758 DIPTERA OF AUSTRALIA, 



New South Wales the country has not been searched for Tipulidse ; 

 only incidental or conspicuous specimens have been obtained by 

 collectors whose pursuits were more particularly otherwise directed. 

 There is most probably a wealth of material yet to be gathered, 

 but unfortunately the investigators are limited. 



The number of species referable to this division of the Tipul- 

 idee, with which Australia has hitherto been credited, altogether 

 does not exceed twenty-three. From this total four names must 

 be sunk as synonyms, whilst a fifth, Gynoplistia constans, Saund., 

 of Walker's list, seems to be that of an undescribed insect ; the 

 number being thus reduced to eighteen. This, however, must be 

 supplemented by the names of three characterized species, viz. : — 

 (1) Gynoplistia annulata, Westw., erroneously described as a 

 native of North America, (2) Libnotes strigivena, Walk., originally 

 found in New Guinea, and (3) Conosia irrorata, Wied., from Java, 

 now recorded from Australia for the first time. To the final total 

 of twenty-one species known to occur in this country, descri]:)tions 

 of about eighty new ones are added in the following pages. 



It has been found necessary to introduce five new genera ; one 

 each in the sections Limnobina and Limnobina anomala, and 

 three in Eriopterina. Though feeling very reluctant to propose 

 new genera there seems to be no alternative in each case where it 

 has been done. Besides these fresh genera, the genus Geranomyia 

 has been split up into three sub-genera for the reception of species 

 found to possess two-, three-, and four-jointed palpi respectively ; 

 also, a sub-genus of Rliyijliolopliiis is characterized. The entirety 

 of the species are distributed as follows : — Limnobina [genera 

 Dicranomyia 14, Thrypticomyia (gen.nov.) 1, Geranomyia 4, 

 Limnohia 1, Trochohola 1, and Libnotesl]; Limnobina anomala 

 [Ehamphidia 4, Ori^narga 2, Leiponeura (gen.nov.) 2, and Teu- 

 cliolabis 1] ; ^movT^'E.nmK^Rhypholophus 2, Molophilus 16, Tasio- 

 cera (gen.nov.) 2, Erioptera 1, Trimicra 2, Gnophomyia 1, Gonio- 

 myia 1, Rhahdomastix (gen.nov.) 1, Lechria (gen.nov.) 1, Tren- 

 tepohlia 1, and Conosia 1] ; Limnophilina [Limnophila 16, Gynop- 

 listia 18, and Cerozodia IJ ; and lastly Amalopina [genus Ama-
