AFFECTING THE CEDAR OR ARBOR VITA. 
EUPITHECIA MISERULATA Grote. 
Although the moth is very common, occurring all over the Eastern 
United States, flying about and entering our houses through the sum- 
mer, the caterpillar is rarely met with, though it is liable to prove lo- 
cally injurious to cedar hedges and ornamental trees. We have reared 
the moth from caterpillars found on the low bush juniper (Juniperus 
communis), and descriptions of the larva and chrysalis will be found in 
Bulletin 7 of the U. 8S. Entomological Commission, p. 248. The follow- 
ing descriptions were drawn up from a specimen living during the last 
week of August, the chrysalis appearing September 30 on the cedar in 
Maine, the moth appearing the following spring, early in May, in con- 
finement: 
Larva.—Body slender, the sutures between the segments well marked and stained 
with yellow. The head small, rounded, not bilobed, and not so wide as the body. 
Uniformly pale green, exactly concolorous with the leaves of the cedar, on which it 
feeds. The lateral fleshy ridge of the body is marked with greenish-yellow, forming 
a prominent, interrupted, greenish-yellow lateral line. Supra-anal plate very short; 
smooth, obtuse at the apex, the edges marked with greenish-yellow. Anal legs thick 
and short, not broad; no dorsal warts or tubercles, the body being smooth. Length 
12mm, 
Pupa.—Green, slender. Length 7-gmm, 
AFFECTING THE FIR, SPRUCE, AND HEMLOCK. 
EUPITHXCIA LUTEATA Pack. 
This is a common caterpillar on evergreen trees, excepting the pine, 
and is described in Bulletin 7, U. S. Entomological Commission, p. 237. 
The caterpillar is rather flat, the surface granulated, the body reddish 
and bearing a remarkable resemblance to a red, dead fir leaf. It turns 
to a chrysalis late in August and early in September in Maine, and the 
moth appears the following May and June. 
The moth differs from Hupithecia miserulata in the much longer, more 
pointed fore wings. The palpi are also larger, acute, and black. It 
has four regularly-curved, parallel black lines on both wings; it is also 
characterized by the broad, clear, flesh-yellow or luteous band situated 
between the discal dot and the extra-discal line. Expanse of wings
