row of white spots on the fore wing is partly obsoh'tc. JJcncalli, it wants (like ,V. luachia) 

 the ycUow sjjot of tlie hind wing at the base of the eosta.

 niodiiiealiuu of .V. y/a/f/(/</, although having a strikingly dillerent appearance through 

 the change in its coloration. It is remarkable that the Cupari form of .V. Ci/ridiicsNa 

 {X. Adelpfic) should have eliaimvd s,, little, whilst X Fi/rois. tln'Cuiiari f.nii of IiincliHf, 

 is so considerably modified from its type.

Tabatinga, neai' the IVontief of Peru, Upper Ama/.ons. 1 believe, with ]M r. Ilewitson, 

 that it is a variety of X. Iiutchhi, but is a well-marked one, the product of a distinct area^ 

 and constant in its differential characters; it merits, therefore, a separate nain(> and 

 mention. I did not meet with it in any other part of the Amazon region, except the 

 locality mentioned above. J )r. i'elder has received it from the I'pper Kio Xeuro. It is 

 similar in colours to the X. sidpliio-uKt (the race of A', litachia peculiar to S. \\. Brazil), 

 but differs from it in the broader black borders and the much paler colour with semi- 

 transparency of the diseal areas of the wings.

Found only at Tonte 15oa, on the Upper Amazons. It mimics \fry curiously in colours 

 and markings a group of Illtom'uc which are peculiar to the .same part of the country, 

 viz., l.yFJid, f. Jllliiissa, I. Prisc/l /a, and T. C/it/iUa. It agr(>es so nearly in all essential 

 characters with A'. I,i"chi(i, notwithstanding the totally dillerent e(doration, that 1 think 

 there can be no doubt it is another local form of that species, in support of this view, I 

 would adduce that it is the only form of the A". 7/^r/r///V'-group found in the locality, where 

 some one or other might be expected to occur, from being f.und al\sa\s in company 

 with Jlltumuc. where these latter (>xist abundantly. I found it ilyiii- aiiioiiL;st a crowd 

 of the above-named species, \\ithin a limited area in the interior of the forest; it was 

 much rarer than the Tl hum id:, i\m\ (piitc undistinguishable from them on the wing.

AgrcH'swith liKicliin in the colour of tlu> body and antenna', but dilfers from it totally 

 in the c(dours of the wings. 11 has a remarkable and evidi'iitly mimetie ri'semblanee to 

 llhoinhi ('ijiiio. JJoth are jjeculiar to the neighbourhood of I'ara — the Uhoiuhi being very 

 abundant, whilst X. Itlirc is an extremely rare species.
