XI. — Descriptions of One new Genus and Six new Species 

 of Hymenoptera Terebrantia from Queensland. By W. F. 

 Kirby, F.L.S., F.E.S., Assistant in Zoological Depart- 

 ment, British Museum (Natural History), South Ken- 

 sington. 



The following species were received, among others, from 

 Mr. Gilbert Turner, of Mackay, Queensland, for identification ; 

 and as they are of considerable interest I hasten to describe 

 them. 



Tenthredinidae. 



Hylotominjz. 

 Hylotoma apicale, sp. n. 



Exp. al. 10 millim. ; long. corp. 5 millim. 



Male. — Head and thorax black, face below the antenna? 

 testaceous ; antennae ciliated ; front tibia? and tarsi whitish ; 

 abdomen luteous, the terminal segment and the hinder half 

 above, except on the sides in front, black. Wings brownish 

 hyaline, iridescent. 



Female differs as follows : — head rufo-testaceous ; abdomen 

 luteous, with only the apex black ; antennae pubescent, not 

 ciliated.

This is the first species of the genus described from 

 Australia. It is a small species, not closely allied to any 

 other.

 equilateral triangle below, testaceous : segment 7 testaceous,
