M 1923 2 ] CLARK — THIRTY-THREE NEW SPHINGIDAE 67 



The female of this species, so far as I know, has not been de- 

 scribed. In all respects it resembles the male in its facies and 

 markings, and I include it here chiefly because of this fact. In 

 other members of this family differences are to be seen between 

 specimens from Mexico, whence the male of X. juanita was first 

 described, and those from Central America. 



Xylophanes schreiteri sp. no v. 



Al. ant. long., d\ 37 mm.; 9, 37 mm. Al. ant. lat., c\ 12 mm.; 9, 

 12.5 mm. Marg. ext., d\ 20 mm.; 9, 19 mm. 



Habitat. — Tucuman, Argentina. A series of males and one female in 

 coll. B. Preston Clark, collected by Mr. Rodolfo Schreiter. 



This species is close to Xylophanes crotonis zikani Clark, but 

 is in general a darker-colored insect. 



The antennae, thorax, and abdomen above are all a darker green than 

 in X. crotonis zikani. 



Fore wing above: The wing tip is more projected than in zikani. The 

 space between lines 1 and 2 is filled in darkly. This space, as well as the 

 area between it and the costal margin, is darker than in zikani, and darker 

 than the rest of the wing. These two lines and their enclosed area are some- 

 what wavy. These lines, as also lines 3 to 7 inclusive, are curved more 

 sharply distad as they approach the wing apex than in zikani. The yellow 

 basal tuft is smaller. 



Fore wing beneath: The pattern is almost identical with that of X. 

 nabuchodonosor, but the postmedian lines and bars, which in that species 

 are black, are in X. schreiteri rusty red, the entire wing surface being heavily 

 irrorated with this color and with black. 



Hind wing above : Identical with X. crotonis zikani. 



Hind wing beneath: Close to X. nabuchodonosor, but the ground tone is 

 a rustier red than in that species, and the distal marginal band is narrower. 



Theretra cajus ugandae subsp. nov. 



Al. ant. long., d\ 22 mm.; 9 , 23 mm. Al. ant. lat., d", 8 mm.; 9 

 8.5 mm. Marg. ext., cf, 12 mm.; 9 , 13 mm. 



Habitat. — Kibwezi, Kenia Colony. One male and one female in coll. 

 B. Preston Clark, collected by Mr. R. A. Dummer, December, 1921.
