UNIDENTIFIED SPECIES. 
I am unabie to recognize the following species, which have 
been described as having been taken within the geographical 
limits covered in this paper, though I have in some cases ven- 
tured to guess at what they may be. The name given is that 
under which the description was published. 
SCOLIA ANCEPS Saussure. 
Scolia anceps Sauss., Ann. Soc. Ent. France, (8), VI, 1858, p. 221, n. 32, o. 
I think from Sassure’s description that this species is the one 
that Burmeister has described as haematodes. 
SCOLIA BIDENS. 
Sphex bidens L., Syst. Nat., Ed. XII, I, 1767, p. 943. 9 o Eur. mer.; Afr. bor.; 
(Am. bor.). 
This is a well known Old World species and as there is no 
recent record of its capture in America it is probably an erron- 
eous record and may safely be omitted from the American 
faunal lst. Saussure and Sichel in their Cat, Spec. Gen. 
Scolia say it is recorded from North America (by error?). 
SCOLIA BIFASCIATA Swederus. 
Sphex (Scolia) bifasciata SWEDERUS, Svensk. Vet. Akad. Handl. VII, 1787, 
. 281, n. 35. New York. 
Scolia bifascata GMELIN, Linne, Syst. Nat., Ed. 13, I, 5. 179a, p. 2738, n.26. 
I have not seen the original description by Swederus but 
only that of Gmelin which I assume is a copy. From this I am 
unable to determine anything in regard to this species. 
ScCOLIA MEXICANA Saussure. 
Scolia mexicana Sauss., Ann. Soc. Ent. France, (8), VI, 1858, p. 213, n. 23, 9. 
Mex. 
From Saussure’s description I am unable to recognize this 
insect, but it is probably only a variation of Scolia guttata 
guttata. 
SCOLIA NOBILITATA variety MACULATA Guerin. 
Scolia maculata GUERIN, Duperry, Voy. Coquille, Zool. II, p. 2, 1830, p. 255 9. 
paw Age ag var maculata Sauss. and Sichel, Cat. Spec. Gen. Scolia, 1864, 
I have not seen Guerin’s description but Saussure and Sichel 
in their catalogue give what I suppose is a copy of it. From 
this the writer has been unable to draw any conclusions in 
regard to maculata.
