SOME NOTES ON AMERICAN SPHINGID/E. 



By W. ScHAUS. 

 j^lloptcs titan Cr. and ^llopus tantahis 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 

 y£llopus fadtis Cr. to be a distinct species which will be re- dis- 

 covered ere long. 



Hadoryx plato. 



Sphinx p Into 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 6". 

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

 Ent. Zeit. 1880, p. 68, and Mr. C. Oberthiir is 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 denticnlata sp. nov. 



This species only differs from C. parcce Fabr. in having the 

 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. 



GIi(BrocaiPi.a emnedon. 



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

 Cheer, ortospana Druce, Amer. Nat. Hist. (6), iv, p. 77, r889. 

 I have examined the types oi eumedon 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 achetnenides 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 Schawl., Nung. Otiosus i, p. 16 (1870). 

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