short, suddenly curved downward at. ajiieal third, somewhat dilated before this 

 liooiv, tip slightly spatnlate (PI. XXVII. f. 30) ; sternite inembranaceons, without 

 a lobe, ditl'ering in this respect from all the other species of CocyUus,as, well as from 

 the species of Frotoparce. 



?. Spination of foretarsiis almost normal, row 3 of segment 5 dense. Pro- 

 portional length of tibiae and first tarsal segments as in S : first segment of 

 foretarsns as long as segments 2 to .5 together, these being much shorter than 

 in d. V^aginal plate (PI. XIX. f. S) very much less chitinised than in the other 

 s])ecies of Cocijtiiis, being for the most part membranacoons and almost regularly 

 fdlded, the lateral edges are stronger ; there is a longitudinal mesial groove from 

 the mouth of the vagina backwards ; within this groove we find a rod-like, smooth, 

 glossy, strongly chitinised, carina, which vanishes near the distal margin of the 

 plate ; at each side of the vaginal aperture there is a stronger chitinised oblique 

 short fold. 



Larva with seven white oblique slripes, which meet on the back, but do not 

 e.xteud laterally below the middle. — Food : Aiionn. 



Pu[)a : tongue-case rolled in, making 2^ windings, not strongly ringed, almost 

 smooth towards apex ; eye more iirominent than in antaeus ; mesonotal and 

 abdominal rough patches .similar to those of antaeus, first abdominal tergite more 

 roughly grooved at the base than in antaexs, eighth segment without patch, only 

 with some dispersed punctures ; cremaster narrower than in antaeus.

(J?. Owing to an error in the letterju'css of Boisduval's Plate V., where the 

 present sjjecies is named yo^A/r// instead of /'/v/.ct'i;////, the names oi beel.:ehuth -awA 



tjodarti have several times been misapplied. The basal and submarginal areas 



of the forewing are greener than in any other species of Cocytius, and there is 

 a green patch distally and costally of the stigma; the scaling in cellule M' — M'' 

 is, on the underside, less dense than elsewhere on the wing, the scales of the upper 

 layer being hair-like ; tliat cellule is, tlierefore, somewhat transparent, except 

 towards margin ; a similar process of reduction is going on in cellule R^ — M' ; the 

 liindwing has no transparent patches, but vestiges of such are noticeable between 

 it- and M- close; to cell proximally of the band of yellow discal spots. Foretarsns 

 with the comb of spines on segments 2 to 5 in S , the comb much less conspicuous 

 in ?, the spines being in this sex more normal in position and direction, pointing 

 more distsul than in d. Midtibia a little longer than (cj), or as long as (?), 

 Iiimltibia as lung as (fj), or a little longer than ( ¥ ), respective first tarsal segments.
