 apice subtruncatis. 

 Hab. Rockhampton. 

 This insect approaches the species of the 2iid section, and 

 indeed much resembles some of them, though the antennas and 

 tibiae are not so very narrow as in that group. The specimen 

 before me is, I beUeve unique, in the collection of Mr. Masters. 



Arthropterus Howittii. 



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



Rufus nitidus punctatus, antennis subangustis articulo primo 

 parvo quadrate, 2-9 longitudine baud ter latioribus, oculis 

 nigris, thorace subquadrato tenuiter canaliculate ad latera 

 antice subrotundato postice vix angustato, elytris apice 

 subrotundatis, tibiis subangustis extus acute terminatis. 



Hab. Victoria, 



The thoi'ax in this species is very much of the same character 

 as in Westwoodii, WtjanamattcB, &c., but the antenna3 and tibiae 

 are very different. The joints 2 to 9 of the former are not three 

 times broader than long bat are more than twice. The tibiee are 

 wider than in A. Wilsonii but very m.uch narrower than in the 

 preceding group. 



Arthropterus brevicollis. 



Long. 4| lin., lat. \^ lin. 



Piceo-rufus nitidus leviter punctatus, antennis subangustis 

 articulo primo parvo quadrato ceteris longitudine bis 

 latioribus, oculis pallidis, capite inter oculos depresso, thorace 

 subtransverso tenuiter canaliculato postice transversim 

 impresso, elytris longis apice subemai'ginato-rotundatis, 

 tibiis subangustis extus acute terminatis. 



Hab. New South Wales. 



Very like the last species, but differs in the narrower antennae 

 and thinner puncturation and in having the thorax a little
