346 MISCELLANEA ENTOMOLOGICA. 



punctured, and has the elytra more hairy. The transverse de- 

 pression on the scutellum is very deep in the present species. I 

 have some specimens in my collection from the same locality as 

 this insect, which differ in having black eyes and being of a 

 darker hue, but I scarcely think they can be of a distinct species. 

 The name Wyanamatta is derived from the Geological term 

 for the shale, which abounds in the district of Camden. 



Arthroptekus angulatus. 

 Long. 4<| lin., lat. 1| lin. 



Piceus nitidus crebre punctatus, antennis latissimis brevissimis 

 articulo primo lato angulato, thorace quadrato piano cana- 

 liculato ad latera antice late rotundato postice subangustato 

 ciliato, elytris subtruncatis angulis humeralibus ciliatis, tibiis 

 posterioribus apice late rotundatis. 

 Hab. Rockhampton. 

 This species is of a very dark colour, densely punctured, and 

 covered on the sides of the thorax and elytra with short strong 

 hairs. The first joint of the antennae is broad and produced at 

 the external angle. The thorax is broad, flat and very broadly 

 rounded at the anterior angles. 



Aethropterus sqbcylindricus. 

 Long. 5 lin., lat. 1| lin. 



Piceo-rufus nitidus punctatus, antennis latissimis brevissimis 

 articulo primo subacute angulato, thorace capite latiori 

 quadrato subplano canaliculato angulis anticis rotundatis, 

 scutello ad basin transversim impresso, elytris apice leviter 

 trisinuatis, tibiis posticis^extus apice oblique trnncatis. 

 Hab. Bogalong, near Yass. 

 I believe this species to have a wide range throughout the in- 

 land districts of New South Wales. It is more nitid, less punc- 

 tate, and less hairy than the last, and is also of a lighter hue. 

 The thorax though much rounded near the anterior angles, has a 

 very broad square aspect. The transverse impression on the 

 scutellum is near the base, and not very deep.
