of costa, some black scales before middle, and a slight oblique postmedial fascia from 

 costa, of darker yellow, scaled with black, and edged with white. A black tuft 

 in fold opposite this fascia. About five small black terminal dots, the apical largest. 

 Sometimes with a complete angulate white postmedial line. Male with hair pencil. 

 9mm. (abietiaella Packard). 



June and July. Caterpillar webbing needles of hemlock in early June. Green, 

 with blackish head and cervical shield. 



New Jersey to District of Columbia and Pennsylvania; probably more generally 

 distributed. New York: Wells. 



2. R. variella Chambers. Yellowish white, apical half of fore wings suffused with 

 golden yellow or dusted with brown; three or four distinct black dots at base of 

 costal fringe, which has some scattered black scales; occasionally with a couple 

 of fine streaks along costa. Costa sometimes wholly brown or golden. Sometimes 

 with a white angulated postmedial fascia broken at middle; a raised black tuft 

 on fold at three -fourths way to apex. Head, including inner side of palpi and 

 antennae, white. Outer side of palpi yellow. 8 mm. 



June and July. Caterpillar in a silk-lined tube between needles of bald cypress 

 and evidently other trees. Mississippi valley specimens are yellower than eastern 

 ones. 



Montclair, New Jersey and District of Columbia to Kentucky. New York: 

 Yonkers. 



3. R. coniferella Kearfott. Similar to R. apicitripunctella ; ground ochre, not lemon 

 yellow, and much mottled with white; antemeaial fascia nearly continuous as far 

 as fold, but all fasciae showing the tufts as partly or entirely separated dots. Apex 

 and fringe more heavily gray-dusted; second segment of palpus rather heavily scaled 

 with black, suggesting two fasciae. 



June. Larva on pine. 

 Ottawa; Ontario. 



4. R. piceaella Kearfott. Similar to R. apicitripunctella; dark, dusted with 

 fuscous on a straw-yellow ground; head straw yellow, concolorous with the ground.

 at the middle; normally a black dash in the terminal area, extending to the apex. 

 Hind wing dark gray. Abdomen with dark dorsal patches. 10 mm. 



Variety obscurella Kearfott (nigra Kearfott, not Busck), is suffused with blackish 

 except on the inner margin, and on the costa beyond the median fascia, where it 

 is powdery luteous; white postmedial fascia only, contrasting. Head luteous; the 

 face lightly and vertex heavily dusted with black. 



Caterpillar webbing and mining needles of red and black spruce. Red, with 

 light brown head and cervical shield and dark green dorsal segmental patches.! 

 Crimson ventral spots on thorax between legs, and on fifth and sixth segments 

 of abdomen. Moth in June. 



New Jersey. Apparently the same moth occurs in Ontario. 



5. R. thujaella Kearfott. Palpus with first segment black, second with a black 

 streak below and dusted with black, third white with two black bars. Head cream 

 white, paler than in R. piceaella. Fore wing cream-white, heavily dusted with 

 blackish, appearing fuscous gray; with three oblique blackish fasciae, the firsl 

 reaching to fold, the other two shorter; apical region darker, with blackish streak* 

 running out to the strong costal terminal dots. Tufts well marked, in three pairs, 

 black. Hind wing light gray. Abdomen cream-white. 9 mm. 



June. Caterpillar on Thuja, eating out the sprays from inside, in May. Head, 

 cervical shield, true legs, and anal plate black-brown; body dull red with greenisl 

 incisures, pinkish below.

 scape white in front. Fore wing powdery gray, with a curved black band fron
