Much smaller than the preceding, which it resembles. On anterior 

 wings the median white band is obsolete, and the subterminal arcu- 

 ated band of whitish semi-transparent spots is reduced to two or three 

 unequal irregular spots towards the middle of the wing. Beneath, the 

 median band is entirely wanting, while the subterminal spots are as 

 on upper surface. The yellowish scales on upper surface of the poste- 

 rior wings in A. Titan are absent, while the costa shows a paler, some- 

 what whitish, shade. The abdomen is paler and the brown terminal 

 segmentary bands are brighter and more reddish than in A. Titan, 

 from which it appears to me perfectly specifically distinct. Two speci-

Aellopos Sisyphus (3Iacro(jlossa Sisi/phns Burm.) from Rio Ja- 

 neiro, belongs to this genus, which is distinct from the European genus 

 Macroglossum . * 



EXTPYRRHOGLOSSTJM, nov. gen. 

 From Macroglossum, with which it has been hitherto confounded, 

 the present genus differs by the larger eyes which are more globose 

 and placed somewhat differently, extending above nearer the antennal 

 insertion. The epicranium is more elevated, reminding us of Enyo. 

 from which the present genus is otherwise sufficiently distinct. The 

 antennae are slender, not prismatic, and terminate in a reflection which 

 is very different from the acute booklet of Macroglossttm. The caputal 

 squammation is dense, rising to a central longitudinal darker colored 

 ridge, recalling Hemeroplanes. The flattened head of Macroglossum 

 and Aellojws has undergone a change preparing us for the more coni- 

 cal and obtuse head of Eni/o and Perigonia. The thorax is more 



* I find that the ornithological resemblances of the European Macroglossum 

 stellatarum have been expressed by different vulgar names. Our species of 

 .Adlojios, bear a certain general resemblance to Procellaria pelagica. So our 

 •• yellow bird" Carduelis tnsiis, finds its miniature and voiceless echo in the 

 yellow Colias.
