markings much as in manti Barnes, except that the lines appear 

 dark on a paler ground. Their course, however, is the same. 



Stibadium crenulosum, new species. 



Fore wing with the median and terminal spaces blackish brown, 

 extreme base and subtcrminal space light reddish-brown; inner line 

 visible below the cell as long lunules between the veins; outer line 

 crenulate, irregularly doubled ; a few brown streaks in the pale sub- 

 terminal space ; reniform whitish with a curved central dark bar. 

 Hind wing fuscous shaded, especially subterminally, the fringe pale. 

 Expanse, 24 mm. 



One specimen, Tehuacan, Mexico, September, 1908, from 

 Mr. R. Miiller. 



Type No. 12224, U. S. Nat. Mus. 



The species has the size and aspect of narinni Harvey, but 

 the dark shadings are blacker and not powdery, while the 

 terminal space is sharply discolorous ; the inner line is obscure, 

 but strongly toothed. 



Stibadium concinnum, new species. 



Fore wing olivaceous gray, powdery, the ground color lighter along 

 the outer line and around the orbicular ; basal space uniform ; inner line 

 white, narrow, evenly arculate ; orbicular large, round, black-filled, 

 narrowly white-edged ; reniform dark-filled, but scarcely darker than 

 the surrounding area, narrowly white-outlined, constricted ; outer line 

 narrow, white, angled at vein 6, a black costal patch above the angle, 

 subterminal line white, powdery, .with a distinct black inner edge, 

 becoming broader towards the inner margin and obscurely cut by the 

 veins ; fringe with a narrow white line at the base. Hind wing whitish, 

 with a faintly indicated outer line, the terminal space gray-shaded; a 

 grayish discal bar; fringe dark, with a white line at the base. Expanse, 

 30 mm. 



Two specimens, Tehuacan, Mexico, September, 1908, from 

 Mr. R. Miiller. 



Type No. 12225, U. S. Nat. Mus. 



The species is allied to curiosnm Neumoegen and pityochro- 

 in us Grote, but is more contrastingly and neatly marked than 

 either. The dark border to the submarginal line is somewhat 

 as in triplagiatus Smith, but more extended and also broken by 

 the veins. 



Stibadium curiosum 



Mr. Miiller sends a specimen from Tehuacan, Mexico, darker 



than the ordinary form. A blackish shading from the base
