This common ami widely distributed species hardly needs detailed 

 description. The deep red of median space, contrasting s. t. space', and 

 dark terminal space are characteristic. Western specimens as a rule 

 run much paler than those from the East. Its life history has been 

 written in economic publications. 



Xylophasia albina Grt. 



1874. Grt., Buff. Bull, ii, 157, Hadena. 



1881. Grt., Bull. U. S. Geol. Surv. vi, 263, a var. castanea. 



Luteous or rusty brown, often darker, sometimes with a more car- 

 mine sufiusion. Beyond the reniform the wing is paler, more yellowish, 

 and opposite internal angle there is a bluish-white patch beyond t. 

 p. line. Basal line geminate, distinct; t. a. line geminate, outwardly 

 curved between veins. T. p. line geminate, iuterior line darker; out- 

 wardly bent over cell, and marked on veins, strongly incurved in sub- 

 median interspace. S. t. line broad, of pale ground color, marked by a 

 continuous brown preceding shade and the darker terminal space, 

 its course irregularly sinuate, forming a distinct though not promi- 

 nent W on veins three and four. A row of black terminal dots. Basal 

 space often with a paler yellowish shade. Claviform large, concolorous, 

 black ringed, extending nearly across the median space. Orbicular 

 slightly paler, large, oval, oblique. Reniform large, upright, strongly 

 white marked— always with at least a white center. Secondaries pale 

 ochery fuscous with broad dark outer border, an inner dut^ky line and 

 discal lunule. Beneath reddish powderj-, with outer dusky line and 

 lunule. Dorsal tufts of thorax pale, somewhat discolorous ; basal tufts 

 trilobed, prominent; abdominal tnftings prominent. 



Expands 44 to 48 millimetres, 1.75 to 1.90 inches. 



Habitat.— California. 



Closely allied to arctica^ but sufficiently distinct by the entirely differ- 

 ent ground color, and characters elsewhere pointed out.

Dark smoky brown, s. t. space hardly paler; termina. space darker. 

 Basal line geminate, black. T. a. line geminate, blackish, outwardly 

 bent, and somewhat indented on the veins. T. p. line geminate, outer 

 line obsolete, its course nearly as in the preceding specii'S. S. t. line 

 yellowish, rather evenly sinuate, sometimes interrupted. A series of 

 small black terminal dots. A fairly distinct median shade line from 

 costa between ordinary spots and then close to and parallel with t. p. 

 line to JDner margin. Claviform moderate, concolorous, narrowly
