In spite of the great differi'uce in the extei-ior, this genus is nearly allied to the palaearctic genus of 

 f'liiimxes, being tiie most nearly allied to the following Polygraplia, \\ liiili is likewise formed by Init one species. 

 The outward ajjpearance is, as the figure shows, so ])eculiar that it is impossibly confounded. 



C. archidona Heir. (J 10 a), the (inly species, has hithei'to been found in Colombia and Peru, but it urch'iiUnui. 

 presumably occurs also in Ecuador and is vei'v rare. The $ discovered by Mr. A. H. Fassl in East Colombia 

 (in March at an altitude of 800 ni) is somewhat larger than the ,5', above and beneath of paler colours and 

 markings, and with a somewhat broader, light yellowish-brown costal-marginal border of the hindwings; all 

 the dai'k markings are likewise scimewluit lighter dark-brown, and the under siu'face with the silvery dots of 

 a still more sti'iking resemlilance with a. faded, bedewed leaf. — magnifica Fnihst. from I'xilivia is considerably iiiitiiii'ii'ini.

As mentioned above, this g(>nus is likewise nearly allied to ('/inni.rc.s which is also expressed already 

 by the outward appearance. But the shape oi; the palps exhibits again an alliance witli Annen, whereby its 

 affinity with Clumixes is manifested again. P. cyiinrn was also at first taken to be a species of Annen. The 

 (lijjerPtire in the structure of the veins, compai'ed «ith that of the genus (if ('linrn.re.^, is but very insignificant, 

 so that Polygriiphn, if its habitat wei'e in the Old Woild. wmdd iirobalily not be separated from C/inrn.rc.<!. The 

 early stages arc still tnd^nown. 



P. cyanea S. and O. (IKia), the only species of this genus, has hitherto been foinid in Ecuador and ri/mini. 

 Peru, and is still considered a gieat rarity. The magnificent blue, silk-glossy I'cflection on the upper surface 

 can scarcely be depicted in the ])ro|)er way. Very contraiy to the u]i})er surface is the plain, striated imder 

 surface which is to be considered as a, j)rotectivc attire. The $ is still unknown to us. and probaljlj' not known 

 at all.

This genus, to which but few specie"-* belong, is likewise chiiracterized already by its dutwiird appeai'ance 

 which is better distinguished by the figures than by words; it is impossible to conf(iund it with other genera. 

 The genus is distributed from Mexico to South Brazil and occurs also in the Antilles. The larva of nemesis) 

 has a sha])e similar to that of the I'/</i(in'i-\:ivx:\v. the pujia being hardly different fi-om that of Annen *).
