* New subspecies. Honduras specimens are probably referable to this form, but I have not been able to 

 examine any from that country. An example from " Central America" (probably from Nicaragua) collected by 

 P. Hicks (Nat. Mus. No. 40973) agrees closely with the darker-colored examples from Guatemala, but the 

 spotting on breast is still heavier and apparently extends backward over whole abdomen.
