the s. t. line almost to the outer margin. A series of blackish terminal lunules at the 

 base of the broad fringes. Claviform outlined in brown, concolorous, moderate in 

 size, a somewhat darker shading extending across the median space at this point. 

 O^'bicular oblong, oblique, somewhat irregu'ar, hardly defined, more or less powdered 

 with bluish white. Reniform moderate or rather small, narrowly kidney-shaped, 

 very narrowly and incompletely ringed with brown, annulate with bluish white, more 

 or less whitish powdered superiorly and a little dark shaded inferiorly, neither of the 

 spots at all prominent. Secondaries in the male whitish with an indefinite smoky 

 outer margin, in the J darker throughout, and with a yellowish tinge. Beneath 

 whitish, powdery, 9 darker, more smoky, primaries more powdered than secondaries, 

 both wings with a vague discal spot. Expanse, 32-35 mm. = I.28-I.40 inches. 



habitat: Los Angeles, California. 



Three examples, r $ , 2 9 9 ; the ^ from Mr. Coquillett (Coll. 

 U. S. N. M.), the others of uncertain source. The species is quite dis- 

 tinctive in appearance, the pale s. t. space, with its distinct W mark 

 somewhat recalling Mamcstfa liquida. But the naked eyes and 

 lengthily pectinated $ antennae dispel the illusion at once. 

 Cobalos franciscanus, sp. nov. 



Ground color rich fawn brown without contrasts except in the s. t. space of 

 primaries. Head and thorax concolorous. Primaries with the median space some- 

 what deeper in tint, the t. p. line prominently white-shaded below vein 3. Basal 

 line not obvious. T. a. line vague, brown, apparently simple, as a whole upright or 

 a little outcurved, a small outward angle in the sub-median interspace. T. p. line 

 brown, geminate on costa, else single, crenulate and outcurved over the cell, then 

 even, with a regular incurve to vein I, where it has a little outward tooth. S. t. space 

 in costal region of ground color, below that paler along the t. p. line until, below vein 

 4, the latter is white shaded, the shade broadest in the sub-median interspace and 

 forming the most prominent ornamental feature. Outwardly the space shades into a 

 reddish brown border to the s. t. line which is narrow, pale, irregular and very poorly 

 defined. On vein 3 a pale ray extends almosj to the outer margin cutting through and 

 not indenting the s. t. line. There is a series of brown terminal lunules, and the 

 fringes have a pale line at base. None of the usual spots are defined. Claviform 

 and orbicular are scarcely even indicated, reniform traceable in narrow, incomplete 

 outline and by a dusky filling. Secondaries uniform smoky brown, a darker ter- 

 minal line at the base of the paler fringes. Beneath very pale reddish gray powdery, 

 primaries with a discal spot and a feeble reproduction of the t. p. line of upper side, 

 secondaries with a dusky discal spot and no outer line. Expanse, 28 mm. = 1.12 

 inches. 



Habitat: San Francisco County, California, a single $ specimen 

 only, with the vestiture a little marred in spreading. This is a smaller 

 species than angelicus with proportionately shorter, broader wings, 

 more robust thorax, shorter antennae, tho equally pectinated and de- 

 cidedly darker colors. The maculation is practically all lost except 

 for the pale shading in the s. t. space and the prominent white margin
