J 1922 5 ] CLARK — TWENTY-FIVE NEW SPHINGIDAE 



Sphinx dolli australis subsp. nov. 



Al. ant. long., d\ 27 mm. Al. ant. lat., cf, 8 mm. Marg. ext., cf, 

 13.5 mm. 



Habitat. — Washington Mts., Arizona, thirty miles southeast of Nogales. 

 Two males in coll. B. Preston Clark, collected by Mr. J. A. Kusche, July 17, 

 1919. 



This subspecies is closely allied to S. d. coloradus and S. d. dolli, but is 

 distinct from them both. It is nearest to coloradus. The entire insect 

 is, however, darker in color than coloradus. The head and mesothorax 

 are dark gray. Mesothoracic tegulae are dark brown with no white margins. 



Fore wing above is gray in ground tone, with dark brown markings, in 

 general similar to those of S. d. coloradus. A heavy dark brown line between 

 SM2 and the inner margin, extends from a point 3 mm. from the base of 

 the wing, parallel to the inner margin, and reaches a length of fully 6 mm. 

 Hind wing above is unicolorous, and distinctly darker in tone than in 

 coloradus. Fore wing and hind wing below are distinctly darker in tone 

 than in coloradus. 



Genitalian slides show the clasper more acuminate than in S. d. dolli 

 and S. d. coloradus. The harpe is dentate only on the inner margin. 



Oxyambulyx subocellata chinensis subsp. nov. 



Al. ant. long., cT, 37 mm.; 9, 48 mm. Al. ant. lat., cf, 15 mm.; 



9, 19 mm. Marg. ext., d\ 22 mm.; 9, 28 mm. 



Habitat. — Canton, China. Two males and two females in coll. B. Pres- 

 ton Clark, received from Dr. O. Staudinger and A. Bang-Haas. 



While in all essential respects they agree with typical subo- 

 cellata, when these specimens are placed beside a typical series 

 of the latter certain points of contrast come out sharply; these 

 are especially noticeable in the male. 



Fore wing above: Both sexes lack almost entirely the dark markings 

 of 0. s. subocellata. The various spots and bands are indicated by slightly 

 darkened areas, but all carrying the same ground tone. The stigma, the 

 apical line, and the line at the hinder angle alone are really dark-colored. 

 The stigma is irrorated with white. Hind wing above : Similar in its mark- 

 ings to subocellata, but they are lighter in color.
