Antennae broad and distinct, not transversely ribbed on tbe side of the pectinations as 

 usual in all Lepidoptera, but armed with nearly parallel rows of scraggly, irregular, uneven, erect, 

 slender spine-like minute setae, the rows irregular and with scattered hairs between them. 

 The eyes oval, pointed at each end, surface rough, and on the inside roughened with a dense 

 hedge of bristly erect irregular slender spinules. Between these two hedges are, near the vertex, 

 two groups of similar spines of uneven length; they extend to the ocular hedge, but between 

 them is a smooth valley. 



The pupa differs from any other known to mo in there being no indications of the limbs 

 and mouth-parts, the result of a process of specialization in a direction hitherto unknown to 

 me. Over the site of the interantennal region of the appendages is a broad rough surface, 

 on which are no traces of the. labrum, maxillae or maxillary palpi, as are to be seen in other 

 pupae, as those of Eacles, etc., but the surface is roughened, not divided into areas, and with 

 scattered groups of erect scraggly hair-like setae. By scraping away the crust of the hardened 

 exudation thrown out at the time of pupation, the indications of the legs can be seen beneath. 



The proportions of this interantennal area are as in Eacles, but shorter. The pupa of Eacles 

 is also on the under side of the head and thorax roughened with 'scattered groups of fine flat- 

 tened tubercles, and the surface of the pupal eyes is rough, but in Eudaemonia the little rough 

 eminences of Eacles are exaggerated and tin-own up into erect scraggling setae. 



The abdomen is somewhat flattened, with numerous irregularly scattered minute groups 

 of spinules. On the under side are four large elongated groups of high setae, two on second, 

 and two on the third segment of the abdomen. 



The shape and armature of the end of the abdomen is unique, the end being tridentate; 

 what appears to be the cremaster being a median flattened tooth, broad at the end and covered 

 with long stiff hairs, lying as if fastened to the surface, and directed backward; the end is entire, 

 not forked; on each side, seen from beneath, is a flat, broad, sharp tooth bearing long setae 

 glued to the surface. 



The tergal sides of abdominal segments 9 and 10 are fused into a single piece, the surface 

 and sides of which are rough, spinose, like the rest of the abodmen, but behind the suture divid- 

 ing this terminal section from the rest of the abdomen are two rather large deep rounded pits, 

 with the edges smooth and polished and separated by a similarly polished rounded saddle or 

 bridge. The lateral flattened projections on each side of the cremaster are, seen from above, 

 sharp triangular processes with a mucronate tip. Length 28 mm.
