This species seems to diifer from I. inversa iu having no pale band 

 across the secondaries. They may yet prove to be identical. 



APATELODES nov. gen. 



Front of the head rather broad subtriangular. Antennae in % evenly 

 branched to the tip, as long as the thorax. Palpi slightly ascending, 

 reaching to the front, tips broad ; third joint minute, concealed. Pri- 

 maries triangular, broad; costa straight, outer margin incised just below 

 the apex, which is acutely produced, especially in the 9 . Below the 

 apex the outer edge of the wing is oblique, not indented, but making 

 an obtuse angle with the straight inner edge. Costal nervure extend- 

 ing nearer the apex than usual. Second and third subcostal nervules 

 suddenly deflexed upon the costa. Apical interspace broadly triangular. 

 The 4th subcostal arises iu the middle of the wing. Discal area short 

 and broad. . 



Secondaries large, full and rounded on the outer margin, of an irre- 

 gular pentagonal form, reaching nearly to the tip of the abdomen. 

 Femora densely pilose, giving the joint an oval form ; hind tibiae with 

 four large spurs. Abdomen of S slender, and provided with two late- 

 ral tufts on each side of the tip. 



This genus approaches the Dasychirae in possessing very heavily pec- 

 tinated antennfe, large clavate palpi, a stout woolly thorax, and a slen- 

 der, tapering abdomen; also in having large hind wings, and heavily 

 tufted legs, and, in some respects, in the pecviliar brown colors. 



The larva is also haii-y, with long pencils of parti colored hairs, which 

 is characteristic of the preceding group. This genus in its larval 

 stage, judging from Abbot's drawing, bears a striking resemblance to 

 the larva of Apatela americ<ina, which has susgested the generic name. 

 Our species cannot be referred to Parathyris Htibner, of which P. 

 cedo-nalli (Cramer sp.) is a type, and the term Pyijstra has been re- 

 stricted to an European group.
