Discobola dicycla n. sp. (Fig. 28.) 
Similar to D. dohrni and D. ampla, and perhaps a variety of one or 
other, but shows the following differences: Flagellar joints all about equal 
in length, but becoming slightly and gradually more slender towards 
apex; last joint under four times as long as broad; hairs on upper surface 
rather conspicuous, somewhat longer than joints. Pronotum rather bright 
ochreous, strongly contrasting with dark head and thorax. Abdomen also 
conspicuously paler than thorax. Wing-markings resembling those of 
. dohrni, but those in centre separated from those at base and from those 
towards apex; a complete ring surrounding base of Rs and another below 
this, the two forming central fascia. Discal cell somewhat longer than in 
the other two species. Length of body, 9mm.; wing, 11 mm.

Tipula fumipennis, Hudson, Man. N.Z. Ent., p. 48, pl. v, fig. 2, 1892. 
Given by Hutton as a synonym of D. ampla, but, although it may be 
a Discobola, it seems incredible that the very different wing-markings shown
