doubt that it has ever occurred in Illinois and believe 
that Worthington confused P. napi oleracea, or possibly 
even spring specimens of P. rapae with this species. 
Phoebis agarithe (Boisduval) 
Large orange sulphur 
Phoebis agarithe: Klots 1951:191. 
This butterfly was listed by Klots as straying north 
‘0 Illinois. 
Kricogonia lyside (Godart) 
Lyside 
Kricogonia lyside: Klots 1951:194. 
The statement for the preceding species applies to 
his one as well. 
RIODINIDAE 
Calephelis borealis (Grote & Robinson) 
Northern metalmark 
tharis borealis: Worthington 1880:48. 
phelisca borealis: Klots 1951:123. 
We believe that Worthington’s record of Charis bore- 
lis referred to C. muticum, then unrecognized as a sep- 
rate species, but true C. borealis may also occur in 
llinois. We have taken it in some numbers as far west 
s Howard County, Indiana, and it has been reported 
lso from Montgomery County, Indiana, even closer to 
llinois. McAlpine (1971) recorded it from Missouri. 
LYCAENIDAE 
Phaeostrymon alcestis (Edwards) 
Alcestis hairstreak 
irymon alcestis: Klots 1951:135. 
A report of this species from Carbondale, Jackson 
ounty, obtained during this project could not be veri- 
ed. Its occurrence as a casual as far east as Illinois, 
Owever, seems possible. 
Satyrium boreale (Lafontaine) 
This species was recently described (Lafontaine 
69, 1970 [Two dates because name was validated in 
Tor and was redescribed.]). It was not practical to 
“examine all Illinois falacer to check the possible 
‘esence of the new species among them, but in view of 
} reported occurrence in Michigan, Ohio, and Penn- 
lvania, it may be found in Illinois as well. The most 
/'spicuous superficial distinction between boreale and 
lacer is the reduction of the subterminal line on the 
iderside of both wings in boreale. On the primaries, 
1S usually consists only of two spots between veins M, 
id Cu,; on the secondaries, it is reduced or absent 
"af 
above vein M,. There are apparently good genitalic 
distinctions also (Lafontaine 1970: 84-85). 
Callophrys augustinus (Westwood) 
Brown elfin 
Incisalia augustinus: Klots 1951:146. 
The range of this species as given by Klots was 
“Newfoundland w. to Manitoba, s. to Virginia, West 
Virginia, Illinois, and Michigan.” It probably occurs 
locally in the state. It was listed by French (1879), but 
Worthington (1880) doubted its presence in Illinois. 
Lycaena epixanthe (Boisduval & Le Conte) 
Bog copper 
Lycaena epixanthe: Klots 1951:152. 
Klots included northern Indiana and “(?) Iowa” in 
the range of epixanthe. Blatchley (1891) recorded it as 
“rare” in Lake County, Indiana. However, Masters & 
Masters (1969) rejected this record, suggesting that 
Blatchley’s records may have been of L. helloides, which 
he did not list. According to Klots, epixanthe is strongly 
restricted to “acid bogs where the food plant, Cranberry, 
grows.” Jones & Fuller (1955) recorded cranberry (Oxy- 
coccus) from bogs in McHenry, Lake, Cook, and Will 
counties. The well-known Volo bog in Lake County is an 
acid tamarack bog, and the occurrence of epixanthe 
there seems theoretically possible. L. epixanthe was listed: 
by French (1879), but Worthington (1880) -doubted its 
occurrence in Illinois. 
Plebeius saepiolus (Boisduval) 
Saepiolus blue 
Plebeius saepiolus: Klots 1951:167. 
Klots gave the range of saepiolus as “all of southern 
Canada, s. into Iowa, Minnesota, Michigan, and Maine” 
and stated that the species is extending its range. He 
suggested that it may continue to do so southward, in 
which case it might in time reach as far south as northern 
Illinois. 
NYMPHALIDAE 
Limenitis archippus floridensis Strecker 
Limenitis archippus floridensis: Klots 1951:115. 
This butterfly was listed by Blatchley (1891) from 
“Illinois,” without autho~ity or further information, 
Possibly an unusually dark individual variant of this 
clinal species was so determined. 
Phyciodes phaon (Edwards) 
Phaon crescent 
Phyciodes phaon: Klots 1951:99. 
P. phaon was recorded by P. S. Remington (1956) 
as having been taken in St. Louis County, Missouri, and 
he told us (personal communication) that he saw no 
reason why it should not occur in Illinois. Klots gave its
