SYNTOMOIDEA H-S. 
Genus OMOIALA m. 
Omoiala vermiculata m. Plate 6. Fig. 1. 
Habitat. Pike’s Peak. Coll. Ent. Soc. Philad. 
Gen. CTENUCHA Kirby. 
On page 174, Vol. 2, Proc. Ent. Soc. Phil., I described, under the 
present family, a new and beautiful species belonging to the genus 
Ctenucha Kirby, C. Gressonana m. (Plate 8, fig. 5), and in presenting 
the diflerences between it and other described species belonging to this 
genus, I referred to C. Latreillana Kirby, which latter species, though 
generally known under the name which Kirby gave it, has been recog- 
nisably figured and named by Charpentier in his edition of Esper’s 
Exotic Butterflies. 
This species will be found figured on one of two supplementary 
Plates, not given by Esper in the original work, and I find no allusion 
to them in the accompanying text. (Vide Hagen Bib. Ent. Vol. 1, 
p. 216.) I therefore offer the following as the correct synonymy of 
this species, and one which has apparently been heretofore overlooked. 
Ctenucha virginica Charpentier. 
Sphinx 1 virginica Charp. Edit. Esp. Exot. Schm. Sphing. Exot. Plate 2, fig. 
Z%, 49 , 1830. 
Ctenucha Latreillana Kirby, Fauna Bor. Am. IV, p. 305, 1. (428) 1837. 
G-laucopis Latreillana Harris, Descr. Cat. N. Am. Sphing 39.5. 
Ctenucha Latreilliana Gosse, Can. Nat. p. 249. 
Ctenucha Latreillana Walker, C. B. M. Het. p. 282. 
Ornamenta alarum hujus specie! Stalachtis heliconides Bd. memorabile 
similia sunt. 
Spero, nomen, quod pro illo elegi, non diagnosis certe positum genus, nulla 
tarn non necessita et incerta dicta accepturum esse, ut nomen Eumetopona in 
Vol. 1, p. 296, hujus scripturse accepit. 
(I substitute Omoiala for Lamprosoma, having discovered, unfortunately too 
late to make the correction on the Plate, that the latter name was preoccupied 
by Kirby in Coleoptera.)
