 Texas, in March, April, and August. 



The type of rubricosta is probably with M. Oberthiir. I have not seen 

 it. The type of cressoni I have not seen, iior do I know of its present 

 whereabouts. The type of carneicosta is in the Jardiii 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 Gueuee himself suspected its identity with rubricosta. 

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



here.

HABITAT. Middle, Southern and Central States; Texas. 



The type of irrecta is in the British Museum. Pyralis Hbn., is the 

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

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

 normal pyralis. Mr. Grote's genus has priority by two or three months, 

 but the characterization fails to call attention to the interesting leg 

 structure figured by Zeller. 



P. geometralis Grt.* 



1872. Grt., Trans. Am. Ent. Soc., iv, 24, Pleonectyptera. 



HABITAT. Alabama; Southern States; Florida in March. 



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

 species is exactly like pyralis in maculation, but the bright yellow is 

 replaced by a uniform 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.
