J H>99 5 1 CLARK — TWENTY-FIVE NEW SPHINGIDAE 17 



1922 J 



Xylophanes macasensis sp. no v. 



Al. ant. long., d% 40 mm. Al. ant. lat., cf, 16 mm. Marg. ext., 

 c?, 23 mm. 



Habitat. — Macas, Ecuador. One male in coll. B. Preston Clark, re- 

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



Allied to X. ockendeni Roth. 



Antennae brown above, white beneath. Palpi light yellow, shading 

 darker at the tips. Head, thorax, and abdomen above, yellowish olive. 

 Abdominal tergites with two mesial rows of dark dots. Abdomen light 

 yellow beneath. 



Fore wing above: Yellowish olive like thorax, with the three black 

 patches of X. ockendeni, 3 to 5 mm. in diameter, one sub-basal, the second 

 just beyond apex of cell, and the third at hinder margin proximally of 

 angle. A small black stigma. A thin black line from outer side of sub-basal 

 patch to costal edge, curved and irregular. An indistinct black bar in mid- 

 dle of cell. Two faint dentate lines, both dark yellowish green, distally of 

 second patch, extend from midway of the inner margin to SC5, where they 

 merge into two black lines extending from SC5 to costal margin. These 

 black lines, angled basad at SC5, reach the costal margin 12 mm. and 9 mm. 

 from the wing tip. A black dot on costal margin 7 mm. from wing tip. A 

 dark green line extends from the inner margin, at a point 10 mm. from the 

 hinder angle, to the wing tip, curving distally and becoming heavier as it 

 approaches that point. A series of dark vein dots 2 to 3 mm. distant from 

 distal margin. The distal margin evenly convex, except for a slight con- 

 cavity posterior to the wing tip, resulting in a sharper point than in X. 

 ockendeni. Fringe yellowish olive, dark at veins. 



Hind wing above : Brownish black. An ill-defined pinkish band on disc, 

 ending posteriorly in a patch of the same color. Distal edge narrowly bor- 

 dered with yellowish olive. Fringe white, with a dark dot at the end of 

 each vein. 



The under side is similar in pattern to X. zurcheri Druce. 

 Fore wing below: Basal third brownish black; the rest of wing yellow, 

 blotched with orange, and irrorated with longitudinal transverse black dots. 

 An irregular clay-colored distal band, broadest between Rl and R2, where 

 it is 8 mm. in width, extends from wing tip to hinder angle. An irregular 

 dark brown line extends from the median point of the inner margin, curv- 

 ing basad at SC5 to the costal margin, which it reaches 12 mm. from the 

 wing apex. A similar faint line extends from a point on costal margin 9 mm. 

 from apex to SC5, and then faintly to R2. A dark brown line extends from
