line. Primaries: the postniedial line is straighter above vein 5 than 

 in RothschikUa liesperus Linna?us, and is not followed above that vein 

 by the lilacine irrorations; the apex is not so falcate as in kesperus 

 male, and the irrorations beyond the postmedial are not distinctly 

 dentate as in hesperus, and aurota Cramer. This is evidently a distinct 

 northern race of hesperios Linnaeus. 



^»/;rt;^>t. — Male, 140 mm.; female, 153 mm.

Genus DYSD^EMONI A Hubner. 

 DYSD^MONIA LEMOULTI, new species. 



Male. — The margins more deeply crenidate than in tamer! an. Male, 

 color greyish brown tinged with green when freshly caught. Prima- 

 ries: the lines line, darker; the two oblique lines from costa near base 

 to inner margin and below vein 2 very much as in ta/merlan; the two 

 outer lines more wavy than in tanierlan or horean., and not thickened 

 or shaded as in the former species; a small transparent spot at end of 

 cell, followed by an irregular large velvety broAvn space; a large tri- 

 angular spot on costa before apex, and a series of submarginal large 

 dark velvety brown spots. Secondaries: the median line not reaching 

 costa; the outer line irregular and angled above vein 3; a large dark 

 submarginal spot below vein 2, and some dark marginal shadings. 



Expanse. — 142 mm. 



Ilahltat. — St. Jean, French Guiana. 



This species is quite distinct when compared with series of tamer- 

 Ian and horeas.^ both of which I have from the Guianas and southern 

 Brazil.

Family CITHERONIID.E. 



Genus EAGLES Hubner. 

 EAGLES GUIANENSIS, new species. 



Male. — Head and collar yellow. Thorax dull violaceous. Abdo- 

 men: two basal segments yellow, otherwise dull violaceous above, 

 yellow below; traces of a yellow subdorsal line. Legs violaceous. 

 Wings yellow. Primaries almost completely suffused with dark vio- 

 laceous, except on costa toward apex and on inner margin on either 

 side of outer line; the yellow portion irrorated with violaceous; two 

 yellow spots at base; the inner and outer lines very broad; the outer 

 margin defined by the absence of stria;; a hyaline spot at end of 

 cell, broadly circled with unstriated violaceous. Secondaries: a basal 

 violaceous irregular band, widening on inner margin and not extend-
