Head broader in front than long, much broader than in Tephrosia. Palpi 

 usually short and broad, not reaching beyond the front ; or slender, pointed, 

 and reaching well beyond the front (C. psilogrammaria). Antennas well 

 pectinated, but not plumose. Fore wings with the costa slightly convex, 

 especially toward the subacute apex ; outer edge very oblique, rather long, 

 not bent. Hind wings either a little elongated toward the apex or well 

 rounded, sometimes slightly scalloped. Venation : costal vein either anastomos- 

 ing with the subcostal (C. umbrosaria) or free {G. psilogrammaria). Usually 

 six subcostal venules (five in C. psilogrammaria). Usually no subcostal cell 

 [C. umbro.saria); but it is sometimes present, as in C psilogrammaria. Male 

 hind legs only moderately long ; hind tibiae much swollen, and tarsi about one- 

 third as long as the tibiae (in C. psilogrammaria very long and slender, the tibiae 

 not swollen, and the tarsi longer than the tibiae). Coloration: invariably 

 whitish or dark gray, with three sinuous black lines, often double. 



The species of this genus are numerous and widely distributed, like those 

 of Tephrosia, occurring in deep, dark woods. They are distinguished by 

 their peculiar style of coloration, being, when unrubbed, dark slate-gray, and 

 after flving about a few days becoming whitish-gray, and also by the broad 

 front, heavily-pectinated antennae, usually short palpi, and convex costa of 

 the fore wings. Contrary to what may be regarded as convenient, I follow 

 the strict law of priority, aud adopt Hubner's name Cymatophora for this genus, 

 dropping Boarmia, which is in common use. Even were Cymatophora not 

 adopted, one of Hubner's other terms, Dryocoetis or Deileptenia, would have 

 to be used, as they are well-defined groups, nearly as much so as Treitschke's 

 Boarmia, while he had no right to transfer the name Cymatophora to a genus 

 of another family (Noctuidci-).
