are black on the back and gray on the sides. When fully grown 

 it is more than two inches long. 



In Garden and Forest^ January 15, 1890, Professor Smith 

 publishes an account of a new insect which attacks the elms. It 

 has thus far, I believe, been found no nearer than Newark, N. J. 

 It is an imported species, and although it has been in the country 

 for several years, has only within a short time attracted attention. 



This is a prett}' moth known to entomologists as Zenzera pyritia^ 

 Fabr. Like the preceding, the female is much larger than the 

 male. Her wings spread two and a half inches. According to 

 Professor Smith, the eggs are laid in the forks of the small branches, 

 and " the young larva burrows downward toward the larger 

 branches, tunneling generally through the center, and usually kill- 

 ing the branch." The larva grows until it is over an inch long. 

 It is a white worm, dotted with black, and from each dot comes 

 a black hair. This insect appears to have gained a foothold about 

 Newark, and to be spreading. The only remedy seems to be to 

 cut ofl' and destroy the infested twigs. Several species of the 

 germs Apatcla feed upon the leaves of the elm. 



Apatela aniericana^ Harr. 



This is a gray moth, two or two antl a half inches across the 

 spread wings. The general color of the front wings is a soft, 

 rather light gray, marked, as the figure shows, with lines and 

 blotches of darker color. The light marginal line is also seen. 

 There are also spots of lighter color scattered over the surface. 

 The broad wings are of nearly uniform color, but darker than the 

 front ones, especially in the female. The caterpillar is hairy, 

 rather large, being, when full grown, two inches and a half long. 

 Its general color is dark greenish, varying to blackish, the head 

 being browri. Besides lumierous yellowish, bristle-like hairs, 

 there are longer tufts of black hair, one near the hind end of the 

 body on the eleventh ring, and two on the fourth, and two more 

 on the sixth ring. The feet are black. It appears late in sum- 

 mer, and does not reach its full size until fall. It then goes into a 

 chink, crevice, or any suitable shelter, and changes to a chrysalis, 

 in which it remains until the following summer. These cater- 

 pillars feed upon the leaves of the maple, poplar, chestnut, bass- 

 wood and elm, and perhaps other trees.
