from Forel's description, but differs in so many details of 

 structure, sculpture, and colour that I have felt constrained 

 to describe it as new. It is more easily distinguished from the 

 other Australian species of the subgenus Myrmogonia : evae, 

 Forel ; oetlxeri, Forel; adami, Forel ; lownei, Forel ; gihhinotus, 

 Forel; and ruhiginosus, Mayr. 



24. Camponotus (Dinomyrmex) subnitidus, Mayr. 



To this species I refer a single minor worker taken between 

 Todmorden and Wantapella. It is, however, even less 

 pilose than the typical subnitidus, and probably represents a 

 distinct variety, which cannot be satisfactorily described till 

 the worker major is brought to light. 



25. Camponotus (Myrmamblys) aurofasciatus, n. sp. 

 P']. Ixvi., fig. 7. 



]\ork(^r (medio [?]). — Length, 5-5"5 mm. 



Head strongly trapezoidal, very slightly longer than 

 broad, broader behind than in front, with straight posterior 

 border and sides and rather sharp posterior corners, convex in 

 the middle above, feebly depressed behind. Eyes moderately 

 large, convex, nearly circular, well behind the median trans- 

 verse diameter of the head. Mandibles with rather straight 

 external borders, 6 -toothed. Clypeus distinctly but bluntly 

 carinate, with feebly rounded, entire anterior border. Frontal 

 area obsolete, frontal groove distinct, frontal carinae approxi- 

 mated anteriorly, curved and diverging behind. Antennae 

 long, scapes extending nearly half their length beyond the 

 posterior border of the head. Thorax through the pronotum 

 nearly as broad as the head, rapidly narrowed and laterally 

 compressed behind, so that the mesonotum and epinotum are 

 reduced above to a rounded ridge. Pronotum broader than 

 long, flat above, anteriorly and laterally distinctly submar- 

 ginate. In profile the thorax is highest in the mesonotal 

 region and the dorsal outline is an even curve continued over 

 the epinotal base, which is fully three times as long as the 

 declivity. The angle separating the base from the declivity 

 is rounded and obtuse. Promesonotal suture distinct, that 

 between the mesonotum and epinotum obsolete. Petiole 

 thick and rather narrow, very convex in front, flat behind, 

 with blunt, evenly-rounded, and entire apical border. Gaster 

 broadly elliptical, rather flattened. Hind tibiae slightly 

 compressed. 



Opaque and very densely and finely punctate; mandibles 

 slightly shining, with numerous large, elongate punctures* 

 Clypeus and cheeks with a few sparse, shallow foveolae. Th®
