64 CLARK — THIRTY-THREE NEW SPHINGIDAE [^ol'.^m' 



This is the second Mexican form of this genus, that I have 

 described, and their discovery suggests the possibility that 

 representatives of this genus may be found farther south, in the 

 mountains of Central America and among the Andes. 



Antennae gray above, brown beneath. Palpi gray irrorated with brown. 

 Thorax and abdomen above, gray irrorated with brown. Legs gray. Abdo- 

 men beneath gray irrorated with brown. Sternites 4, 5 and 6, dark red 

 irrorated with yellow. A minute white lateral dot on each side of the three 

 segments. Cilia black, prominently white between the veins above and 

 beneath. 



Fore wing above: Bluish gray with darker markings. While this color 

 differs markedly from that of G. sonorensis Clark, the pattern of the wing 

 in the two is almost identical, as is the outline of the distal margin. The 

 contrast in color between the light and dark portions of the wing is greater 

 than in G. sonorensis, and the markings are more distinct in character. The 

 stigma is half-moon-shaped and very narrow, convex basad. In this form 

 there is a prominent dark sagittate area, median on the wing, with its bases 

 on the costal margin rather more than half way to the apex, and on the 

 median portion of the inner margin. The point of this sagittate area is 

 onR3. 



Fore wing beneath: Gray irrorated with red, the irrorations becoming 

 heavy toward discal margin. Irregular marginal discal band, bluish gray, 

 3 mm. in width. Stigma present, but straight and less prominent. 



Hind wing above : Bright yellow with black discal marginal band, which 

 is narrower than in G. sonorensis; it is even in width and clearly marked, 

 as in G. hyas Walker. This band contains within it at anal angle a bluish 

 gray patch enclosing a black line parallel to discal margin. 



Hind wing beneath: Bluish gray along inner margin. Distal marginal 

 band also bluish gray, narrow at anal angle and broadening to inner 

 margin. Rest of wing area yellow. A bright yellow band along the anal 

 margin; remaining area heavily irrorated with red, and crossed by four 

 red bands from SM2 to Ml, where they become obscure. 



Antinephele weberi sp. no v.
