NORTH AMERICAN LEPIDOPTERA. 199 



by Mr. Grote. I believe also that Clemens' locality was erroneous, 

 or that the species is but a visitor, as is S. tetrio and some others. 



The result of this is that the genus Diludla loses two of the species 

 referred to it, and disappears from our faunal lists, leaving jasmine- 

 arum, as the representative of a distinct generic type.

Head and thorax pale ashy gray, with a transverse line on prothorax extended 

 through the middle of tegulse and over the metathoracic tufts, completing the 

 ring, sometimes the dorsum of thorax has an indefinite line each side of the 

 middle. Abdomen dull gray, with a darker, narrow dorsal line and a broad 

 lateral band containing large round pale spots, often interrupting the band. Pri- 

 maries pale ashen gray with blackish brown markings. A blackish streak from 

 base, along inner margin; two very irregular, dentate, transverse lines about 

 one-third from base, not very distinct. Beyond the middle a series of three much 

 more distinct scalloped lines straight from costa to middle, then inwardly curved. 

 Beyond this' is another lunulated and more or less interrupted line, not so dis- 

 tinct as those before described. From the basal bands on costa a blackish shade 

 band extends obliquely across the wing to the middle of the outer margin, and 

 below this from the basal transverse lines extends a short spur of the same color. 

 An irregular, subapical black streak. Discal spot white, small ; beyond it an ir- 

 regular yellowish brown blotch. Fringes white, cut with black. Secondaries 

 black, with a faint grayish central band, and the outer margin grayish powdered, 

 wider toward anal angle. Beneath, nearly uniform dull fuscous with two com- 

 mon, darker, central bands. Expands 4—4.25 inches; 100-105 mm. 



Hub. — New York, New Jersey, Pennsylvania, Maine, Canada, 

 Maryland, Georgia. 



The genitalia are, in the supra-anal plate, after the general type. 

 The side piece is broad, the clasper large, broad, ladle shaped, ab- 

 ruptly bent beyond its base, the terminal margin serrate and dentate. 



The species is rare, and apparently not very widely distributed. 

 My list gives Canada and Maine as localities without authority. 

 Prof Fernald omitted the species because not certainly recorded 

 from New England. 



There is no difficulty in recognizing the species. Superficially it 

 resembles Ceratomia, but is readily distinguished by the oblique 

 black shade band heretofore mentioned.
