1878.] DIURNAL LEPIDOPTERA FROM CENTRAL AMERICA. 265 



beyond the cell, five argenteous spots surround the margin of the 

 secondaries, whereof those between the lower radial nervule and the 

 third and second median branches are the pupils of black ocelli ; 

 that between the first and second median branches is sagittate. 



$ . Exp. 1'95. Similar to the male, the colour somewhat paler and 

 the wings more rounded. 



Hab. Costa Rica, Irazu (H. Rogers). 



Obs. This well-marked species belongs to the E.-phocion group of 

 the genus (cf. Butler, Journ. L. S. Zool. xiii. p. 123), and comes 

 next E. argentella and E. pyracmon, having the wings similarly 

 shaped. The peculiar tawny-yellow marks of the secondaries render 

 the species very distinct from its' allies. This marking on the upper 

 surface is subject to some variation, being more restricted in some 

 specimens and divided by the reddish brown of the inner portion of 

 these wings running through it longitudinally. Mr. Rogers has sent 

 us a good series of this fine species. 



2. EUPTYCHIA ROGERSI. 



<$ . Exp. 1*9. Form as in E. argentella : uniform brown above, 

 with a single conspicuous black spot near the margin of the second- 

 aries, between the third median branch and lower radial nervule : 

 beneath paler, a dark red-brown sinuate band crosses both wings 

 through the cell of each ; another, nearly straight on the primaries, 

 sinuate on the secondaries, also crosses both wings beyond the cell, 

 outside of which is a pale-brown common band margined exteriorly 

 by a red-brown band hardly traceable on the secondaries ; two 

 argenteous spots near the apical angle of the secondaries, and an 

 elongated submarginal one between the first and second median 

 branches ; a conspicuous ocellus corresponding to the black spot of 

 the upper surface, the outer ring of which is fawn-yellow, and in the 

 black pupil is a concentric silver spot. 



2 • Exp. 19. Similar to the male but rather paler and the wings 

 more rounded ; the dark bands of the underside appear as indistinct 

 reddish bands on the upper surface. 



Hab. Costa Rica, Irazu (H. Rogers). 



This species also belongs to the E.-phocion group of the genus. 

 The presence of a single black submarginal spot on the secondaries, 

 as well as other characters, distinguishes it from its allies E. argen- 

 tella, E. pyracmon, and E. philodice. 



3. EUPTYCHIA VETONES. 



<S . Exp. T8 in. Primaries slightly falcate; outer margin of second- 

 aries sinuate, most produced at the end of the second median branch : 

 uniform brown above : beneath brown mottled with paler scales ; au 

 obscure narrow band crosses the cell of both wings ; a broad sub- 

 marginal pale reddish-brown band, expanding towards the outer 

 margin, on the primaries ; a distinct, yellowish, narrow, nearly 

 straight band traverses the secondaries from inside the apical to in- 

 side l he anal angle ; a distinct ocellus with an argenteous crescent
