beyond the front and pointed, sometimes {Dasufidonia) very hairy and large, 

 while the antennae arc almost invariably well pectinated, often plumose (excepl 

 in Semiothisa, where they arc simple). The fore wings arc broad, sometimes 

 narrow and subfalcate, or, when broad, with the apex more or less rectangu- 

 lar, and the costa unusually straight. The hind wings are large and rounded, 

 seldom angled. The venation is quite characteristic, the costal being often 

 united with the subcostal, and the latter usually throwing off three short 

 branches to the costa. Either one or no subcostal cell The species arc 

 often high-colored, red or dark brown or deep ochreous, with dark or lighter 

 lines and spots. Abdomen very long and slender, much more so than usual. 



Larva. — " Caterpillars elongated, cylindrical, ordinarily without swellings 

 or eminences; head globular, as wide as the prothoracic ring, with the anal 

 part terminated by two horizontal points; generally living on low plants. 

 ( Jhrysalides usually subterranean." — GuemV. 



In GueneVs "Zerenidee", tin; caterpillars are described as short, rather 

 thick. 



I do not see good grounds for separating the u Macaridce v from the
