The adults appear about 20th June. The hibernating larvae probably 

 i-merge from eggs laid in July. In Pennsylvania, as many as 12-14 

 mines have been noticed in one leaf. 



Parornix (Or nix) kalmiella is also recorded as mining in leaves 

 of this shrub. The larvae are found in August and September, and 

 the adults in the following May.

The biology of Alabama argillacea (cotton worm) is described. 

 The life-cycle in Oaxaca (Mexico) on an average covers some 60 days, 

 the egg-stage occupying 3, the larval 30, the pupal 15, and the adult, 

 previous to oviposition, 12 daj^s. There may be from three to five 

 generations, according to temperature and we'ather. It is considered 

 very probable that the moth has some alternative food-plant in this 

 region, and by some growers it is thought to be maize, the irrigated 

 crop of which would enable the insect to survive during February, 

 ^larch and April.

The remedial measures against Dociostaurus maroccanus undertaken 

 in the south of France [R.A.E., A, vii, 432; ix, 137] are discussed, 

 and it is suggested that poison baits should form the principal remedial 

 measure in future campaigns. The ability to forecast the extent and 

 position of any outbreak in 1921 would be of great value in 

 regulating preventive work.

 treatment [R.A.E., A, ix, 110] against Dacns oleae, the conclusions 

 arrived at as a result of observations made in 1907-12 are quoted 

 [cf. loc. cit., i, 174].
