Our common Hepialus, H. niiistcliiius, is not uncommon at Bruns- 

 wick, Maine, resting on the trunks of spruce trees in July. The trees 

 are thickh- placed and ferns grow under them. I suspect that they live 

 in the spruce, rather than in the roots of ferns, but have no reason for 

 this opinion. I captured a female in my stable, situated among the 

 spruces, boxed her, and a day after, on the 26th of July, she was kind 

 enough to lay several hundred eggs which I did not count. They were 

 fortunately fertilized, and the young hatched out from them a week or 

 two later; I did not make a note of the exact date. 



Egg. — The eggs are very peculiar in appearance, quite different 

 from those of any other moth. They are small, black, shining like 

 seeds. They are about one-half a millemeter in length, the diameter a 

 little less, as the eggs are cylindrical-spherical, slightly pointed at each 

 end. The shell is jet black, highly polished, and under a half-inch ob- 

 jective shows no traces of ornamentation. 



Freshly-hatched larva. — (PI. Ill, Fig. i.) Length 1.3 mm. 

 Head large, broad and flattened, somewhat wider than the body and 

 very pale chitinous. Prothoracic segment as wide as the head and with 

 a large dorsal chitinous plate of the same color as the head. The 2d 

 and 3d thoracic segments have no plates. The body is moderate!} 

 wide, a little flattened and pale whitish, with no markings, and gradu- 

 ally and slightly tapers toward the end. The spinneret is unusually 

 large and long, and the maxillce are rather large. The thoracic legs 

 are testaceous (chitinous), of the same hue as the head. The abdomi- 

 nal legs are rather long, pale. The hairs are arranged as in PI. Ill, 

 Fig. I to (A, part of the head, and tlie succeeding four segments; and B, 

 the last four abdominal segments) in the same way as in normal Tineid 

 and Tortricid larv?e ; the four dorsal hairs arising from minute warts 

 arranged in a low or short trapezoid ; the terminal segment bearing six 

 setae. The hairs or setae are about as long as the segments are broad, 

 becoming longer in proportion on the last segment. They taper to- 

 wards the end, not assuming the shape of the glandular hairs of the more 

 modern Lepidoptera. 



In the fully grown Hepialus larva the set^ are much reduced in 

 size and length. It may be of interest to state that some eggs of the 

 Australian Oncopera iiitricata Walk., kindly sent me by Mr. G. Lyell, jr., 

 are the same in size and appearance. The freshly hatched larvje are 

 also very similar to those of Hepialus vinsteliuus, the hairs and shape 

 and size of the body being nearly identical.
