Australian G'ixtelidae. 59 



of femora and tarsi (sometimes wholly or in part) black, labrum 

 yellow. Head coarsely punctate, the punctures denned, round and 

 not very close, eves widely separated and prominent, antennae long, 

 extending to the basal third of elytra in the $ joint 1 tumid, 2 

 very short, •'! cylindric, 4-10 shorter than .'5, but wider (elongate 

 ovate). 11th shorter and much finer than 10, Prothorax longer than 

 wide, sub-cylindric, more convex and a little narrowed in front, 

 slightly depressed behind, truncate at apex and base, distinctly but 

 more finely and sparsely punctate than on head (as in Ae virescens, 

 Boisd.), medial line distinct, but not quite continuous to the apex, 

 and a large basal foveate depression. Scutellum very small and 

 transverse. Elytra one and a-half times wider than prothorax at 

 base, shoulders prominent and squarely rounded, sides gradually 

 tapering to a finely pointed apex; striate punctate, the striae deep, 

 the seriate punctures encroaching on the raised intervals, .the latter 

 much more sharply convex than in Ae virescens, Boisd. Underside 

 finely pubescent, and minutely punctate, procoxae contiguous, post 

 intercoxal process slightly rounded, mid-tibiae rather strongly 

 curved, hind tibiae of cf flattened and hollowed on the inside, of 

 $ rounded. Legs, especially the posterior, very long, claw joints 

 of tarsi very fine. 



Dimensions. — c? 10 x 2.2 mm., $ 11 x 3 mm. 



Habitat. — North Sydney (Dr. Clark), Gosford and Blue Moun- 

 tains (the author), Dorrigo (W. Heron). 



Four specimens, 3 cf, 1 2, examined The maxillary palpi 



base the last joint narrowly cultriform, the short terminal joint 

 of antennae, unarmed femora, navicular form, long legs give it a 

 position between Bates's Alcmeonis and Licymnius, but on his plan 

 would still require a new generic title. There are distinct metallic- 

 reflections on the upper surface. It may for the present be con- 

 sidered as an anomalous member of the genus Alcmeonis, the long 

 legs, antennae and coxal structure prohibiting its inclusion under 

 Ghromomoea. The prothorax is much as in Aethyssius, the antennae 

 show an alliance with Anct.ro. Types in the author's coll. : —
