6 ?. Body liiiir yellow beneath ; ventral scales of second segment of [lalpus 

 very long, mostly bnff yellow. Proportional length of tibiae and first tarsal 

 segments nearly as in Coci/titis lucifer. 



$. Tenth abdominal tergitu (PI. XXVll. f 'i'i) strongly compresseil, carinate 

 above, a])e.\ snddenly curved downwards ; sternite very short, reminding one in 

 size and jiosition of that of I'rotopurce triiiiacuJn, the lobe shorter than broad, 

 truncate (PI. XXVII. f. 34), with the angles rounded, (.'lasper not exaggerated 

 in size, as it is in Cocytiua dujjonchel ; harpe (PI. XXXVII. f. 11) resembling 

 that of Protoparce ochus, with a curved ventral process and a flat tlentate upper 

 ridge, no tuft of long bristles upon or near the harpe. Penis-sheatii (PI. XXIX. 

 f. 10) armed with two small teeth, one near the end, the other more ]iro.\imal. 



?. Vaginal plate (PI. XIX. f. 10) laterally recurved, forming rather prominent 

 ridges, mesially convex ; the mouth of the vagina snbapical. 



llah. Tropical (lontiuental America, from Nicaragua to Southern Brazil, 

 probably occurring farther north.

In coll. (Uiarles Oberthiir a fine series from St. Rosa, Colombia ; Guiana ; and 

 Petropolis. In the Museum at Bern from Para (Goeldi). 



The pu[)a figured as that of C. aHtaeiis (—/(ifroiiliiii-) by lUirmeister, De.'icr. 

 Ri'jj. Argent, v. Atlas t. 11. f. 1. 5a. ob (liSTi.)), and wliich we received from 

 St. Catharina is, we believe, that of ^1. walkeri, as it differs remarkably from 

 the pupae of clacntius, (lujwnchel, and antacus, which arc contained in the Tring 

 Museum. It might possibly be that of C. lucifer (= rindaris auct.), but we 

 expect the pupae of lucifer to possess the peculiar rough jiatches found in the 

 other species, and not met with in the chrysalis figured by Burmeister. This 

 fhrysiilis is shorter and thicker than that oi aiitaeux ; the tongne-case is longer and 

 evenly curved, while in antaeu.'i it is nearly straight before the cluljbed end; the 

 rings are high and extend to the middle carina on the underside, while in the 

 pupae of Cocytiua tiie underside has no rings, they extend also closer to the end 

 of the free tongne-case, and each ring is laterally (as well as dorsally and ventrally) 

 interrupted. The rough patch behind the thoracical stigma is indicated, but there 

 are no rouijh iiatcha either on the metanotum or on the abdomen. The cremaster 

 lb Itroad, rounded, terminating iu two snbapical and two apical points. 



The larva and chrysalis figured by Merian, Ins. Sarin, t. 2S, belong possibly to 

 this species ; the clirysalis is certainly not that of dujjonchcl, and it is much too short 

 for (int<icux, though it has, like anfaeus, the tongue-case subapically straightened. 



The larva figured by Burmeister agrees with that of Merian t. 38 in having 

 dark green lateral bands besides the posterior white band which ends at the base 

 of the horn, ll liv<-s on ./iitro///ia. The excrements are small.
