Province, P. J. Darlington. Many miscellaneous specimens inter- 

 cepted at the border on bananas from Mexico, Guatemala, Honduras, 

 Costa Kica, and Panamd. 



Remarks: This species has long been classified under the genus 

 Cacoscelis. There is, liowever, no generic character that I can find to 

 separate it from the vittate Disonj^chas. There is no emargination 

 of the middle or hind tibiae such as occurs in some species classified 

 imder the genus Cacoscelis. Latreille in his original description wrote 

 that quinguelineata had a great affinity with Disonycha caroliniana 

 (Fabricius). I believe that it is simpl}^ an unusually large species of 

 Disonycha but not much larger than D. militaris or species of the 

 aliernata group. At least one specimen has been confused by Jacoby 

 with D. militaris Jacoby (see note under D. militaris). This and the 

 following species, as well as D. stenosticha Schaeffer from Browaisville, 

 Texas, belong to a group of closely related species.
