No. i. BOMBYCINE MOTHS OF NORTH AMERICA— PACKARD. 131 



This is closely allied to the following species, and may prove to be not specifically distinct 

 therefrom. The present species comes from the southern end of the Mexican plateau, whereas 

 lex has been found some 600 miles farther north. Specimens from intermediate points are 

 needed to show the relationship of these forms. — Dyar, Proc. Ent. Soc, Wash., 1911.] 



HEMILEDCA LEX Druce. 



[Euleucophxvs lex Druce, Biol. Cent.-Am., Lep. Het., II, 420, 1897. 



Described from a single male from Durango City at the foot of the Sierra Madre. The 



species is not before me, but it is interesting to note the similarity in location with that of the 



allied olivise. Both species inhabit high, arid land on the eastern slope of a mountain range.—

HEMILEUCA SORORIA iH. Edwards). 



Plate LXIII, fig. 14. 



[Euleucophceus sororius H. Edwards, Papilio, I (1881), p. 100.] 



[The original description, based on a single female from La Paz, Lower California (Mexico), 

 is as follows: 



Primaries pale reddish brown, a little paler at the posterior margin. The lines are broad 

 white, the inner one oblique, not curved, and not reaching to the costa, the outer one slightly 

 waved about the center toward the posterior margin. In the median space, a little nearer to 

 the inner than the outer line, is an oblong discal mark of yellowish brown. The costa at the 

 base is brownish, in the median space it is necked with white scales, and at the apex it is white 

 from the junction of the exterior line. Fringe and internal margin whitish, with a pink tinge. 



Secondaries dull reddish brown, paler on the disk; the nervures very strong and distinct; 

 the fringes clear white. 



Beneath the wings are pale reddish brown, the bands of the primaries faintly exhibited. 



The fringes and the costal margin of secondaries clear white. Head red brown, orange 

 at the base of the antennae. Thorax red brown, with long grizzled hairs. Abdomen chestnut 

 brown, with broken whitish lateral bands. Antennae beneath and tarsi bright orange. Exp. 

 wings, 3 inch.] 



[Compared with H. olivise 9 , the primaries are more pointed at apex, inclined to be sub- 

 falcate; the discal mark is not so nearly at right angles to costa, but if prolonged to costa 

 would make an acute angle on inner side; the outer pale band has a double curve.] 



HEMILEUCA MEXICANA Druce. 



[Metanastria mexicana Druce, Biol. Cent.-Axn., Lep. Het., I, 201, 1887. 

 Dendrolimus mexicana Kirby, Cat. Lep. Het., I, 816, 1892. 



This species was described as a lasiocampid, but, although no specimens are before me, it 



is evident from Druce's apparently excellent figures that it is a member of this genus. The 



species was described from two specimens in the collection of the late Dr. Stau dinger, and are 



without exact locality. It seems doubtful whether the two sexes are correctly associated. 



The c? is represented with a dark discal mark, the $ with a pale one, and there are other 



differences that would not be expected in sexes of one species. — Dyar, Proc. Ent. Soc. Wash., 



1911, p. 10.] 



HEMHEUCA [PACKARDI n. sp.]. 



Plate LII, fig. 9. 



Imago. — Antennae with the joints shorter than thick; the outer pectinations about four 

 times as long as the inner, which are tooth-like on the basal half, but beyond the middle 

 nearly as long as the outer ones. 



Thorax and wings of a beautiful delicate rose-carmine; the wings thin. Head dull ochreous 

 in front. Thorax lake color, with pale gray hairs longer than the others. Fore wings uniform 

 pale delicate lake, becoming at the base of the wings a little deeper in tone; they are crossed
