Sept. 1896] ScHAUS : New Species of Heterocera. 135 



genus Erithales will no doubt sink as a synonym of Encereon, or 

 the latter must be divided into several genera. Of the twenty-nine 

 species I possess I make five groups according to slight differences in 

 neuration. 



Amaxia juvenis, sp. nov. 



$ . Head yeJlow above, crimson underneath. Collar yellow. Thorax viola- 

 ceous brown. Abdomen crimson above, yellow ventrally. Primaries bright yellow ; 

 a large violaceous brown space from the costal vein at a third from the base to the 

 inner angle, except the costal margin itself, which remains yellow, and a small yellow 

 spot at the middle of the inner margin, this latter spot being edged with crimson; and 

 there are also some crimson scales at the base of the inner margin ; some dark gray- 

 ish spots in the cell ; beyond the cell three transverse rows of spots, the first and 

 outer rows small, the center row also small except towards the outer margin where 

 they become large and confluent and are more or less shaded with crimson ; the ex- 

 tremeties of the veins crimson. Secondaries pink ; broadly yellowish along the cos- 

 tal margin. 



9 . Differs in having the dark basal space broken up into large spots more or 

 less broken up into large spots more or less confluent, and the rows of transverse spots 

 especially the central row, consists of a series of large spots edged with crimson. The

 these a large similarly colored and irregular space extending from the subcostal vein 

 to the inner margin, where it reaches the inner angle ; two terminal rows of small dark 

 spots ; the median yellow space with some small spots and at a fourth from the apex 

 four large and confluent brownish gray spots extending from vein 5 to the costal
