dark portion of the wing; it is followed by a diffuse whitish band. Intradiscal line 

 formed by the ground color, geminate, the outer line bordering the inner edge of the 

 median fascia with which both are parallel. Inner portion of outer area occupied 

 by a broad band of ground color which is sometimes traversed through its center by a 

 pale brown line. Outer portion of area brownish, paler internally and somewhat 

 broken into anteriorly by the ground color. A white line passes through the center 

 from costa to internal angle. Terminal line deep brown, broken at the veins and in 

 the center of the cells. Discal spot large, black, oval. Secondaries with the lines 

 and shades of outer half of primaries faintly repeated from inner edge to center of 

 wing. Terminal line as in fore wings but somewhat scalloped. Discal spot present, 

 small. Beneath, pale luteous, the darker ornamentation of above reproduced in ochre. 

 Discal spots small on all wings but distinct. Terminal line as above. 



Types. — Two males from Mr. Frank Haimbach of Philadelphia, 

 one of which he has kindly allowed me to retain. 



Habitat. — Huachuca Mts., Arizona, in July (H. A. Koeber). 



This species has the general aspect of a Petrophora and approaches 

 Hydriomena mirabilata Grt. in style of markings, but is quite different 

 from that species both in general color and in the course of the trans- 

 verse lines. 



9. Coenocalpe delicata, new species. 



Expanse, 26-28 mm. Palpi brown ; head brown with deep carmine scales, 

 especially on the vertex ; thorax, except the patagia which are brown with mixed 

 carmine scales, and abdomen yellowish brown. Both wings pale translucent fuscous, 

 considerably darker on costal and apical areas of primaries and washed over with a 

 delicate pink hue, which in the darker portions shows as prominent carmine scales. 

 Costa of primaries marked by four large, white, quadrangular spots, the third from the 

 base lengthened longitudinally, the fourth continued in a broad line which crosses 

 the wing, extending in an even outward curve almost to center of wing, then almost 

 straight to inner margin. In this pale band the pink color shows up prominently 

 below the costal area. There is a vague indication of an oval discal spot. Fringe 

 brown, traversed by two fine pink lines. Secondaries evenly colored except at 

 extreme outer edge where it is brownish. Beneath, the pattern on the primaries 

 above is reproduced, the darker portions being still darker and more mixed with red 

 while the white is a little obscured. Secondaries much darker than above and heavily 

 suffused with reddish especially on outer half. There are two elongate, white marks, 

 heavily edged outward with brown a little beyond the middle of the wing, one be- 

 ginning on costa and extending in a straight line toward anal angle, the other com- 

 mencing on inner edge and running toward the apex. These if continued would 

 meet to form a single complete band, angled in the middle, but in none of the speci- 

 mens before me are the marks connected. Discal spot small, linear. 



Types. — Four males and five females in my own collection. 

 Co-types will be placed in Rutgers College collection. 

 Habitat. — Stockton, Utah, Sept. 12 (Spalding).
