P<EDi'scA anr/ustiora'na. Apricot Moth. 

 As soon in May as one of the leaves of 

 a Peach, Nectarine, or Apricot, is seen 

 rolled up, destroy the little caterpillar 

 within the roll, and watch for others, 

 because the eggs of the moth from 

 which that caterpillar came continue to 

 hatch for several weeks. The moth is 

 the Narrow-winged Eed Bar, Ptedisca 

 anymtiorana. The caterpillars appear 

 during May and June : they are about 

 half-an-inch long, are pale yellowish- 

 green, and with the head brownish- 

 yellow. A few bristles are scattered 

 over the body. It is a very active cater- 

 pillar, wriggling about in most varied con- 

 tortions when disturbed, crawling with 

 equal facility backwards and forwards, 

 and letting itself down by a single thread 

 from its mouth. It passes into the state 

 of a brown shining chrysalis, rolled up 

 in the same leaves, and from this the 

 moth comes forth in July. The moth 

 is very small, not longer than a fourth- 

 of-an-inch. The fore- wings are reddish- 

 brown, in bands of various degrees of 

 darkness. The hind-wings are dusky. 

 .It deposits its eggs, probably, upon the 

 branches, where they remain all the 

 winter, and the caterpillars are most 

 frequently found upon the Apricot.

POISONOUS PLANTS. Gardeners should 

 be much more careful than they usually 

 are in handling the plants they culti- 

 vate, for many of them have deadly 

 qualities. M. Neumann, chief gardener 

 of the Paris Jardin des Plantes, says 

 that pruning knives and hnnds washed 

 in a tank after they have been employed 

 upon some of (he exotics, will destroy 

 the iish it contains. MtypdmanQ bi-
