NORTH AMERICAN LEPIDOPTERA. 53 



Two male specimens are before me, differing quite markedly in 

 size and also in distinctness of the maculaticjn ; otherwise alike. The 

 picture was made from the specimen showing the greater contrast. 

 This species is fully congeneric with A. rUjida, having like it a well- 

 marked clypeal i)rotuberance and heavily arined fore tibiie. The 

 male antennie have the joints very slightly serrated and laterally 

 bristled. 



Though I feel that rigida and incognita cannot remain a.ssociated 

 with the other species of Agrotiph'da, they yet resemble them so 

 closely that no great injury will be done by refraining from creating 

 a new genus for their reception until additional material enables us 

 to make a more complete study of the specimens. The new si)ecies 

 differs obviously from rigida in the ground color, in the course of 

 the median lines, and finally in the color of the secondaries. 



Agrotipliila maculate n. sp. (PI. ii, fig. 7) — Colors black and wliitisb 

 gray, contrasting. Head laterally gray with a yellowish tinge, front blackish. 

 Collar gray basally and at tip ; patagisc gray margined, dorsum with much of 

 the vcstiture gray tipped, else black. Primaries with gray as the base, powdered 

 with black and all the markings black. The median space is more densely pow- 

 dered than the other pale jiarts of the wing. Basal line broad and distinct, dif- 

 fuse inwardly, darkening the extreme base of the wing. T. a. line interrupted, 

 broken ou the costa, so that the black spot preceding the orbicular appears to be 

 part of it, making the line seem inwardly angulate at the middle. A dusky 

 shade through the basal space along the hind margin. T. p. line outcurved over 

 the cell and slightly incurved below, single, outwardly toothed on the veins, 

 though scarcely lunulate. S. t. line marked by a preceding black shade, form- 

 ing a distinct, square patch on the costa, and more or less interrupted below. In 

 one specimen it is a continuous broad shade, in the other it is broken into spots ; 

 fringes gray. Claviform small, incomjjletely black margined; cell filled witli 

 black before, between and beyond the ordinary spots, whicli are of the light gray 

 ground color and are not otherwise defined. Orbicular moderate, oval, oblique, 

 open to the costa. Eeniform upright, moderate iu size, the inner margin straight, 

 the outer somewhat indented at the middle. Secondaries smoky black, the 

 fringes yellowish white. Beneath, whitish, powdery, with a discal lunule, extra 

 median and broken terminal Hue on all wings. Expands 31-32 mm.; 1.24-1.28 

 inches.

 7000 feet; Bean, Nos. 461, 493. 



Two male specimens in fair condition. The antennje are ciliated, 

 the joints scarcely marked, and the front is smooth. The species, 

 therefore, belong to the typical section of the genus, differing from 

 the other described forms by the blotchy maculation and distinctly 

 anartiform habitus. The two specimens before me differ in the shade
