no. i. BOMBYCINE MOTHS OF NORTH AMERICA— PACKARD. 73 



Markings: Body and wings of a beautiful delicate uniform pink or brown, with several 

 transparent eye-like spots in the middle of the wings and some outside of the discal cell. 



This remarkable moth is at once distinguished by its extraordinarily long tails. That 

 they at least do not aid flight is indicated by the statement in Drury: "Its flight is exceedingly 

 slow, and its tails seem rather to impede it." (Illustrations.) The remarkable length of the 

 palpi is noteworthy, as well as the presence of maxillae. 



The genus appears to be an offshoot from some Urota like genus, and in its venation is 

 allied to Urota. It evidently forms a group by itself of subfamily rank. 



Geographical distribution. — Thus far it is only known from the west coast of Africa, Sierra 

 Leone. 



Larva. — Head a little above the median size, roundish. Body cylindrical, rather thick, 

 and heavily armed with stout spinulated tubercles; those of the thoracic segments in eight 

 rows, four rows on each side, while there are six rows, as usual, on the abdominal segments. 

 The tubercles of the two dorsal rows on the prothoracic collar are short and moderately high. 

 Those of the second and third thoracic segments and the median tubercle on the eighth abdominal 

 segment are a little larger than the other abdominal ones, the tubercles are large, the base 

 fleshy, above solid chitinous and bearing very stout spines of unequal size, two being terminal 

 and forming a fork. 



The median spine on the eighth abdominal segment larger than the other abdominal ones, 

 bilaterally symmetrical, ending in four spike-like spines, two on each side, those of one pair 

 diverging from those of the other. 



Suranal plate large, thick, rounded, and armed with an unusually large spinulated spine 

 on each side a little beyond the middle of the plate; in shape like those of the supraspiracular 

 row on the eighth abdominal segment. Anal legs large, subtriangular, sphingiform; granulated 

 and setose. 



Stage before the last. — The dorsal tubercles of equal size and height both on the thorax and 

 abdomen; the terminal spine of each tubercle longer than in the last stage, erect. The two 

 inner tubercles of the prothoracic collar simpler and slenderer than the others, ending in a single 

 spine. Suranal plate as in the last stage. 



Pupa. — Of unique shape and type of armature; body flattened, head and end of abdomen 



inclined downward; eyes rough, hedged in with irregular setae; wing covers with transverse 



rows of scraggy setae; no visible indications of mouth-parts and legs; abdomen ending in 



three points, the middle one the cremaster, a flattened tooth; a mucronate tooth on each side, 



all armed with stiff appressed setae pointing backward; beneath at base two deep pits; no 



terminal hooks. A highly specialized pupa, extremely modified, apparently from the Sphingi- 



campid type.

Imago. — Two <? , two $ . Head, body, and wings of a soft delicate flesh or salmon reddish 

 pink. Antenna? black-brown. Fore wings adorned with a group of from one to five or six 

 little round ocelli, which are transparent in the center, where there is but a single one, it is the 

 discal spot on the outside of the upper discal vein, which is broadly lunate, faded ochre and 

 ringed with brown, only half the width of the discal area, or it may be double like the figure 8,
