cJ ¥ . Scaling of head raised between antennae. Eye not distinctly lashed. 

 Palpus pointed. Antenna slender, not clubbed, seriated ciliae present in ? , but 

 short ; end-segment long and slender, gradually narrowed to a point. Body 

 smooth-scaled ; abdominal tergites with a single row of long, strong spines inter- 

 mingled with small ones ; spines of sternites mnch weaker ; fan-tail of S three- 

 pointed, ? with a long tuft instead. Legs short-scaled, mernm of mid- and hind- 

 coxae not angnlate ; tarsi slender, cylindrical, with the normal four rows of spines ; 

 midtarsus with comb. Forewing sinuate below apex, D' and D' of about the same 

 length ; i5(_!- and R' of hindwing from upper angle of cell, R- in or before centre, D' 

 longer than D*, apex acute. Seventh abdominal sternite of cJ trapezoidal, mem- 

 branaceous distally, without s])ines. 



cJ. Tenth segment divided, the tergite broad, the sternite a narrow belt which 

 is produced into two slender processes (PI. XLII. f 16 — 24 ; XLIII. f. 2. 3). 

 Clasper large, with lanceolate friction-scales ; ventral edge with spines, a patch of 

 spiuiform hairs on inner surface near base ; right and left harpe generally not quite 

 the same (PI. XLVI. f. 11. 17. 18; XLVII. f. 7. 8). Penis-sheath without 

 external armature, or with an obtuse ajncal process, inside with long spines 

 (PI. LIII. f. 25. 26). 



?. Vaginal orifice mesial, surrounded by ridges and folds ; eighth tergite 

 extended to the ventral side (PI. XL. f. 18. 19 ; XLI. f. 6). 



Early stages : Stoll, in Cram., Pap. Ex. Stqipl. t. 22. f. 2, figures a larva which 

 he says is that of //. pan. It resembles very much an Isognathus larva and a 

 younger stage of the larva of Pseudosphinx tetrio. Burmeister, Descr. Rep. 

 Argent, v. At I. t. 23. f. 1 (1879), fignres a similar caterpillar, of which he did not 

 know the imago.
