76 CLARK NEW SPHINGIDAE [^V^ifm' 



Fore wing above: A dark brown curved postmedian line extends from the 

 wing apex to the inner margin, which it reaches at a point 7 mm. from the 

 base. This line is bordered basad by a lighter line, which extends along 

 the inner margin to the base of the wing. This line diverges slowly from 

 the distal margin, being only 5 mm. distant from it at Ml. The entire wing 

 area basad of this line is olive brown, except that the cell and an area be- 

 tween M2 and SM2 are dark pink. Posterior to this postmedian line is 

 another narrower one, parallel to it, from the wing apex to the inner margin. 

 Two narrow submarginal lines, distant 1 mm. and 2 mm. from the distal 

 margin, extend from the wing tip to the hinder angle. 



Hind wing above: In coloration and in maculation in all respects like 

 that of A^. eumedon, except that the light submarginal band extends qiute 

 to the anal angle, and the dark marginal band is narrower. The peculiar 

 reddish tinge of the light band of X. eumedon extends farther posteriorly, 

 almost to the anal angle. 



Fore wing below: Distal marginal band dull pink, narrowing sharply 

 between R2 and R3. Dark vein dots basad of this band extend regularly 

 from costal margin to inner margin. Basad of the marginal band is a yel- 

 low area irrorated with dark dots. Basal area olive, shading posteriorly to 

 pink, with an ill-defined dark shade extending from the costal margin, at 

 a point 7 mm. distant from the apex, obliquely in the direction of the inner 

 margin, which it does not reach. 



Hind wing below: Very close to X. tersa in maculation: lines, dots and 

 margin. But the ground tone of the entire basal area of the wing is light 

 pink, the marginal band is dull pink, and the median area a lighter yellow 

 than in X. tersa. 



Xylophones josephinae sp. nov. 



AI. ant. long., c?, 40 mm. Al. ant. lat., d', 14 mm. Marg. ext., tf, 

 21 mm. 



Habitat. — Cayuga, Guatemala. One male in coll. B. Preston Clark, 

 given me by my friend Mr. William Schaus, who collected it in July, named 

 after my wife. 



This form is so closely similar in its general coloration to X. damocrita 

 that it might easily be mistaken for it. It is, however, very distinct. 



It is a longer- winged insect. The length of the fore wing, 40 mm., sur- 

 passes, by fully 5 mm., that of any specimen of X. damocrita which has 

 been measured, while in breadth of fore wing and in marginal extent it ex- 

 ceeds X. damocrita by but 1 mm. 



The lines of the fore wing are much straighter than in X. datnocrita. 



Fore wing above: The postdiscal cloud near the apex of the cell is faint. 

 Line 1 starts at a point on the inner margin 5 mm. distant from the base of 

 the wing, is the heaviest line on the wing, and runs almost straight in gen-
