SCALE INSECTS AND Scale.{Lepidosaphes ulmi.)This scale, which resembles an elongate oyster shell in shape(fig. 3, b) has long been known in this country, though believedto be a native of Europe. It is widely distributed and is ex-ceedingly abundant in Maine. Besides seriously injuring appletrees, the twigs of which often densely covered by them, they. Fig. 3.

In June the eggs hatch, the active young appearing as smallwhite specks which soon attach themselves to new shoots bytheir beaks. The scale then begins to form, gradually increas-ing in size. The scale of the female (fig. 3, a, b, c)is less thanone-eighth of an inch long, narrow, usually curved when notcrowded, (fig. 3, c) and nearly the same color as the bark uponwhich it is found. The scale of the male (fig. 3, d) is muchsmaller, less curved and usually not found on fruit trees. Aswith the San Jose scale the adult male is provided with bothwings and legs
