12 GROTE AND ROBINSON. 



most distinct on coata, fading towards internal margin, before which it 

 becomes obsolete. No discal spots on either surface. In shape the 

 Mocondaries are as in A. bicolor. 



Expamc, 9 , 2.85 inch. Length of body^ 1.10 inch. 



Habitat. — Mexico. 



Is at once distinguished from 9 ^- bicolor, by the distinct lines of 

 the upper surface of primaries and simple antenuse.

9 . Head and collar, whitish ; beneath, the compressed palpi, the 

 under thoracic parts and inside of the legs are deep obscure ochraceous. 

 Outwardly, the legs are palely colored and everywhere sparsely and 

 finely irrorate with blackish scales. Thorax, above, loosely haired, 

 pale, dull whitish fiwn color; the scales anteriorly, from beneath the 

 'collar," are darker tinged. Abdomen, hardly as long as internal 

 margin of secondaries, pale ochraceous, irrorate with black scales and 

 with diffuse sementary pale shades continued entirely around. Antennte, 

 moderate; the stem, above, is covered with pale scales, beneath it is 

 brownish, with a double row of reduced pectinations. 



Wings shaped as in P. syriiigaria. Costa of primaries sinuous; 

 n^ndedly produced at base, depressed before the truncated apices. 

 Kxternal margin produced medially, sub-excavate between the nervules. 

 Dull fawn color with bright ochraceous and whitish shades, sparsely 

 and rather coarsely irrorate. At extreme base the costal region is 

 bright ochraceous, mottled with ferruginous transverse streaks, form- 

 ing a distinct blotch. Below the median nervure, from the base to the 

 third transverse band, the wino: is dull fawn color. Costal region more 

 whitish than elsewhere. Three deep brown transverse irregular bands 

 cross the wing from costa to internal margin. The.se are very broadly 

 marked on costal region, below which they are linear, the first and se- 

 cond slightly diffuse. The first is angulated outwardly on median ner- 

 vure. The second, at the middle of the wing, is somewhat flexuous 

 or sinuate. The third band follows the second, at a nearer distance 

 than the second does the first ; this is distinct and linear, less heavily 

 marked on costa than the others, rouuded outwardly to median ner- 

 vure, where it is bent inwardly, thence running straightly to internal 

 juargin. At extreaiity of the discal cell, between the second and third 

 t-ransversc bands, the wing is suffused with bright ochraceous. A
