32 [September, 



circular tricoloured ocellus just below the angle of the central band ; 

 two sub-marginal bands along the outer margin, the outer one ferru- 

 ginous ; the inner one broader, white, varied with ochreous, intersected 

 longitudinally by a wavy black line ; four deep ochi'eous spots along 

 the apical half of the front margin ; base of front margin rufous. 



Hind-Avings dull chocolate-brown; several indistinct short greenish 

 lines near the base ; a reddish streak at the base of the costal nervure, 

 and another on the abdominal fold ; three small tricoloured ocelli placed 

 obliquely from just below the base of the first submedian nervule to 

 just above the anal angle ; a very small green ocellus between the first 

 and second sub-costal nervviles, outer margin black, longitudinally 

 intersected by two wavy lines of red, varied with yellow, and margined 

 inwardly by a broad, pale ochreous, sub-marginal band, tapering to the 

 anal angle ; interior margin streaked with red and ochreous sub- 

 marginal lines. 



Habitat, Para. 



Closely allied to MorpJio Achilles, Linn. (Amazons, &c.), but 

 differs from it, above, in the broader central band ; below, in having 

 only one ocellus, the central one, on the front wings, but four as usual 

 on the hind-wings ; all the ocelli very small, about one-sixth the size of 

 those in M. Achilles, the uppermost one on the hind-wing being little 

 more than a dot.*

Gen. MEGOPHTHALMUS, Curt. 



Identical with Faropia, Germ., Silb. Eev. t. 1, p. 181 (IS33). 

 Curtis's genus first appeared in the Ent. Mag., vol. I., p. 174 ; and as' 

 the earlier portion of this vol. was published in 1832, the name Megoph- 

 thalmus should stand. The Paropiidce are represented in this country j 

 by a single minute insect, at once distinguished from all others by the i 

 remarkable transverse carinre of the frons, resembling a recumbent J 

 letter X, in the angles of which are placed the ocelli. 



* This species may, of course, bo only a good variuty of M. Achilles, but it is much more distinct I 

 from it than many of tlie species of Morpho, for instauco. Uow does M. Ilelviwr dilfer from M. 

 AchUliBnai May not both those, uiid M. Montezuma also, be only varieties of M Achilles ? The 

 only point in which they seem to diHer materially is in the width of the blue band, a variable charaeter 

 even in this genus, and one that would be scarcely taken into account in any other genus of South 

 American Butterdies.— A. 6. B.
