Expands : .85-. 90 inch = 21-22 mm. 



Habitat. — -Santa Catalina Mts. , April 8-15; southern Arizona, 

 May 15. 



Two males from Dr. Barnes, one female from Mr. Poling ; one of 

 the males defective, yet representative in maculation. The leaden 

 gray primaries with the acute outward indentation in the cell is 

 characteristic. 



Conochares interruptus, new species. 



Mead, thorax and basal half of primaries white, immaculate. Beyond the ter- 

 mination of the white area, at or a little beyond the middle of the wing, the surface 

 is mottled with olivaceous gray, a little tinged with yellowish in some examples. The 

 margin between the white and gray is sharply delined by a blackish gray line which 

 diffuses outwardly, is oblique in general course, and is usually interrupted opposite 

 reniform, the white extending to that spot which is round, gray, and ringed with 

 white. The s. t. space is more or less mottled with gray and white, the pale s. t. 

 line being always well-defined and a little sinuated. Terminal space gray or mottled. 

 A series of small black terminal dots in some specimens. Fringes white, interrupted 

 by a gray shading opposite cell and sometimes by another at hind angle. Second- 

 aries slightly infuscated, darker outwardly. Beneath, primaries dull yellowish to 

 smoky, secondaries white. 



Expands: .80-. 87 inches = 20-22 mm. 



Habitat — Southern Arizona, April 10, Poling ; Phoenix, Arizona, 

 March 12, Griffith; Yuma County, Arizona, in March, Hutson ; 

 Argus Mts., California, April, Koebele ; Walters Station, California, 

 April, Hutson. 



One male and seven females, most of them in rather good condi- 

 tion. Eive scattered localities for eight examples, taken by four col- 

 lectors, argues rather a rare species ; but I believe it will be found not 

 uncommon when carefully sought for. As compared with acutus, 

 this species is a little smaller, the outer half of wing is distinctly more 

 motded and with a luteous shading, the dividing line between colors 

 is very even and the fringes are interrupted by gray shadings. 



Acontia dimidata, new species. 



Head, collar, and anterior portion of thorax gray ; remainder of thorax white ; 

 abdomen whitish. Primaries white to the middle, where the space is sharply limited 

 by a blackish gray shading which is a little curved and somewhat irregular at the 

 edge. Toward base, the white is irregularly interrupted by gray shadings on the 

 costal region. In the dark portion of the wing there is a mottling of black and 

 whitish scales, and with a lens the maculation can be picked out ; but there is 

 nothing clear except a white edging just before the fringes which are based by black 

 scales. Orbicular wanting, reniform barely indicated. Secondaries a little dusky. 

 Beneath whitish.
