SOME NOTES ON AMERICAN SPHINGID/E. 



By W. SCHAUS. 



sEllopns titan Cr. and sEllopus tantalus Linn, can always be 

 differentiated by the presence in the former species of the gray 

 scales at the anal angle of the secondaries above. I have 

 examined several hundred specimens of both species and have 

 never found the slightest difficulty in separating them. I believe 

 A^llopus fadus Cr. to be a distinct species which will be re dis- 

 covered ere long. 



Madoryx pluto. 



Sphinx pluto Cr., Pap. Exot. iii, t. 216, E (1779). 



Hemeroplanes plutonius Hiibn., Verz. bek. Schmett. p. 133. 



Madoryx deborrei Bd., Sp. Gen. Het. i, p. 155 (1875). 

 Boisduval's M. deborrei is evidently the 9 of Cramer's 5". 

 pluto; the identity was first suggested by Maassen in the Stettin 

 Ent. Zeit. 1880, p. 68, and Mr. C. Oberthuris of the same opinion. 

 I have recently received both sexes from Jalapa, Mexico, the spe- 

 cies not having been previously recorded from Central America. 



Calliomma denticulata sp. nov. 



This species only differs from C. parctz Fabr. in having tin- 

 outer margins of the primaries very denticulate, and I should 

 hesitate to consider it a distinct species, had I not seen a second 

 specimen in the Saunder's coll. at Oxford. Expands 63 mm. 



Hab. Jalapa, Mexico. 



Choerocampa eumedoa. 



Cheer, eumedon Bd., Sp. Gen. Het. i, p. 272, 1875. 

 Cheer, ortospo.na Druce, Amer. Nat. Hist. (6), iv, p. 77, rSSg. 

 I have examined the types of eicmedon and ortospana, and find 

 them identical. 



Pachylia resumens Walk, and Pachylia inconspicua Walk, are 

 the same, the latter being a rather large female. 



Oryba achemenides. 



Sphinx achemenides Cr., Pap. Exot. iii, t. 225, C. (1779). 



Oryba robusta Walk., (nee. Bd.) Cat. Lep. Het. B. M. viii, p. 197 



(1856). 



As already stated by Mr. Druce in Amer. Nat. Hist. 1890, p. 

 214, Cramer's and Walker's species are conspecific. 



Oryba kadenii. 



Pachylia kadenii Schauf., Nung. Otiosus i, p. 16 (1870). 

 Pachylici robusta Bd., Sp. Gen. Het. i, p. 135 (1875).
