Tbe type of ruhricosta is probably with M. Obertliiir. I have not seen 

 it. The type of cressoni I have not seen, nor do I know of its iJresent 

 whereabouts. The type of carneicosta is in the Jardin des Plantes, 

 where I have seen it. It is the form in which the ordinary spots are 

 black and distinct. The Walker types are in the British Museum and 

 are both referable here. Roseicosta Gn., was described after a drawing 

 by Abbot, and Guenee himself suspected its identity with ruhricosta. 

 I have not seen this figure, but do not doubt that the species belongs 

 here.

The type of t/recto is in the British Museum. Pyralis Hbn., is the 

 form with a rusty maculation on a bright yellow ground. The type of 

 fioccalis is in the Museum at Cambridge, where I have compared it with 

 wovmnlpyralis. Mr. Grote's genus has priority by two or throe months, 

 but the characterization fails to call attention to the interesting leg 

 structure figured by Zeller. 



P. geometralis Grt.* 



1872. Grt., Trans. Aui. Ent. Soc, iv, 24, Pleoneclyptera. 



Habitat. — Alabama; Southern States; Florida in March. 



The type is in the American Entomological Society's collection. The 

 si)ecies is exactly like pyralis in maculation, but the bright yellow is 

 replaced by a nniform rusty brown. But even in the type a yellowish 

 suffusion is perceptible, and I am convinced that we have to do with 

 forms of one species only.
