4 New subspecies. Honduras specimens are probably referable to this form, but I have not becn able to 
examine any from that country. An example from “Central America” (probably from Nicaragua) collected by 
F. 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.
