A much paler form occurs in Dunedin ; it was described by Mr. Philpott 
as Gelechia sparsa, poor specimens accounting for the mistake in the genus. 
I have been able to observe and rear a long series of both forms; the pale 
variety does not appear to occur in the North Island, whereas in Dunedin 
both forms have been reared from the same food-plants, the lighter variety 
being by far the commoner. Mr. Philpott’s description appears in Trans. 
N.Z. Inst., vol. 50, p. 128, 1918. 
To his description may be added that the costal half of the forewing is 
far more densely irrorated with brown than the dorsal half. The size of 
the moth varies considerably according to the amount of food available. 
xamining all the stages and characteristics in the life-history of these 
two forms, I could find no points of difference whatever, and conclude that 
the pale form is only a southern variation of the dark species. I under- 
stand Mr. Meyrick has come to the same conclusion without any reference 
to the early stages. 
Distribution. 
become almost a pest in some localities. There are probably two, if not 
three, generations; larvae, pupae, and imagines may be found through- 
out the summer months, though the best time to collect mines for rearing - 
purposes is towards the end of November.

Egg-laying. 
. Eggs laid singly and firmly attached to upper surface of leaf, generally 
in close proximity to midrib or one of the coarser veins. a relatively 
large and easily found by the naked eye. Numbers of ova may be found 
on T leaves, but are presumably not all deposited by the one parent ;
