352 MISCELLANEA ENTOMOLOGICA, 



broader than the length. It approaches A. denudatus Westw. 

 or at least what I take for that insect, for I am not by any means 

 sure of its identity. 



AeTHROPTEEUS P0LITD3. 



Long. 6i lin. lat. 1| lin. 



Rufo-piceus nitidus leviter punctatus, antennis angustis arti- 

 culo primo parvo oblongo, oculis pallidis, capite postice 

 subproducto angulato, thorace quadrato breviter profunda 

 canaliculato ad latera transversim bifoveato, elytris subti- 

 liter punctatis subtruncatis, tibiis angustis. 

 Hab. Liverpool Plains. 

 The joints 2 to 9 of the antennae are in this species little 

 broader than the length, and the tibiaB are as narrow as those of 

 A. Wilsonii. It most resembles A. Kingii, but differs inter alia 

 in the broader and squarer thorax. 



Aethropteeus latipennis. 

 Long. 51 lin., lat, 2 lin. 



Rufo-piceus nitidus latus subplanus leviter punctatus, antennis 

 angustis articulo primo quadrato, capite inter oculos bi- 

 impresso, thorace subquadrato canaliculato ad latera antice 

 late rotundato ciliato postice angustato obsolete transversim 

 impresso, elytris latis longis apice late subrotundatis, tibiis 

 angustis extus acute terminatis. 

 Hab. Flinder's Range, South Australia. 

 The antennte in this species are even narrower than the last, 

 while the tibice are broader, but its most distinctive character is 

 the large, broadly rounded thorax. It is unique in the Museum. 

 The genus Phymatopterus Westw. contains the species piceus 

 and Macleayi of Westwood, the latter originally taken by him for 

 Arthropterus Macleayi Don. Considerable confusion exists as re- 

 gards the identity of Donovan's species, and mistakes have, con- 

 sequently, been frequently made. 



As I possess the original specimen from the Cabinet of Fran- 

 cillon, I am enabled to speak with certainty on the subject. A. 

 Macleayi is a narrow species, with elongated thorax, and is found
