from the central and south-central portions of the peninsula. The 

 information from the Tropical area of southern Florida is relatively 

 full. 



The zonal distribution of the species treated in the present paper 

 is tabulated below. In some cases it is known that the species, in 

 certain regions of North America, occur in zones other than those 

 here checked, but, unless this has a distinct bearing on the possible 

 occurrence of the species in the same zone in the region here studied, 

 we have not indicated its presence other than as found in the south- 

 eastern States. In a few cases where species will in all probability 

 be found in a certain zone in the southeastern States, judging by 

 the analogy of other regions, or where the form is found in two 

 zones, but by defect of the record is not known from one situated 

 between these two, we have inserted a check for that life zone with 

 a brief qualification.
