8 and ll a little larger than the others. Side horns short, sessile, wider than long, 

 those of Joints 3 and 4 a little longer than those of 6 to 12. Cal trope patches on the 

 horns of joints 6 lo 12 and on the base of the subdorsal horn of joint 13, large on 

 joints 12 and 13, then progressively smaller till the horns of joints 6 and 7 have only 

 a few or no caltropes. Skin finely clear granular except on the horns. No end 

 spines. Dorsum yellow or red shaded, a purple band with white glandular dots and 

 central dorsal line much as in spinttloides but of different shape. It widens between 

 joints 3 and 4, 4 and 5, then moderately widens on joints 6 and 7, narrows to a slight 

 bordering of the white dorsal line over joint 8, widens behind the horns on 9 and 10, 

 moderately, widens between joints 11 and 12 and ends, joint 13 being green above. 

 A bright red, diffuse, subdorsal band ; all the subdorsal horns red. Below a yellow 

 stripe, narrowly red edged, waved. Sides green, a row of yellow dashes along the 

 lateral horns, green edged above ; yellow rings on spaces (4). A white line along 

 the subventral edge. Stinging spines short, not numerous. Depressed spaces ( i ) 

 and (2) represented by white dots, (l) paired and on joints 3-4 and 4-5 also double ; 

 depressed space (4) reniform, distinct; slight hollows subventrally ; spiracle of joint 

 5 moved up out of line. 



A NEW SPECIES OF ETHMIA FROM THE 

 BOREAL REGION OF COLORADO. 



By August Busck, 

 Washington, D. C. 



Ethmia caliginosella, new species. 



Labial palpi long, recurved ; second joint somewhat loosely scaled on the under- 

 side, terminal joint short ; both joints black. Face, head and thorax black. Fore 

 wings dark slaty gray with a black longitudinal streak on the fold from back to be- 

 yond middle of wing and another black longitudinal line from the middle to the end 

 of the cell. This latter streak is dilated at the end of the cell into a circular black 

 discal spot from which radiate a few indistinct and interrupted narrow black lines 

 along the apical veins. Around the apical edge is a conspicuous row of black dots. 



Hind wings dark slaty gray with a very narrow black line around the edge before 

 the cilia. Abdomen black with the exception of the three last and part of the fourth 

 .segments, which are bright orange-yellow. All legs blackish. Expanse, 23 mm. 



One 9 specimen, Silverton, Colorado, 12,000 feet altitude (C. P. 

 Gillette). 



Type. — No. 7733, U. S. National Museum. 



Nearest and quite close to Ethmia monticola Wals., described from 

 Oregon. (Proc. zool. soc. Lond., 1880, p. 87, Plate XII, Fig. 3); 

 easily distinguished, however, from this species by its smaller size, its 

 darker head and body, its black posterior legs, smaller yellow area of 

 the abdomen and by minor differences in the pattern of the wing.
