large, about as broad as long. Figured from reared specimen from 

 Audubon Park, La. 



Abdomen of male with a pair of hair tufts on second segment. 



Well distributed throughout tropical America from the Gulf coast 

 of United States to Mexico and Argentina, including the Antilles. 

 We are unable to distinguish any racial forms. The above synonymy- 

 is taken from Hampson in respect to the Walker, Zeller, and Felder 

 species. This is a well-known enemy of the sugar cane in tlie larval 

 stage. 



The HoUoway and Loftin bulletin, cited above, gives a complete 

 account of the insect, with figures and detailed descriptions. In 

 that paper there is an error in the larval description and the figures 

 (pi. 4) of the head capsule of sacckaralis and zeacoleUo} for which 

 the present junior author (Heinrich) is responsible, and which we 

 would correct here. The frontal punctures on the epicranium are 

 described as "well separated; distance between punctures consid- 

 erably greater than distance from puncture (F^) to frontal seta 

 (F^)"; and the figures of the head capsules of both saccliaralis and 

 zeacolella show them so. In reality the punctures lie very close 

 together and immediately between the frontal setae in all species of 

 Diatixieai. 



Chilo cranibidoides Grote, which we retain here as a synonym, will 

 doubtless prove to be actually an earlier name for Dlatraea zeacolella 

 Dyar. However, we have not examined the type.
