Xylophasia ciuefacta Grt. 

 18bl. Grt., Papilio i, 77, Hadena. 



Ash gray, pale, powdery ; more or less suffused with luteons, most 

 evidently so in the median space; terminal space darker. Basal line 

 obsoletely indicated. T. a. indistinctly geminate, strongly angulate in 

 submediau space, and somewhat confused and indefinite to the hind 

 margin. The basal space is strongly white-powdered. T. p. line nearly 

 parallel with outer margin, slightly produced on the veins. S. t. line 

 pale, incomplete, with the usual W mark ; through the middle of the 

 wing preceded by a dusky interrupted shade. The s. t. space is pale, 

 the veins flecked with black scales. A black basal streak. Claviforra 

 usually extending nearly across the median space, a dark shade line 

 completing the connection. Orbicular elongate, oblique, sometimes 

 confluent, with the upright reniform. A faint median shade crosses be- 

 tween the spots, sometimes darkening the outer portion of median 

 space. Secondaries fusco-luteous, paler toward base. Beneath, pale, 

 powdery, with somewhat indefinite outer line and discal spot. Head 

 and thorax concolorous, collar and patagine with black line. 



Expands 35 to 40 millimetres, 1.40 to 1.60 inches. 



Habitat. — Washington, California, Colorado. 



The specimens from Colorado differ in lacking all yellow shade, but 

 not in structure or maculation so far as observable. I have seen no 

 specimens from Washington. The type from Mr. Edwards's collection 

 is marked "So. Calif." 



Xylophasia centralis Smith, sp. nov. 



General color of head, thorax, and primaries whitish with a variable 

 tinting of luteous. Collar with a central black line, patagioe black 

 margined. Primaries with a narrow black basal streak below median 

 vein and another along internal margin. Along costa and inner margin 

 the pale basal space is slightly clouded. Basal line geminate, indis- 

 tinct. T. a. line geminate, outer part distinct, black, inner vague, 

 powdery ; the line outwardly oblique, slightly curved, somewhat irreg- 

 ular, but nowhere dentate or angulate. T. p. line as a whole almost 

 parallel with outer margin after the usual bend over reniform ; gem- 

 inate, outer line not distinct, inner line but slightly crenulate over reni- 

 form, else even. A distinct, broad median shade from cosca between the 

 ordinary spots outwardly oblique to vein 2, there angulate and then 

 parallel with and close to t. p. line to inner margin. S. t. line white, 

 irregular, the W mark prominent, preceded by two distinct black sag- 

 ittate marks. The line is preceded by a luteo-fuscous shade, variably 

 distinct, the s. t. space else whitish. A row of black terminal lunules, 

 fringes cut with white. Terminal space, except apical patch, dusky. 

 Median space dusky, with a slight fuscous tinge. Orbicular oval, com- 

 plete, oblique, concolorous, with a darker fuscous central spot. Reni- 

 form large, broad, upright, somewhat dilated inferiorly, pale marked, the
