3. Ituomia rcECiLA, n. sp. 



d . Expanse 2" 2'". Texture of the wings precisely as in I. Nise ; but both wings are 

 considerably narrower, as in I. Azara. Fore ivlng : above, seniitransparent, with the basal 

 half orange-tawny ; the costal edge, the hind margin, a narrow triangular spot at the 

 Ijase of the cell, and two rounded ones placed obliquely at the end of the cell blackish; 

 the apical third of the wing dusky black, the space between this part and the orange- 

 tawny basal part occupied hy a rather broad, oblique, light-yellow crossbelt ; the inner 

 edge of the black apical part has many indentations, and near the hind angle there is a 

 narrow dusky streak running from the outer margin halfway along the second median 

 branch. Beneath, the same, except that there is a row of 5-6 small Avhite spots very 

 near the outer mai'gin, and a series of \<-o fulvous spots across the dusky-black apical 

 part. 



Ilind whuj semitransparent : above, orange- tawny, with a straight macular stripe along 

 the disk running behind the cell, composed of four semioval spots, which are connected to- 

 gether, and a marginal row of four or live nearly semicircular spots, all black. Beneath, 

 the same, except that the costal edge is yellowish, and that there is a marginal row of six 

 small white spots. 



Body blackish ; thorax spotted with greenish yellow ; abdomen beneath wholly 

 greenish yellow. (Antenmc wanting). 



My example of this species was received from Bogota, Xew Granada. There is a 

 specimen in the British Museum from Xauta, Upper Amazons. 



4. Ituomia Svnnova, Ilewitson. 



JlJiom'ni Si/iiiiova, Ilewits. E\ut. Butt. Ithom'iu, f. lofJ. 



A distinct and beautiful species, found only in the forest at Tunantins, on the northern 

 bank of the Upper Amazons. Its nearest relative is no doubt the following, /. Gunllla.

Ithomla GuiiUlii, Ilewits. Exot. Butt, llliuin'iu, f. 130. 



Found at Fontc Boa, Upper Amazons, flying in company with the two folloAving. All 

 three stand in the closest relationship with each other ; they are identical in colours, 

 differing only in tlieir arrangement or pattern. They all seem to keep themselves 

 perfectly distinct.

This sp('(,'ies has a wider range than the two preceding, being ft)iuid nuich further 

 eastward, at I^ga, and prolialily also west\\ard in Peru. I found, at Ponte ]5oa, Avith 

 the type, a few individuals of a variety which connects the species with /. I'rincilla. I
