7. Pebigonia stulta. 



Perigonia stulta, Herrich-Schafiferj Samml. aussereurop. Schmett. fig. 106 (1850-1858). 

 Cuba [Poey). 

 In this species the orange band of secondaries absorbs the entire base of the wing. 



8. Perigonia ■? doto. 



Macroglossa doto, Schaufuss, Nunquam Otiosus, i. p. 31 (1870). 



" Africa 1" 



If this is a Perigonia the locality is unquestionably wrong, as Dr. Schaufuss suspects 

 (believing that Dr. Kadeu, in the dark, labelled it with a blue ticket instead of a green 

 one). The species is said to be allied to P. stulta. 



9. Peeigonia'? appinis. 



Macroglossa affirds, SchaufusSj NTinquam Otiosus, i. p. 31 (1870). 



Venezuela. 



Described as a variety of the preceding, and (according to what Dr. Schaufuss says) 

 scarcely differing from it. 



Genus 10. Pachygonia, Pelder. 

 Pachygonia, Felderj Reise der Nov., Lep. v. (1875) . 



Allied to Plupyrrlioglossum. Primaries with the apex produced and excavated ; inner 

 margin deeply excavated below external angle (rendering the angle very acute). Palpi 

 less strongly angulated. Antennae comparatively rather shorter. Anal tuft of abdomen 

 very broad, short, and dense. 



Type P. subhamata. 



1. Pachygonia subhamata. 



Perigonia subhamata, Walker, Lep. Het. viii. p. 103. no. 4 (1856). 

 Perigonia caliginosa, Boisduval, Lep. Guat. p. 66 (1870). 

 Pachygonia caliginosa, Felder, Reise der Nov., Lep. iv. tab. 75. fig. 10 (1874). 

 Macroglossa gigantea, Schaufuss, Nimquam Otiosus, i. p. 20 (1870). 



2, Me\\co {Argent); c? , Venezuela (%50?i) ; Pai-a (5«^es). Type, B.M. 

 Boisduval's descriptions will of course take priority over Felder's figures, excepting 



(as in the present case) when they are forestalled by those of other authors. 



2. Pachygonia co'efm.m. 

 Perigonia coffate. Walker, Lep. Het. viii. p. 101. no. 3 (1856). 



Brazil {Stevens) Type, B.M.
