ring, and a series'of decreasing blackish spots from the third yellow spot to the 

 tip of abdomen. Primaries blackish brown, irrorate with gray scales; a grayish 

 patch at base ; basal .space crossed by two indefinite and interrupted, bhick, 

 transverse lines, often not attaining the inner margin. Two more distinct, 

 somewhat approximate and nearly parallel dark lines cross the wing at basal 

 third, strongly angulated above the median vein ; discal dot pale, ringed with 

 blackish at upper edge of cell, a more elongate spot similarly edged at lower 

 angle. At outer third the wing is crossed by two parallel black lines obliquely 

 sinuate, and dentate on the veins ; below the middle a third parallel line becomes 

 visible, distinct to the inner margin, but not traceable to the costa in any speci- 

 men I have seen ; between veins 2 and 3, and 3 and 4, these lines are crossed by 

 a blackish, short, longitudinal dash ; nearer to the outer margin is a very wavy 

 black line, inwardly edged with paler gray or whitish, and parallel to the inner 

 lines, rather less oblique than the outer margin ; an interrupted, very wavy ter- 

 minal line ; a subapical black dash connecting the terminal and subterminal 

 lines. Fringes cut with white. Secondaries brownish black, disc semi-trans- 

 parent, the veins black, base yellow. Beneath, body whitish ; primaries dark 

 brown with yellowish irrorations, most distinct on costa, a yellow patch below 

 median cell. Secondaries with maculation of upper side reproduced. Expands 

 4.50 — a inches ; 113 — 150 mm. 



Hab. — Florida and southward. 



There is no danger of mistaking this for anything else. It is one 

 of our giants, and really a sub-tropical form. INIadame Merian has 

 figured the species in the " Insects of Surinam" as well as the larva 

 and pupa. The larva is clear green, with seven oblique black bands ; 

 the caudal horn is arcuate and rough ; the chrysalis is of a maroon 

 lirown with the tongue-case detached. There is a closely allied, Init 

 smaller species in Cuba, differing from the jjresent by a decided mossy 

 green powdering. It is Poey's A. Dujjoncheli

Body long and slender, wings nari'ow, comparatively short, habitus 

 graceful. Head large, free and prominent, broad, sub-conic, the 

 vertex pilose ; eyes large and salient ; tongue about as long as the 

 body ; palpi reaching the middle of front, pilose, the tei'minal joint 

 sometimes exposed, varying in this, how'ever, in the same species. 

 Antennte with a short, abrupt hook, setose at tip ; ciliate in the S , 

 simple in the 9 . Thorax elongate, well produced before the base 

 of primaries, with a variably prominent, median, divided crest ante- 

 riorly. Abdomen elongate, slender, eyiindro-conic. Legs unarmed, 

 except the ordinary spurs of middle and hind tibije ; increasing in
