58 CLARK — NEW SPHINGIDAE 
Protoparce hannibal mayi subsp. nov. 
Plate VII, figure 2. 
Al. ant. long., o', 51mm.; 9,56mm. Al. ant. lat., 7, 20mm.; 9, 
22 mm. Marg. ext., o', 30 mm.; 9, 32 mm. 
Habitat. — Rio de Janeiro, Brazil. Three males and three females in 
coll. B. Preston Clark, given by Mr. E. May, after whom the species is 
named. 
In size and general facies very similar to P. hannibal. There are, how- 
ever, certain well-marked differences. The light marginal line of the fore 
wing is heavier and whiter; it also is more closely parallel to the distal 
margin as it approaches the apex of wing. The postmedian band of the 
hind wing above is whiter, and less suffused with black, than in P. hannibal; 
this is especially marked in the female. Beneath, the markings are darker 
and more distinct than in P. hannibal, and the double postmedian line of 
the hind wing is more deeply dentate. These differences on the under side 
are more marked in the male.
