NE\V GENERIC TYPES OF BOMBYCINE MOTHS. 



By Alpheus S. Packard. 



The following descriptions of new genera are published in advance 

 of the monographic revision of the families to which they are here re- 

 ferred. All of the genera of Hemileucidae are from the neogaeic 

 realm, or the tropical region of Mexico, and the South American con- 

 tinent. 



Family Hemileucid/e. 



Rhodormiscodes, gen. nov. 



Imago. — Male. Front of the head a little broader than in Orviiscodes. An- 

 tennse shorter and wider than in that genus ; as usual pectinated to the tip, the ex- 

 tremity of which is subfiliform ; antennal joints shorter than in Onniscodes. Two 

 pairs of pectinations, the distal pair larger than in Orniiscodes, those on the inner 

 side only slightly shorter than those on the outer side. Palpi ascending and project- 

 ing beyond the front, much larger, longer and wider, with shorter closer squamation, 

 than in Orniiscodes ; third joint distinct, about one half as long as second jomt is 

 wide, while in Ormiscodes they are depressed, small, short and indistinct, and with 

 irregular scales. 



Thorax with scattered long flattened hairs, as in Ormiscodes. 



Fore wings more falcate than in Ormiscodes, costa fuller, more convex toward 

 apex ; outer edge short ; wings subfalcate, but not excavated behind the apex. 

 Hind wings regularly rounded on the apex and inner angle, much more so than in 

 Ormiscodes, and of quite different shape from that genus. 



Venation : Vein II I arises near the outer end of the discal cell, /. e., much 

 nearer the origin of the anterior discal vein, and the two discal veins make a straight 

 line, not an oblique one as in Ormiscodes cinnamofnea, and they are situated inside 

 of the middle of the wing. In the hind wing veins II i, 2, 3 arise farther apart 

 than in O. cinnamomea. 



Markings : No white discal spot, but an irregular dark one. Purple tints with 

 purple-brown markings, and roseate hind wings. The abdomen is banded with yel- 

 low and black. 



This genus is based on Ormiscodes rosea Druce. 



Geograpliical Distribution. — Vera Cruz, Mexico (Franck). 



This genus differs from Ormiscodes not only in the venation, but 

 in the larger palpi, the shorter, broader antennae, subfalcate fore wings 

 and more rounded hind wings. The thorax is eqtially shaggy and 

 wooly and the legs thick and hairy. In the shape of the fore wings 

 and absence of a discal spot it somewhat approaches Hylesia.
