no. i. BOMBYCINE MOTHS OF NORTH AMERICA— PACKARD. 81 



Fore wings short and broad, costa nearly straight, more incurved in 9 , whitish gray on a 

 tawny ground. Basal line black, distinct, arising from a largo black oblong costal spot on the 

 inner third of the wing, and ending near the middle of the inner edge; the line makes a small 

 angle on vein III. Discal spot distinct, white, narrow, either straight or slightly curved and 

 situated midway between the basal and extrabasal line; the latter a zigzag white narrow line 

 edged externally with dark brown, ending on the costa in a black conspicuous mark. Beyond 

 this line the wing is clear tawny, but darker on the outer edge of the wing beyond the irregular 

 zigzag edge of the tawny region, the outer edge being coppery red-brown in 9 . Veins black 

 in o* , not so dark in the 9 , except toward the edge of the wing. 



Hind wings of <? of the same hue, being pale tawny as in Molippa sabina, no discal spot, 

 and with two outer scalloped lines, the outer of the two lines more diffuse. Ends of the veins 

 on the outer edge black. In $ the wings are darker and reddish brown, especially on the 

 outer third. 



Beneath only faint traces of the discal spots, and no lines. Margin of the wing of <? 

 spotted with black, uniformly pale tawny; in the 9 there are more decided traces, especially 

 on the veins of the extradiscal line, but the general hue is a pale faded purplish reddish brown. 



Thorax tawny and black, mixed with longer pale clavate hairs of different lengths. Abdo- 

 men extending well beyond the hind wings, of a Scotch snuff yellow color, with broad black 

 rings ; the extremity yellow ocher. 



Expanse of fore wings, d 55 mm.; 9 66 mm. 

 Length of fore wings, o* 30 mm. ; 9 34 mm. 

 Breadth of fore wings, <? 15 mm.; 9 18 mm. 



The discal spot larger than in any other species of the group known to me. 



CATOCEPHALA ALANUS Blanchard. 



Plate LIII, fig. 3 (Dirphia alarms). 



Catocephala alanus Blanchard in Gay, Hist. [I fail to trace any publication of this species. It is not in Kirby'a 

 Catalogue. Mr. Samuel Henshaw has kindly looked in Gay's Fauna Chilena, and reports that C. socialis and 

 C. rufosignata are the only species of the genus mentioned in that work; both on p. 63 of Vol. VII.] 



Imago. — One <? , one 9 • Uniformly reddish or brick-red brown. The back part of the thorax 

 and the abdomen on the sides and beneath dull reddish ocherous. Long black paddle-shaped 

 hairs arise from front of the thorax. 



Fore wings very slightly subfalcate, outer edge very slightly excavated, while that of 

 C. rufosignata is not so. Wings with a frosting, tinged with lilac on the outer margin and at 

 base. A dark brown basal line situated nearer the discal spot than the base of the wing. Discal 

 spot small, oval, narrow, white. Extradiscal line narrower than the basal line, not scalloped, 

 slightly curved outward opposite the discal area. 



The hind wings with no discal spots, slightly paler and clearer than the fore wings. Extra- 

 discal line rather broad and diffuse and bent outward opposite the discal area; a second sub- 

 marginal line. Wings beneath a little paler and clearer than above and the extradiscal lines 

 are faintly reproduced. On the hind wings is a broad reddish clear shade on the outer fourth 

 of the wing, corresponding to the space between the two lines on the upper side. Abdomen 

 dull ocherous at base above, beyond black brown, not ringed or banded, and on the sides and 

 end and beneath dull ocherous. 



Expanse of fore wings, o* 72 mm. ; $ 87 mm. 



Length of fore wings, J 37 mm. ; 9 45 mm. 



Breadth of fore wings, <? 21 mm.; 9 22 mm. 



Length of hind wing, <? 30 mm. ; 9 32 mm. 



Breadth of hind wing, <? 20 nun. ; 9 20 mm. 

 This species very different in color and markings from C. rufosignata, the lines not being 

 scalloped and the wings more uniformly clear and plain, and it is a larger species, but struc- 

 turally the two species are congeneic.
