SPRUCE WORMS. 851 



Mofh. — Head cream-white ; antennae with the basal (second) joint white, beyond 

 ringed with white and black. Palpi white, first and second joint speckled with 

 black, second (longest) joint ocherous at the end ; third (last) joint with two black 

 rings of unequal size, the outer the longer; the tip white. Fore wings moderately- 

 wide, oblong ovate. Ground color ocherous whitish gray ; costal region blackish, 

 base black. A broad oblique band proceeds from the costal edge to the middle of the 

 submedian space, ending in two white spots; there are some whitish scales on the 

 outer edge of the band. Just before the middle of the wing is a broad irregular black 

 band, and beyond it in the submedian space a black spot. A third broad black band 

 crosses the wing, ending on the hind margin and breaking up into three black spots 

 on the hind margin ; the band incloses near them two twinned white dots. Near the 

 outer fourth of the wing is a conspicuous white line, sharply bent outwards just be- 

 hind the middle of the wing; beyond the apex of the angle of the line are several 

 white scales. At the base of the Iringe is an oblique line of black scales. The fringe, 

 like the adjoining part of the wing, is of mixed gray ocherous, with black scales. 

 Hind wings rather broad, pointed, pearly slate gray. Legs, including tarsi, banded 

 with black. Expanse of wings, 13™™. 



When rubbed the green color of the fore wings becomes paler, and the three oblique 

 black bands are more distinct. 



32. The spruce plume-moth. 

 Oxyptilus nigrociliatus Zeller. 



The chrysalis of this Plume-inoth was beaten from the branches of the 

 spruce June 23, at Brunswick, Me., under such circumstances as to lead 

 me to believe that the larva feeds on this tree. In Europe no mem- 

 ber of the family to which it belongs (Pterophoridw) is stated, so far as we 

 have been able to ascertain, to feed on coniferous trees, so it is worthy 

 of mention, though too infrequent to be of much significance. The 

 moth issued July 10, and has been named for me by Professor Feruald. 



The larval skin occurred with the chrysalis ; the head is of the nor- 

 mal form, pale in color, while the cast skin showed that the body was 

 covered with long, dense hairs. 



Pupa. — Like that of Pi. periscelidactylua, the thorax being obliquely truncated, and 

 the body somewhat compressed. Thorax in front with six pairs of long, curved, 

 stiff hairs, those of the abdomen in two dorsal rows of five pairs, and a lateral row 

 of short, stout spines ; from each of the dorsal spines radiate four slender hairs ; from 

 the spines of the lateral row arise two hairs which are curled and parallel with the 

 longitudinal axis of the body. The wings extend to near the middle of the sixth ab- 

 dominal segment. Color, pale green ; wings and body whitish green. Length, 7™™. 



Moth. — Uniform dark brown, fore wings forked with four white costal spots, the 

 third the largest and widest, the fourth linear, oblique, and extending on the second 

 or hinder division of the wing ; the latter with a white spot near the base. Scallops 

 of the fringe white, a black patch at the internal angle ; hinder edge of the wing 

 white, apex blackish. Expanse of wings, 16™™. 



33. Lophyrua abietia Harris. 



This species is common on the spruce. From July 1-30, 1884, it was 

 abundant, spinning its cocoon July 30. Following is a description of 

 the larvfe we found : 



iarra.— Head black ; eight pairs of abdominal legs ; body dark green, the color of 

 a fir leaf; no median dark stripe ; a broad lateral conspicuous dark stripe, and below 

 a second dark broken stripe along the lateral ridge.
