ATTACKING THE LEAVES. 34S Fig. No. 206.—The Native Currant Saw-fly. Pristiphora grossrdarlce Walsh. Although this is not a very common insect, it has beenreported as destructive from several localities. In its per-fect state it is also a saw-fly, resembling the imported species(see b, Fig. 356), yet there are differences which the entomolo-gist can readily de-tect, that place thisinsect in a differentgenus; such as thearrangement of theveins on the wings,the close resemblanceof the sexes, and themarked difference inthe relative size ofthe two insects, the native species being but two-thirds thesize of the imported one in all its various stages. The larva (a, Fig. 356) of this species is always green, andis never ornamented with black spots, which are so numerouson the imported insect as it approaches maturity; neither dothe young larvse gather in large numbers on one particularleaf, but are from the first scattered over the bushes.
