248 BOARD OF AGRICULTURE. 



washed with yellow ochreous upon and on each side of the ven- 

 ules. The costal area is yellowish. The legs are pale, concol- 

 orous with the upper side of the hind wings. The wings expand 

 1.35 of an inch. 



It differs from any other native species of this family known 

 to me by the peculiar opaque deep ochreous fore wings, and the 

 large silvery discal dots and two silvery bands and slashes along 

 the venules. It is also found in Massachusetts. 



The moth belongs to an undescribed genus, for which I would 

 propose the name Parennomos, in allusion to its resemblance in 

 the shape of the head and its appendages to the well-known ge- 

 nus Ennomos. It will be more fully described in a forthcoming 

 work on the PhalsenidBe, the family of Geometers, to which it 

 belongs. 



z Saw-Fly larva on the Austrian Pine. — 



.(Fig. 1, a, upper, and b, side view.) Late 

 in September of the last year Dr. William 

 Mack, of Salem, brought into the Museum 

 of the Peabody Academy some singular 

 false caterpillars which had assembled on 

 a single branch of an Austrian pine, on 

 his place, and had tied the needles to- 

 gether with a fine silken web filled with 

 castings, forming a mass of castings, about 

 six inches in diameter, with the needles 

 of the pine among them, the leaves being 

 ^^^- •'• separated by the larvae from the branch. 



This larva is a young Lyda, one of the saw-fly family, and 

 while doing little injury to the tree so far as known, yet merits 

 a short description. Dr. Ratzburg figures a similar species in 

 his work on forest insects, and states that the Lyda campestris 

 of Europe, to which our species seems closely allied, is sporadic 

 in its attacks on the pine, and never proves very destructive. 



The body is cylindrical, a little flattened and thickest in the 

 middle, with small thoracic slender legs which are not used much 

 in walking, the larva wriggling along when placed on a smooth 

 surface. The head is pale reddish with a black spot between 

 the antennae ; the prothorax is black above and the body reddish 

 olive green, with a rather broad purplish line along the middle 

 of the back. There are no abdominal legs, and the end of the
