NORTH AMERICAN LEPIDOPTERA. 57 



Three very strongly dissimilar specimens, all females. The spe- 

 cies is most nearly allied to idahoetisis, differing principally in the 

 very distinct shade containing still darker sagittate spots preceding 

 the s. t. line, which is less dentate than in its ally. The variations 

 have been indicated in the description. The structural characters 

 are of the iessellata group. 



Agr4>tJ!!$ iiifelix sp. uov. — General color red-brown, varying in shade. 

 Head and collar inferiorly either Ki'ay or yellow, with a ferruginous aiiniixture, 

 contrasting; a black transverse line across the middle of the collar limits the 

 pale space superiorly, and above this line the collar is concoiorous with thorax. 

 Thoracic disc in the specimen even, concoiorous; in another the entire color is 

 diarker, the tuftings are gray tipped, the patagiae with gray powderings and 

 margined with black. Primaries with costal region discolored yellow, with a 

 ferruginous or an ash gray powdering, gradually merging into the ground color 

 before the inception of the t. p. line. Basal line whiti.sh, loop-like, cutting a 

 disk out of the basal black streak. T. a. line visible only in the s. t. interspace, 

 where it crosses the black basal dash in the form of an outcurved pale line mar- 

 gined with deep black. T. p. line narrow, single, finely creuulated, slightly 

 outcurved over reniform. thence very evenly parallel with the outer margin. 

 This in the ^\ in the % no trace of the line is visible. In the % the color is 

 even unbroken through the median and s. t. space to the s. t. line, whicli arisps 

 from a gray apical spot and is punctiform and very slightly irregular, the .spots 

 preceded by sagittate black dashes; beyond this line the narrow terminal space 

 is slightly more dusky, and there is a row of small black terminal dots: in the 

 9 a grayish suflfusion along the black marked veins relieves and lightens the 

 s. t. space, intensifies the black sagittate dashes and makes the terminal space 

 darker by contrast; the maculation, otherwise, is as in the %, save that the s. 

 t. line is more evident and some of the spots are connected, showing that the 

 line is distinctly dentate on veins 3 and 4. Claviform distinctly black margined, 

 variable in size and form, center concoiorous, surmounted with an also variable 

 pale, yellowish streak, crossing the median space. Orbicular oval, oblique, com- 

 plete, black ringed, then with a pale annulus, centre of the color of costal re- 

 gion : reniform large, kidney shaped, contrasting yellowish, inferiorly dark 

 grayish marked. In the 9 the entire internal margin is gray marked. Secon- 

 daries evenly fuscous, with a row of terminal darker lunules, fringes paler. 

 Expands 1.65 — 1.80 inches; 41 — 45 mm. 



Habitat. — California (Neumoegen). 



This handsome and well marked species comes nearest to ohelis- 

 eoides in the tessellata group, but is perhaps more nearly allied to 

 perexcellens of the qudridetdata group. From the latter it is distinct 

 by the lack of the prominent dentations of the s. t. line ; from the 

 former by its very much larger size, the more produced primaries, 

 different s. t. line and other details of maculation. The line of va-
