"The most comprehensive collection of Illinois butter- 
ies is at the Illinois Natural History Survey. Individual 
ailections deposited in the Survey collection are those 
[ R. M. Barnes (in part), E. Beer, A. Bolter, R. R. 
rwin, A. Mares, A. H. Mundt (via the Irwin and R. M.

ie Chicago area collection of J. W. E. Glattfeld and 
me local material. 
Southern Illinois University at Carbondale possesses 
1 excellent collection of southern Illinois butterflies. 
here is no longer any G. H. French material at this

‘tant French butterflies are in other collections. 
The above institutional collections cited, and others 
om which fewer records were obtained, are abbreviated

We acknowledge, with sincere gratitude, the as- 
tance of the following persons for determination of 
ecimens, information, many helpful suggestions, read-

Dr. C. L. Remington kindly allowed us to use freely 
a manuscript, “Annotated check list of the Rhopalocera 
of Elsah, Illinois,’ which he prepared as a result of 
his observations on the campus of Principia College. 
He had also published (Remington 1943) on these ear- 
lier. 
Mr. Louis D. McNeese of Centreville, St. Clair Coun- 
ty, collected for us during the summer of 1966, and ob- 
tained many new county records. 
Mrs. Jane Merchant of Southern Illinois University 
assisted us in locating a copy of French’s 1879 list of 
Illinois butterflies. 
In processing the manuscript for printing, at the 
Illinois Natural History Survey, O. F. Glissendorf and 
P. W. Smith did the final manuscript review and edit- 
ing, and Lloyd LeMere designed the cover. 
Grateful acknowledgment is made to the Illinois State 
Academy of Sciences for the support of this project

BUTTERFLIES OF ILLINOIS 
HESPERITDAE 
Panoquina ocola (Edwards) 
Ocola skipper 
Hesperia ocola Edwards 1863a:20 (type-locality “Geor- 
gia, Florida and Texas’’). 
Prenes ocola: Holland 1931:398. 
Panoquina ocola: Klots 1951:270; dos Passos 1964:3 
(No. 24). 
Illinois records.—Jersry County: Pere Marquette 
State Park, September 10, 1935, Lauck (CW). 
We have not seen this specimen, but we believe the 
record to be valid. The species probably occurs at least 
occasionally in the southern counties. 
Calpodes ethlius (Stoll) 
Brazilian skipper 
Papilio ethlius Stoll 1782(4) :212 (type-locality “Suri- 
nam’’). 
Calpodes ethlius: Holland 1931:399; Klots 1951:269; 
dos Passos 1964:3 (No. 27). 
Illinois records—Coox County: Chicago, emerged 
August 27 and August 29, 1923, from larvae found on 
Canna, Dohmen (FMNH). 
This skipper is probably not established anywhere in 
Illinois, occurring only when introduced on Canna, or 
perhaps occurring casually in extreme southern Illinois.
