siiorf:, suddenly cnrved downward at apical third, somewhat dilated before this 

 liooic, tij) slinhtly spatiihitc (PI. XXVII. f. 3(1) ; sternite membranaceous, without 

 a Idlie, differing in this respect from all tlie other sj)ecies of Cofyii//.s,as well as from 

 the species of Protojxirci'. 



?. Spination of foretarsus almost normal, row 3 of segment r> dense. Pro- 

 jiortional length of tibiae and first tarsal segments as in S ; first segment of 

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

 in S. Vaginal plate (PI. XIX. f. 8) very much less chitinised than in the other 

 species of Cocj/tins, being for the mo.st i)art membranaceous and almost regularly 

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

 the month 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 

 ])late ; at each side of the vaginal aperture there is a stronger chitinised oblitpie 

 short fold. 



Larva with seveu white obli(|ue stripes, which meet on the back, but do not 

 extend laterally below the middle. — Food : Anona. 



Pupa : tongue-case rolled in, making 2i windings, not strongly ringed, almost 

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

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

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

 with some dispersed punctures ; cremaster narrower than in antaeus.

(??. Owing to an error in the letterpress of BoisduvaPs Plate V., where the 

 present species is named godarti instead of b.'dzehuth, the names of beelzebuth and 



i/odarti have several times been misapplied. The basal and submarginal areas 



of the forewing are greener than in any other species of Coei/tius, 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 ; that cellule is, therefore, somewhat transparent, except 

 towards margin ; a similar i)rocess of reduction is going on in cellule R' — M' ; the 

 hindwing has no transparent ])atehes, but vestiges of such are noticeable between 

 H- and M- close to cell proximally of the band of yellow discal spots. Foretarsus 

 with the comb of sjiines on segments 2 to 5 in S, the comb much less conspicnous 

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

 more distad than in S, Midtibia a little longer than (cJ), or as long as (?), 

 hindtibia as long as (c?), or a little longer than ( ? ), respective first tarsal segments. 



S. Tenth abdominal tergite (PI. XXV II. f 43. 44) elongate, widest in middle.
