MEMOIRS OF THE NATIONAL ACADEMY OF SCIENCES. 187 



Mr. (iraef's specimens* were received from Texas. He remarks: "I received more than a 

 dozen specimens from Texas, and they are all of this form and constant: //. aurora is a totally' 

 different sjiecies."" I took it for granted that this form was distinct from aurora, but renewed 

 examination makes me inclined to regard it as a variety. 



Mrs. Slosson, who tells me she lias seen in Florida lumdreds of the normal If. aurora, thinks 

 this variety is distinct. The following description of II. peroplioroidcs is drawn up from eight i and 

 one 9 in ber collection. In life ]\Irs. Slosson has uoticed that the thorax is bathed with a glaucous 

 green tinge, which exten<ls to the base of the fore wings, but di sappears as the moth dies. Antenns* 

 plumose. Head in front and markings ou the wing rich pale wine-red; head above, thorax, and 

 ground color of the -wings fawn-browu. Fore wings uniformly fawn-brown, two deeply staine<l, 

 wine-red, narrow, distinct transverse lines, nearly parallel, passing from the inner side of the wing- 

 to the costal edge, and a third concolorous line starting from the junction of the median vein and 

 the inner line and ending on the costal edge nearly halfway from base of wing to the end of the 

 line it joins. (These lines are situated exactly as in the normal examples of H. aurora.) Hind wings 

 suffused with pale wine-red on the outer fourth. 



In two c? the entire fore wings are uniformly suffused with pale claret-red, and in one <5 the 

 -wings are suffused »\ ith the same tint, but the space between the three lines are deep, dull, wine, brick 

 red, like the lines themselves, the band being about twice as broad on the costal as on the hind edge. 



Underside : Fore wings deep wine-red, paler along the outer margin : hind wings whitish, with 

 reddish scales on the costal edge.

Moth. — ''Head yellowish with rose center; antenna' light brown: eyes black; collar, thorax, 

 patagia, as well as jirimaries, of beautiful light rose color; nerves concolorous: fringes whitish. 

 Beyond median cell, from costa to inner margin, a transverse white line, slightly bending 

 inwardly at its center. 



"Secondaries and nerves white, with a rose-colored marginal line along costa and margin to 

 anal angle. A rose tint along anterior margin, fading toward center. 



"Abdomen yellowish-white, with rose anal tuft. 



"Below, primaries and secondaries of yellowish white, with concolorous nerves and fringes. 

 Costa rose and broad marginal rose tints, especially so ou primaries, fading toward center. 



"Legs rose colored; prominent yellowish- white tibial spines. 



"Expanse of wings, 30 mm.; length of body, 9 mm. 



"Habitat: Colorado. Type, 3 , Coll. B. Neumoegen. 



"It seems to be a rare species, for Mr. Bruce only caught one last year, and this summer 

 only five specimens, among which one 9 , which, as he writes me, tallies in all details with the S . 

 Its name is warranted by its beauty."

"Primaries twice as long as broad; costa almost straight, very slightly concave about the 

 middle ; apex pointed ; outer margin slightly rounded ; inner angle obliijuely rounded. Secondaries 

 reaching to the inner angle of the i)rimaries, apex acutely rounded, outer margin almost oblique, 

 hind angle rounded. Bodj^ ( $ ) slender, extending beyond the secondaries; anal tuft obsolete. 

 Legs pilose, femora and tibia- covered with long ciliated hairs, tarsi covered only with very short 

 scales. Head depressed, i)al[(i very short and barely visible, owing to the scales covering the same 

 and the thorax. Antenna- half as long as the primaries; stalk stout, with the pectinations to about 

 the middle of equal length, when they very gradually decrease in length to about 2 mm. before the 

 apex, which portion is without pectinations. The genus is allied to Hyparpa.v.''^ (Beutenmiiller.)
