280 BIRDS OP ILLINOIS. 



Only one species of this southern genus is known to occur in 

 Illinois. Another however, may be expected, at least as a straggler, 

 and for this reason the comparative characters of the two are given 

 here. 



1. P. aestivalis. Adult: Above reddish brown, streaked with gray, and usually spotted 

 on the back with black; beneath dull buffy. whitish on the belly. Middle tail-feathers 

 without distinct bars. 



Of. cestivalis. Crown streaked with blackish, and black streaks on back always 



very distinct. Hab. Florida and lower Georgia. 

 /3. bachmanii. Crown without black streaks, and black streaks on back frequently 



obsolete: general coloration much more "sandy" above, and clearer, or less 



dingy, buff below. Halt. North and South Carolina, west to eastern Texas, north 



to southern Illinois and Indiana. 



2. P. oassiui. Above brownish gray, spotted with grayish brown and black, but with no 

 rusty; lower parts nearly uniform brownish white or pale brownish gray. Middle 

 tail-feathers very distinctly barred with dusky. Bab. Southwestern U. S., north to 

 Kansas.

*In a letter dated April 27. 1884, Professor David 8. Jordan. President of the Indiana 

 State University, writes me as follows: "It may perhaps interest you to know that two 

 specimens of Peuccea cestivalis illinoensis have been taken at Bloomington (April 24). 

 They were shot in a brush heap."
