7wa{/o. —Reddish-black, with translucent spaces on seg- 

 ments 2 to 5 of the abdomen, one on each side of a dark 

 median longitudinal hne. Caudal setae annulated. Wings 

 vitreous, with the marginal and submarginal areas reddish- 

 brown. Legs reddish, the fore and hind femora with a black 

 band in the middle. Length, 9 mm. ; of the wing, 10-12 mm. ; 

 of the setae, 16 mm. 



Suhimago. — Wings light- grey, with dark neuration, with 

 an ill-defined irregular dark cloud enclosing a light space.

 Imago. — Dark-brown, the segments of the abdomen broadly 

 tipped with black, the third to the sixth with a pair of trans- 

 lucent yellowish spots. Setae annulated. Wings vitreous ; the 

 fore wings with a brown spot at the base of the costa, and with 

 less distinct ones in the marginal area at the bulla, and in the 

 pterostigmatic space. In the marginal area there are, in the 

 male, 7-8 cross-nervules before the bulla and 11-13 beyond it ; 

 in the female there are 9 before and 18 beyond the bulla. 

 Length of body, 3 6 mm., ? 9 mm. ; of the wings, g- 7-8 mm., 

 5 11 mm. 



Suhimago. — Wings dark-grey, with black neuration, the 

 nervules of the fore wings edged with darker ; their scarcity 

 behind the subcostal in the middle of the front of the disk 

 gives rise to the appearance of a pale spot, whilst the mutual 

 approximation of three or four about the bulla, and again in 

 the midst of the pterostigmatic space, produces frequently two 

 dark spots. 



Locality. — New Zealand. 



Genus Colobubiscus, Eaton (1887). 



Imago. — Legs all functional ; hind tibia longer than the 

 femur or the tarsus ; tarsi 5-jointed, the fifth joint rather in- 

 distinct ; first joint of the hind tarsus shorter than the second ; 

 ungues in all the tarsi dissimilar. Posterior wings well 

 developed, oblong-oval, with the dilatation of the marginal
