J 1922 5 ] CLARK — TWENTY-FIVE NEW SPHINGIDAE 19 



Celerio hippophaes caucasica subsp. nov. 



Al. ant. long., cf , 32 mm. Al. ant. lat., <?, 13 mm. Marg. ext., &, 



18 mm. 



Habitat. — Aresch, Caucasus. Two males in coll. B. Preston Clark, re- 

 ceived from Dr. O. Staudinger and A. Bang-Haas. 



This form is intermediate between the European C. hippo- 

 phaes hippophaes and the Far-Eastern C. hippophaes bienerh. 

 I have been unable to find it described, and am therefore re- 

 cording it. 



In both coloration and maculation, throughout, the inter- 

 mediate character of this form impresses one. In length of 

 wing it is closer to bienerti. The portion of the fore wing 

 above, basad of the dark brown postmedian transverse band, 

 is light yellow, as in bienerti, though less markedly so. The 

 abdomen above is nearly as dark as in hippophaes. The black 

 distal submarginal band on upper side of the hind wing is 

 heavier than in bienerti, being closer to hippophaes. The 

 coloration of both wings below is between that of hippophaes 

 and bienerti, but closer to the latter form. 



Hippotion beddoesii sp. nov. 



Al. ant. long., 9, 35 mm. Al. ant. lat., 9, 13 mm. Marg. ext., 9, 



19 mm. 



Habitat. — Suva, Fiji. One female in coll. B. Preston Clark, collected 



by Mr. Percy Beddoes. 



A beautiful and clearly marked species, resembling most 

 nearly H. velox ab. lifuensis Roth. The silvery lines present 

 in so many species of Hippotion are entirely lacking. 



Antennae gray. First and second segments of the palpi white, third 

 segment grayish green. Head gray, with light pink lateral lines, extending 

 only back of the eye. Thorax and abdomen above, gray. Mesothoracic
