new North- American Insects. 403 



X. — Two neio Case-hearing Lepidoptera. 



Coleophora siicedicola, sp. n. 



Expanse about 8 millim. 



Head, thorax, abdomen, legs, and primaries white; second- 

 aries and all the fringes verj pale ochreous. Primaries 

 without streaks or lines, but conspicuouslj, though irregu- 

 larly, speckled with black scales. Palpi clothed with white 

 scales, but the penultimate segment on the outer side with a 

 distinct black streak, running up to the small but well-formed 

 apical tuft. Antennae ringed with black and white, the ex- 

 treme base rather thickly clothed with wiiite scales. 



Case about 5 millim. long and 1 broad, cigar-shaped, dark 

 brown, roughened, the mouth like that of a Clausiiia shell ; 

 hind end tricarinate. 



Hah. Common on Suceda at Mesilla Park, New Mexico 

 {CML). !Moths emerging at the middle of August. 



1 will take this opportunity to mention that Lyccena exilis 

 breeds in numbers on the same Suceda plants ; this is quite a 

 new food-plant for it. 



Coleophora atripltcivora, sp. n. 



Expanse 18 millim. 



Head and thorax above and primaries white, with a delicate 

 ochreous tint. Secondaries, abdomen, legs, and underparts 

 of body silvery white ; hind tibia? pale ochreous, clothed with 

 long white hair. Fringes pale, faintly greyish, tinged with 

 ochreous ; fringe on primaries at its longest longer than the 

 greatest diameter of the wing. Primaries apparently without 

 streaks, but a close examination shows that the courses of 

 the veins are broadly ochreous-tinged, while the intervals are 

 narrowly white, producing an obscure longitudinal streaking, 

 which is somewhat intensified by the fact that the intervals 

 are peppered with minute dark grey specks. Palpi quite 

 long, the penultimate segment with a well-marked terminal 

 brush of scales. Antenna delicately annulate with white and 

 pale grey, the basal two fifths heavily clothed (especially 

 above) with ochry-white scales, so as to appear considerably 

 thickened. Abdominal segments 2 to 6 each with a pair of 

 longitudinal narrow brown («'. e. scaleless) marks, one on each 

 side of the median line. 



Case cigar-shaped, 12 millim. long, 3 broad; white, with 

 the faintest yellowish tinge, roughened, tricarinate at hind
