This genus is closclj allied to Amblj'terus, but difl'ci-s in 

 liaving the mentiim more regularly iiavrowed in front and niore 

 tnmcate, and only tlic lavger claw oi' the anterior tarsi is split, 

 whereas the larger claw of all the tarsi is split in Amhlyterus. 

 Lacordaire says, that this clav is not „fissile" in the anterior 

 pair, but that is evidently a mistake; he states also, that the 

 labrum is very prominent in the middle. I have only dissected 

 one specimen, and in that it is not prominent at all in the sense 

 in which the term is used with regard to the species of this 

 family. I do not trace any membraneous border to Mesystoeclws. 

 and it is so slight in Amhlißerus, that it is seldom visible.

Queensland, Moreton Kay. 



Clypeus denselv rugulose, with the fine reflexed margin 

 pitchy black. Head blackish, with a spot in front yellowish, 

 thiekly and rather strongly punctured, less so on the Vertex. 

 Thorax one third broadcr than long, convex, ])itchy-yellow, not 

 very thiekly but rather strongly punctured; the sides arcuate, a 

 mesial line and an irregulär })atch on each side (all sub-confluent) 

 bronzy-black. Elytra a tritle broader than the thorax, a little 

 longer than broad, with two double lines of rather strong 

 punctures on the dorsal region of each, and fotir lines on the 

 sides; the broad interstices with strong punctures, which have 

 a tendency to form irregulär lines. The margins are beset with 

 short stifl' hairs. The underside is variegated with brownish- 

 black, moderately pubescent. 



Amblyterus Mac Leay. 

 Die Körperform ist hochgewölbt, nach hinten mehr oder 

 weniger verbreitert. Das Kopfschild ist l)ei cicrilricouHS halb-
