new or little-hioicn Tipulidae. 207 



(/. W. Campbell) ; Mt. Ida, Otago, February 20, 1922, 

 6 (^ c? at 4000 feet ; 8 c^ ? at 4500 feet ; 2 c? c? at 5000 feet 

 (Geo. Hoives). 



The green tints above described presumably fade into 

 ocbreous in old specimens. The species is named in honour 

 of the collector of the type-specimen, Mr. J. F. Tapley. 



Macromastix campbelHj sp. n. 



General coloration light green, the prsescutum with three 

 orange-fulvous stripes ; wings faintly infuscated ; thoracic 

 setae microscopic ; ovipositor with the tergal valves separated 

 by a profound notch. 



Female. — Length about 9*2 mm. ; wing 11*7 mm. 



Frontal prolongation of the head yellow, darker laterally ; 

 palpi brown basally, passing into black. Antennae short, 

 the scape greenish yellow, the first flagellar segment brown, 

 the remainder of the organ black. Head, pale brown, 

 whitened on the anterior part o£ the vertex ; no apparent 

 vertical tubercle. 



Pronotum light green. Mesonotal praescutum light green 

 with three orange-fulvous stripes ; scutum green, each lobe 

 with a conspicuous orange-fulvous area ; remainder of meso- 

 notum light green. Thoracic setae sparse and microscopic. 

 Pleura greenish, testaceous. Halteres brown. Legs with 

 the coxae and trochanters pale, tinged with green ; femora 

 pale brown ; tibiae broAvn, the tips narrowly darkened; tarsi 

 dark brown. Wings with a faint brown tinge ; cell Sc and 

 the stigma darker brown ; veins dark brown. Venation : 

 as in M. tapleyi. 



Abdomen pale brown, the segments more or less tinged 

 Avith green, especially the basal tergites ; terminal segments 

 darkened. Ovipositor very different in structure from that 

 of M, tapleyi^ the valves of the tergite separate, the incision 

 between the valves so deep that it extends beneath the caudal 

 margin of the eighth tergite; sternites not produced into 

 chitinized spines. 



Hab. New Zealand (South Island). 



Holotype, ? , Purau, Banks Peninsula, February 19, 1922 

 (J. W. Campbell). 



This interesting species is named in honour of the collector, 

 my friend Dr. J. W. Campbell, Macromastix campbelli and 

 M. tapleyi are closely allied, in spite of the different structure 

 of the ovipositor. The green tints, especially conspicuous 

 in carupbelli, may fade in old specimens, but the colours seem 

 to be as permanent as in species of the viridis group.
