patch near the apical third of the costa. Behind this is a whitish cloud, 

 followed by a darker shade which cuts the wing directly across from about 

 1 6 mm. from the apex to about the same distance from the internal angle. 

 This darker shade encloses, a little from the apex, a heavy black streak, 

 and some shadings of brown. The lower wings are dusky brown, pale 

 along costa, bluish gray at the anal angle, and there marked by a double 

 dentate streak. Beneath both wings are brownish gray, with a submar- 

 ginal dentate line, an oblique simple median line, and on the secondaries 

 the same lines continued, the marginal one being more distinctly curved. 

 Abdomen brownish black, the segments edged rather broadly posteriorly 

 with whitish. A rather indistinct dorsal gray line, much widest in the 

 male. The thorax is gray, mottled with brown, and from the middle run 

 towards the junction of the abdomen two black lines forming an acute 

 angle, something as in Sph. cinerea. Collar transversely marked with 

 black. The shaft of the antenna? is whitish, the pectination pale brown. 



Average exp. wings, male, 115 mm.; female, do., 150 mm. 



Described from 6 examples in my collection, from Cuba, Brazil, 

 Mexico and Arizona. 



The claim of this species to a place in our fauna rests upon the cap- 

 ture of two specimens, male and female, at Tucson, Arizona, by Mr. W. 

 S. Edwards, and one male found in N. W. Texas, and now in the collec- 

 tion of Prof. O. S. Westcott, May wood, Illinois. 



There is no doubt but that this is the Sph. Hasdrubal of Cramer = 

 Macrosila Hasdrubal of Walker, and it has been so quoted by Mr. 

 Grote in his admirable paper on Cuban Sphingidas (Proc. Entom. Soc. 

 Philad., 1865, p. 64), in which notice the full synonymy of the species is 

 given. It would seem, however, that in Clemens' description of Macro- 

 sila Hasdrubal Cr., in Morris's " Lepidoptera of N. Amer.," p. 185, the 

 allusion to the male must have reference to the dark form described by 

 Butler in " Revision of the Sphingidse," p. 610, as Pseudospkinx obscurus. 

 Poey, in his description, speaking of the male, simply says that " it is 

 smaller than the female, with the black lines more distinct." This is cor- 

 rect, but the under surface is not " ash gray," which I take to be the 

 color of ashes of wood or coal, but brown gray, with the bands of a darker 

 shade. The larva is described by Poey (Cent. Lepidopt.) and a transla- 

 tion or adaptation of his description is given by Clemens, loc. cit. A 

 singular error, however, occurs with reference to the pupa. Prof. Poey
