Polites vibex (Geyer) 
Whirlabout 
Polites vibex: Klots 1951:247. 
This skipper may occur northward at least as far as 
southern Illinois. Klots gave Connecticut and Arkansas 
as the northern limits of its range. It is generally distrib- 
uted and quite common in Mississippi (Mather & 
Mather 1958). 
Hesperia metea Scudder 
Cobweb skipper 
Hesperia metea: Klots 1OD le 2a: 
Illinois lies well within the range of this skipper but 
we have no records from the state. We see no reason why 
it should not occur in Illinois. 
Hesperia attalus (Edwards) 
Dotted skipper 
Hesperia attalus: Klots 195 leo: 
The range as given by Klots was “Florida and Texas, 
n. to Massachusetts, Ohio, Wisconsin, and Nebraska.” 
It may be expected to occur in Illinois; if it does, it has 
probably been overlooked or confused with other Hes- 
pera. 
Oarisma garita (Reakirt) 
Garita skipper 
Thymelicus garita: Worthington 1880: 48. 
Oarisma garita: Klots 1951:231. 
As previously explained in connection with Oarisma 
powesheik, we believe that the listing of garita by French 
(1879) and Worthington (loc. cit.) must have been 
based on confusion with the former species. 
Erynnis lucilius (Scudder & Burgess ) 
Columbine dusky wing 
Erynnis lucilius: Klots 1951:227. 
E. lucilius almost certainly occurs at least in northern 
Illinois, despite the lack of positive records. It is insepar- 
able from E. baptisiae, by morphological characters, so 
that host plant association is essential for its recognition. 
None of the material labeled Jucilius which we examined 
*n the Field Museum and Illinois Natural History Sur- 
vey collections was so associated. In view of this defi- 
ciency, we do not feel justified in accepting the records. 
Although Burns (1964) stated that he had examined an 
undoubted lucilius from the “vicinity of Chicago, Illi- 
nois,” data for this specimen were unavailable. The term 
“vicinity of Chicago” has sometimes been used to include 
closely adjacent northwestern Indiana. 
Burns (1964) indicated that E. lucilius and E. bap- 
tisiae are predominantly allopatric, with the former hav- 
ing a northern and the latter a southern distribution with 
only a narrow belt of territory where they exist in sym- 
patry. For this reason, it is to be expected that E. lucilius 
will be confined to northern Illinois, since baptisiae is 
believed to occur throughout the state. E. lucilius feeds 
upon Aquilegia (columbine), and any Erynnis found 
ovipositing upon or reared from this plant should be 
very carefully host associated and the fact reported. 
Erynnis persius (Scudder) 
Persius dusky wing 
Erynnis persius: Klots 1951:226. 
This species may occur at least rarely in the state, 
a belief shared by Burns (personal communication). E. 
persius itself is separable from the other two members 
of its species group (E. lucilius and E. baptisiae) by fair- 
ly recognizable morphological characters of the adult, 
and in addition is oligophagous in comparison with the 
highly restrictive host specificity of the other two species. 
The records of “persius” by French (1879) and Wor- 
thington (1880) are almost certainly based upon con- 
fusion with the other members of the group, probably 
E. baptisiae. Burns (1964) stated that E. persius is strict- 
ly univoltine (May-July) in the eastern portions of its 
range. 
Thorybes confusis Bell 
Confused cloudy wing 
Thorybes confusis: Klots 1951. 2033 
Klots gave the range of confusis as “Florida to Texas 
n. to Kansas, Missouri, and Maryland.” It may occu 
in southern Illinois. The record by Cushing (1970) of 
confusis from Madison County was based on misidenti: 
fied material. 
Urbanus proteus (Linnaeus) 
Long tailed skipper 
Urbanus proteus: Klots 1951:207. 
Klots indicated that the northward distribution c 
this species in the Mississippi Valley is uncertain; sinc 
it has been recorded from several northward localities 4 
a casual, it may occur in southern Illinois. 
PAPILIONIDAE 
Papilio palamedes Drury 
Palamedes swallowtail 
Papilio palamedes: Klots 1951:178. 
This species may rarely stray northward as far | 
extreme southern Illinois. Klots said, “In Mississip 
Valley uncommon, n. to Missouri (rare) .” Mather 
Mather (1958) considered it “rare” in northern Miss 
sippl.
