or less variable in geographical races. But the habit of this 

 author of taking undescribed species as the types of his genera is 

 most objectionable, and no editor should have published work in 

 which such a fault is evident. The form of his tables is also 

 occasionally incorrect or unfinished, making them very difficult to 

 follow. 



Agenta barbatula, sp. n. 



2 • Olypeus transverse at the apex, twice as broad as long ; a 

 tuft of very long pale creamy hairs at the base of the maxilla?. 

 Eyes scarcely touching the base of the mandibles, a little nearer 

 together on the vertex than on the clypeus ; posterior ocelli a 

 little further from each other than from the eyes. Antenna? a 

 little longer than the thorax and median segment combined, the 

 second joint of the flagellum half as long again as the third and 

 at least three times as long as the first. Pronotum nearly as long 

 as the mesonotum, narrowed and rounded anteriorly, the posterior 

 margin very feebly arched. Median segment much longer than 

 broad, with an obscure median sulcus, roundly depressed near the 

 apex. Shining, microscopically p\mctured ; the median segment 

 opaque, finely shagreened. Abdomen ovate, with a short petiole. 

 Tarsal ungues with a tooth beyond the middle. Radial cell 

 broad, second abscissa of the radius nearly twice as long as the 

 third, first recurrent nervure received at the middle of the second 

 cubital cell, second before one quarter from the base of the third 

 cubital cell. Median cell scarcely shorter than the submedian ; 

 cubitus of the hincl wing originating well beyond the transverse 

 median nervure. 



Black ; legs and antenna? dark fusco-ferruginous, mesonotum 

 and abdomen with a bluish gloss. Wings hyaline, a fuscous band 

 crossing the wing at the basal nervure, a broader one from the 

 stigma not reaching beyond the discoidal cell. 



Length 6 mm.

This is the first species of the genus recorded from Australia, 

 for Pogonius lunulatus Sauss. seems to belong to Pseudagenia. 



Agenia gilesi, sp. n. 



$ . Clypeus transverse at the apex, fully twice as broad as long, 

 the labrum exposed and broad. Eyes not nearly reaching the 

 base of the mandibles, the inner margins nearly parallel ; ocelli 

 in a broad triangle, the posterior pair as far from each other as 

 from the eyes. Antenna? scarcely longer than the thorax , and 

 median segment combined ; the second joint of the flagellum equal 

 in length to the third. Pronotum not depressed or narrowed 

 anteriorly, as broad as the head and as long as the mesonotum. 

 Median segment broader than long, steeply sloped posteriorly. 

 Abdomen subpetiolate, ovate, the apical segment broadly rounded 

 at the apex. Microscopically punctured ; head, thorax, and 

 median segment opaque, abdomen shining. Legs not very long,
