 ic&3 J CLARK — THIRTY-THREE NEW SPHINGIDAE 49 



second received recently from Mr. A. Bang-Haas, with no more specific 

 locality than Bolivia. 



Dr. Karl Jordan, commenting on the first specimen, March 

 31, 1919, said "In structure the same as scutata, probably a 

 subspecies or geographical form." Before describing it, I 

 waited for another specimen. It seems certain that this form 

 from Bolivia lies between the northern P. scutata R. and J. and 

 P. scutata brasiliensis R. and J. from Rio de Janeiro. It is 

 smaller than either of them, and much lighter in color through- 

 out. 



First segment of palpus lighter in tone than in the other subspecies, as 

 is the thorax. 



Fore wing above: Ground tone light gray; postmedian band, formed 

 by the dark slaty sericeous patches, much narrower than in the other forms 

 of this species. Wing less washed with brown and with white, giving a 

 more uniform appearance. 



Fore wing beneath: Lighter in color, with three strongly marked post- 

 median bands and a broad marginal band. 



Hind wing above : White submarginal band closer to wing margin than 

 in P. scutata, as close as in P. scutata brasiliensis. This band is less ob- 

 scured by gray than in P. scutata brasiliensis. 



Hind wing beneath: Postmedian band narrower and heavier than in 

 either of the other forms. 



Sphinx tricolor sp. nov. 



Al. ant. long., c? , 44 mm. Al. ant. lat., cf , 17 mm. Marg. ext., cf, 

 23 mm. 



Habitat. — Dominican Republic. 700 metres altitude. One male (the 

 type) in coll. B. Preston Clark, collected by Mr. Emil Kaempfer, August 

 22, 1922. 



This specimen is, I believe, the first representative of the 

 genus Sphinx to be taken in the West Indies. It belongs to the 

 merops-justiciae group, but is shorter- and blunter-winged. Its 

 name has been given because of the brick-red subbasal area of 

 the fore wing above and the blue and white markings of the 

 body and wings.
