868 FIFTH EEPORT OF THE ENTOMOLOGICAL COMMISSION. 



marked with black and here and there dashed with reddish. Supra-anal plate 

 email and obtusely pointed, and concealing the small dorsal spines. A dorsal iuter- 

 rupted dark stripe and lateral obscure, more or less dark lines. The body is 

 crossed in front of the middle by a curved blackish line, curving anteriorly and form- 

 ing a conspicuous line, being oblique on the sides of the body. The slight hump is 

 black, inclosing a white area in front. An oblique silvery line on each side of the first 

 abdominal legs, and the lateral line is touched with silvery. 



The minor markings are too complicated to describe, but it mimics in appearance 

 and color a twig of the fir. Length 1.5™™. 



21. The red and yellow striped pine span-worm. 



(Plate X, fig. 3; Plate xxxiil, fig. 2, 2a-2/.) 



The larva, described on p. 784, also occurred on the fir on the grounds 

 of Bowdoin College, Aug. 28-31, but I have been unable to carry it 

 through its transformations. The figure on Plate x has been very 

 poorly reproduced by the lithographer ; and fig. 2a, in Plate xxxiii, 

 represents the body as narrowing too much at the end. 



22. The fir tortrix. 

 Tortrix packardiana Fernald.* 



This moth was bred from the fir on Peaks Island, Oasco Bay, Maine, 

 and sent to Professor Fernald for identification (see p. 849). 



23. Tortrix caterpillar. 



This caterpillar occurred on the fir June 26' to 28, at Brunswick, 

 Maine. It began to pupate June 29, making a slight silk cocoon among 

 the leaves at the end of the season's growth. Ichneumoned and died. 



Larva. — Body of the usual shape, full, cylindrical, and soft, with five pairs of ab- 

 dominal legs. Head small, pale greenish amber, with a short black stripe on the 

 side, much narrower than the prothorax which is narrower than the rest of the body. 

 Length, 12">"'. 



24. The pine leaf-miner. 

 Gelechia pinifoliella Chambers. 



The leaves of the fir were found at Brunswick, Me., to be affected 

 by this miner much as in the pitch pine (p. 792), the terminal third of 

 the leaf being paler than the rest. A dead pupa skin was found July 

 15. 



25. The fir scale-insect. 



Lecanium sp. 



On the upper side of a fir leaf a single specimen of Lecanium was 

 found at Brunswick, which was low, flat, broad, oval, blackish, almost 

 as broad as the leaf.
