PINE CATERPILLARS. 



783 



Moth. — Body and wiags white, tinged on the veins with ocherous, speckled and. 

 banded with rust red. Fore wings whitish at base ; beyond, a broad diffuse brown 

 band as wide as the thorax ; beyond, an equally broad, white baud, with scattered 

 brown specks, and inclosing the large round discal spot. A broad, extradiscal band, 

 separated by a white band or line of varying width from the brown margin of the 

 wing. Hind wings white, less densely speckled and banded than the fore pair, with 

 a large, round discal dot. Fringe smoky-brown, with narrow, white checks. Hind 

 wings white, usually less densely speckled and banded than the anterior pair, some- 

 times with three irregular brown bauds, two beyond the large round discal dot ; a 

 marginal brown line, which is sometimes wanting. Abdomen and legs whitish. 

 Length of body. .36 to .40 inch ; expanse of forewings, .95 to 1.15 inches. 



109. Zerene catenaria (Drury). 

 (Larva, Plate xxxii ; figs. 3, 3a, 3b, 3c.) 



What was without much doubt a belated caterpillar of this speciea 

 was fouud on the white pine October 5, but the body was not so 

 clear a yellow, and the two black spots on the side of each segment 

 were not well defined. A chrysalis was also beaten out of a pitch pine 

 August 31 ; another out of a hackmatack August 30. The moths from 

 these chrysalids appeared September 15 and 16. From these facts I 

 think this caterpillar occasionally at least feeds upon different conifer- 

 ous trees. Its food plants, however, are the blackberry, woodwax, and 

 wild indigo, though in Maine I have found it most abundant on Carex 

 pennsylvanica. 



Larva. — Head as wide as the prothorax, full, roundeU, distinctly bilobed, ash-brown, 

 finely dotted with dark, and with six to seven large black dots on each side. 



Body a little thicker at first abdominal feet than elsewhere ; the body slightly 

 widening towards this point ; it is cylindrical, the segments wrinkled above.

The body is above and as a ground color a light yellowish ocher-brown, with 

 yellow-ocher patches here and there ; with broken, fine lines, one pair on each 

 side dilating on the back of each segment into a minute black dot, one behind the
