560 MR. H. W. BATES ON THE HELICONIDE LEPIDOPTERA 



Para, and north coast of the isLand of Marajo. Ur. Fckler describes it as a species, 

 from specimens received from the Upper llio Negro.

In this variety the yeUow macular belt is placed close to the end of the cell ; the spots 

 are much elongated, and form, with the yellow spot within the end of the cell, a large 

 compact macular patch. 



Para and Upper Amazons. Neither of these varieties shows a tendency to become 

 local, or separate itself from the parent form.

S 9 . Size, shape, and colour of //. Thelxlope : markings of the hind wing nearly the 

 same as in 11. Vesta. Fore iv/iir/ : above, black, the basal third reddisli carmine ; the 

 nervures bordered with black ; a narrow macular belt, consisting of six light yellow spots, 

 crosses the wing much beyond the end of the cell, nearly reaching the 2nd median 

 branch. Bencaili, the same, except that the red at the Ijase of the wing is scarcely 

 shown. 



llliid loliig : above, black ; the centre of the cell and six narrow streaks radiating from 

 the base, and running between the nervures, but not reaching the margin, reddish 

 carmine ; the second streak from the abdominal edge has a black mark near the base. 

 Beneath, the same, except that the cell has simply two red streaks, that there is a round 

 red spot l)ctwceu the median and abdominal nervures, and that the costa is yellow at the 

 b.ase. 



Body dilferently marked from II. Thelxlope, the thorax being Ijlack, with six distinct 

 rounded yellowish spots and two transverse lines beliind. 



This form seems to be intermediate between U. Melpoiiiei/c and //. Testa. It agrees 

 with the latter in the design of tlu; hind Avings, but the shape and colour of the wings are 

 different from it. In U. T\'sla the shade of red is always inclLniug to orange, whilst in 

 II. EstrcUa it is of the same crimson tint as in II. Ilelpojiicne and Thelviope. This 

 is most perceptible in living sjiecimens. I look upon //. Estrella as a race, or a variety 

 tending to Ijecome a race, equivalent to H. Thel.viupe and II. Vesta, and to have segregated 

 from the common stock, independently of the other forms. 



I met with it only in the I)(>lta lands of the Amazons ; at Para ; and on tlie northern 

 coast of the island of Maraj6.

This species is very al)undant, and widely distrilmted, lieing found at Surinam ; 

 CayeiuK^ ; along tlie Avhole course of the Amazons, up to the Andes ; in Bolivia, and at 

 Cuenca, io tlie west of tli(> CordiHera. It is further removed than II. Thelxlope from 

 II. 31elpoiiieiie, differing from l)oth in colour and in the .shape of the liind wings, their 

 outer margin l)cing less rounded : llu; yellow marks of the thorax are the same as 

 those of //. E--ilrella. The yeUow spots of the fore wing vaiy hi the same way as in 

 7/. Thelx'iojH'.
