorace quam longiori fere \it 2^ 

 ad 1 latiori, fere ut caput sed paullo magis crebre (ad latera 

 paullo magis fortiter) punctulato, utrinque late leviter planato 

 sed vix manifeste foveolato, lateribus leviter arcuatis, 

 latitudine majori fere ad basin posita, angulis anticis acutis 

 sat prominulis posticis subrotundatis ; elytris vix striatis, 

 distincte 10-seriatim punctulatis, interstitiis planis subtiliter 

 punctulatis, parte marginali ut series punctulata; antennis 

 sat gi-acilibus; pi'osterno baud canaliculato; tibiis anticis sat
