CLAKK — TWENTY-FIVE NEW SPHINGIDAE pVoi'.^Viii 



Cocytius macasensis sp. nov. 



Al. ant. long., d\ 67 mm. Al. ant. lat., d", 26 mm. Marg. ext., cf, 

 33 linn. 



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

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



In general appearance distinct from any other known Cocy- 

 tius. Most nearly allied to C. dwponchel and C. lucifer. Its 

 general coloration is seal-brown, with lighter markings. 



Antennae brown above, white beneath. Palpus light yellow at base. 

 Second and third segments rich reddish brown. Head, thorax and abdo-- 

 men above, seal-brown. Mesothoracic tegulae rich reddish brown, tipped 

 with lighter brown. Legs seal-brown, with light markings. Side tufts at 

 base of abdomen prominent, white; abdomen with three yellow side spots, 

 light yellow beneath, except anal tip, which is seal-brown. Hind wing with 

 transparent discal interspaces; transparent areas not indented between the 

 veins. 



Fore wing above, seal-brown, unicolorous. The usual generic markings 

 all indistinct, due to the dark color of the wing. Black streaks R3-M2 not 

 prominent, but clearly defined. Postmedially and costally of veins SC5 to 

 M2 inclusive, are long vinaceous brown markings extending to the distal 

 margin; these are the most prominent characteristic of the species. A 

 prominent yellow dumb-bell-shaped stigma at apex of cell, with an incon- 

 spicuous stigma of the same color distant from it 4 mm. apically and cost- 

 ally. Hinder angle produced as in C. lucifer. Fringe yellow, dark at the 

 veins. Hind wing above, dark seal-brown, yellow basally as in C. lucifer; 

 transparent discal interspaces small; fringe yellow, dark at the veins. 



Fore wing below, natal brown; a yellow streak extends along the costal 

 margin sub-basally some distance toward the wing apex; a yellow patch in 

 the fork between Ml and M2, and another between M2 and the inner mar- 

 gin, basally of the first patch; fringe as on upper side. Hind wing below, 

 natal brown with yellow basal area similar to that on the upper side of the 

 wing.
