648 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



2. Noctuid larva. 



The larva here described occurred June 10 at Providence. 



Larva. — Head large, as wide as the body, deep shining amber-red. Body smooth, 

 rather thick, of a rich velvety reddish brown above, bounded low down on the sides 

 by a Avhite line, below which the sides are reddish flesh-colored. The three anterior 

 pairs of abdominal legs are livid, while the anal and thoracic legs are reddish. 

 Length, 17™™. 



3. Acidalia ? sp. 



This caterpillar occurred at Providence June 10, both on the pig- 

 hickory and hop-hornbean. Though they were abundant, they did not 

 live in confinement. 



Larva. — Body very slender ; head large, flattened in front, otherwise full, rounded, 

 and wider than the body, which is very slender, of uniform thickness, with no tuber- 

 cles; smooth, with a prominent lateral ridge. Anal legs large and broad ; supra-anal 

 plate large, equilaterally triangular. Head, body, and legs yellowish green, with 

 no spots. Length, 12'"™. 



4. Coleophora ottryce Clem. 



The larva, according to Clemens, mines the leaves of iron- wood ( Ostrya 

 virginica) in October and during spring. 



The case is flat, rather wide, and the edges nearly parallel except 

 near its mouth. The upper edge is slightly curved, and almost at the 

 hinder end is a slight notch, which is sometimes wanting, and the 

 hinder end is squarely excised. Color of the case pale reddish-brown. 



5. Aspidisca ostrywfoliella Clem. 



The larvae may be found on the leaves of iron-wood during the latter 

 part of September and early in October. 



About the 10th of October all the mines are untenanted. There may 

 be a spring brood in the leaves of the Ostrya, but I have not observed 

 any. 



The mine is large when compared with those found in the leaves of 

 other plants, and the hole left by cutting out the disk is out of propor- 

 tion to the size of the mined portion. (Clemens.) 



6. Nepticula oatrymfoliella Clem. 



The larva in July and August makes a rather wide, most frequently 

 much contorted, transparent mine, with a narrow, central, black line 

 of " frass; " sometimes the early portion of the mine is filled up with 

 " frass," and in others the line of " frass" is distinct from the beginning. 

 From the middle to the end of the mine whence the larva escapes it will 

 average nearly a line in width. (Clemens.) 



7. Nepticula virginiella Clem. 



In the leaf of iron- wood, Ostrya, it makes a very narrow long track, 

 not broader than the width of the larva, the interior of which is filled
