The sjiecies united here under Oken's generic term are all closely allie 1 with 

 one another in structure and pattern. They show close affinities to Coclo/iia 

 and Acherontia, and have nothing to do with I'rotoparce (type : rustica), or with 

 riilegrtlwntiii.'s (= ('ocj/fi//.s). 



S2. Tongue very long, strongly thinning apicad. Palinis without cavity in 

 the scaling at the end of (lie first segment externally, second segment about a 

 quarter shorter than the lirst; inner surface of first longitudinally impressed; 

 cavity of second deep, covered by a conspicuous roof of scales (PI. LX. f 1). 

 Antenna almost cipial in width IVom near base to near hook in S , slightly clubbed 

 in ?. Tarsi slender: foretarsns with several prolonged external spines ; mid- and 

 hiudtarsus with basal comb of biistlcs ; posterior tibia longer than first tarsal 

 segment; jjulvillns very small, paronycliium with one lobe at each side instead of two, 

 the smaller ventral lobes obliterated. Scaling of antennae white from base to tip.

 more or less dilated before end (PI. XXVI. f. 15-18), ajicx pointed, compressed ; 

 sternite membranaceous, withont lobe, continuous with the anal cone, which is 

 long. Clasjier sole-shaped, rounded, dilated dorsally before end, this portion curved 

 inwards, inner surface with long bristles, except near apex of harjie, where the 

 bristles are short and stout, s])ine-like. Harpe rather short, with two distal lobes, 

 one above the other, botli curving upwards and inwards, the upper one always 

 pointed, the lower one siiatulatu or also pointed. Penis-sheath much thicker
