22. OlDAEMATOPHORUS niOEBUS n. sp. PI. XLVI, fig. 5. PI. LII, 



fig. 15. 



Head brown with a whitish band between antennae. Antennae faintly 

 brown-dotted above. Palpi small, oblique, whitish with traces of brown on 

 third joint. Thorax whitish in front, becoming tawny to brownish behind. 

 Fore and middle legs infuscated, white outside, without tufts. Hind legs whitish 

 to pale gray brown in the darkest specimen at hand, spurs moderate. Abdomen 

 apparently concolorous with posterior part of thorax, with a variable number 

 of single dark gray-brown dorsal dots on posterior margins of segments. 



Primaries whitish to light tawny brown, the palest area in the second lobe 

 and along inner margin of first. Costa whitish toward base, sprinkled with 

 blackish scales, otherwise immaculate, paler toward apex. Cleft preceded at 

 a short distance by a faint dark dot. Entire wing usually with some scattered 

 black scales, less numerous on the disk and tending to form streaks in the lobes 

 and near the inner margin. Fringes pale on costa, elsewhere brownish gray to 

 brownish black, contrastingly darker than wing. Secondaries brownish gray 

 with concolorous or slightly darker fringes. Expanse 21-23 mm. 



Described from four specimens as follows : 



Holotype S, Carmel, Cal., June 10 (Williams), paratype ?, Carmel, Cal., 

 Apr. (Vachell) and paratype ?, Deer Park Springs, Lake Tahoe, Cal., July 

 8-15, coll. Barnes. Paratype ?, San Luis Obispo, Cal, Mar. (Vachell), U. S. 

 N. M. No. 23473. The abdomens of all the paratypes are broken. With these 

 specimens we associate one 9 from Palmerlee, Ariz., and one from Westmin- 

 ster, B. C. The latter is our palest specimen, but we see no reason to doubt 

 that it belongs here. 



23. OlDAEMATOPHORUS TRITON n. sp. PI. XLVI, fig. 4. 



Head brown with a whitish patch between antennae. Antennae whitish ; 

 palpi small, oblique ; third joint touched with blackish on outside. Thorax 

 whitish. Abdomen light brown in the types, but this is apparently due to the 

 usual discoloration. In the holotype there seems to be a trace of dorsal brown 

 spots. Vestiture roughened on posterior margins of segments. Legs whitish, 

 fore and middle pair infuscated within. Spurs of hind pair moderately long. 

 Tibial tufts absent. 



Primaries white suffused with light gray lirown excepting a band around 

 base of cleft and along inner margin of first lobe, and a variably extensive 

 area along inner margin to apex of second lobe. Disk with a faint whitish 

 streak leading basad from cleft and a faint subcostal whitish line, meeting 

 costa just before base of cleft. Before and beyond this point the costa is darker. 

 Cell with a small dark spot at middle, sometimes absent. Before white band 

 at base of cleft there may be either one, two or no spots, if tv.o the inner is 

 darker. First lobe with a dark dot before apex on inner margin; second with 

 a dot or dash at apex and three dashes on tips of preceding veins. In this 

 lobe the gray-brown suffusion sometimes marks the veins for a short distance. 

 Fringes on costa white with a few grayish scales, elsewhere brownish gray,
