43-articulatis, nrticulis 15-25 albido-flavis ; terebra? valvulia 

 nigris ; alia hyiilinis, venis fuscis, tegulis testaceis. 

 Long. 9 mm. ; terebrae long, 10 mm. 



? . Differs from ^1. merid'tonalis m havlM<2; the face very 

 finely |tui»ctiired, wiiliout a carina ; the median h)l)e of the 

 niesonotiiin rinely punctured, not reticulate posteriorly ; the 

 first termite transversely ruijulose, the two lon<^itudinal carinje 

 stront>;er than in ineridionalis and reachino; almost to the apex, 

 and the second cubital cell ionj^er, somewhat narrowed to the 

 apex, the second abscissa of the radius nearly twice as long- 

 as the second transverse cubital neivure, and about two- 

 thirds of tlie Ieny;rh of tlie cubital maiiiin of the cell. 



[Jab. Victoria (C French). 



A specimen from Franklin, Tasmania, has the hind tarsi 

 whitish yellow except at the base and apex, but in the type 

 also they are much paler than the other tarsi, and would 

 probably be whitish yellow in lite. 



I have not seen either A. indultor, Erichs., or A. aastrali- 

 anus, Kokuj. A specimen of A. inomatus, Kokuj., differs 

 from the type in having joints 15-21 of the antennaj whitish 

 instead of 15-24 as in the type, and the antennas only 39- 

 jointed instead of 45 ; but another specimen has 41 joints 

 with joints 15-22 whitish. The female of inornatus has the 

 terebra equal in length to the wliole insect. Probably, as 

 Kokouyew suggests, inornatus will prove to be a variety of 

 indultor. The three species of Austrohelcon known to me all 

 have the clj'peus short and the labrum ex[)03ed. 



Trichiohelcon, gen. nov. 



? . Closely allied to Austrohelcon, differing in tlie deeper 

 frontal excavation, in the strong longitudinal median carina 

 of the second tergite, and in the dense hairy covering of the 

 median segment and of the first and second tergites.
