CADDIS-FLIES. 57 



" In the New Zealand examples the posterior wings have a fuscous dash at 

 the anal angle, but they do not sufficiently differ from the Australian to 

 warrant their separation specifically " (Hutton). 



I am unacquainted with this insect. 



Genus MICKOMUS, Eambur (1866). 



The base of the costal area of the fore-wing narrowed and without a 

 recurrent nervure. Sub-costal area with one basal cell. 

 Distribution. — Tasmania and New Zealand. 



MICKOMUS TASMANIA. 



Hemerobius tasmanice, Walker, Trans. Ent. Soc. of 

 London, ser. 2, vol. 5, p. 186. 



This extremely delicate and beautiful little insect has 

 occurred at Wellington, but at present no other precise 

 locality is recorded for it in New Zealand. 



The expansion of the wings is from ^ to \^ inch. 



" Dull red ; head tawny, with a band, a stripe, and a point on each side, 

 hindward dull red. Thorax with some tawny marks. Legs whitish. Wings 

 narrow, almost vitreous ; the veins whitish ; fore-wings pubescent ; veins 

 rather few, with brown points." 



This species may be recognised by its very small size 

 and brilliantly clear wings, without excisions, which are 

 frequently ornamented with numerous sharply denned 

 black dots. 



The larva of this insect probably feeds on aphides, but. 

 is unknown at present. 



The perfect insect may be met with throughout the 

 year, but is never common. It is sometimes disturbed 

 from amongst foliage ; but it is more frequently observed 

 on the lower surfaces of objects resting partially on the 

 ground. I have often met with it in the depth of winter. 



This species was originally described from specimens, 

 taken in Tasmania.
