Genus 9. Perigonia (Hemch-Sehaffer), Walker. 

 Perigonia (Herrich-Scliaffer), Walker, Lep. Het. viii. p. 100. gcu. 5 (1856). 



1. Perigonia glaucescens. 



Perigonia glaucescens, Walker, Lep. Het. viii. p. 103. no. 5 (1856). 

 Haiti (Tweedie). Type, B.M. 



Somewhat similar to Macroglossa tantalus. 



2. Perigonia divisa. 



Perigonia divisa, Grote, Lye. Nat. Hist. New York, vol. viii. p. 199 (1867). 

 Cuba {Gundlach and Poey). 



3. Perigonia restituta. 



Panacra restituta, Walker, Lep. Het. Suppl. i. p. 32 (1864). 

 Perigonia lusca (part.), Walker, Lep. Het. viii. p. 101. no. 1 (1856). 



Mexico (Ilartweg) ; Venezuela (Dyson) ; Para (Smith). Type, B.M. 



In the ' Supplement ' Mr. Walker retained the name of P. lusca for this species, re- 

 naming the typical form P. interrupta. 



4. Perigonia ilus. 



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



" Honduras and Mexico " (Boisduval) ; 1 B.M. 



I should hardly call the primaries of Perigonia " sinueuses ; " they are rather waved, 

 but only slightly so. The present species may, I think, be a variety of P. lusca ; I must 

 confess my inability to discover its resemblance to Thy reus ahhotii ; it would even have 

 been better to have compared it with Lophura continua. 



5. Perigonia lusca. 



Sphinx lusca, Fabricius, Sp. Ins. iii. p. 140. no. 5 (1781). 

 Perigonia lusca (part.), Walker, Lep. Hct. viii. p. 101. no. 1 (1856). 

 Perigonia interrupta, Walker, Lep. Het. Suppl. i. p. 29 (1864). 



Guatemala (Salle) ; Haiti (Tweedie) ; Mexico (Argent). Type, B.M. 



There can be no doubt about the identification of this species ; for Fabricius says, 

 " Posticse supra atrae, fascia magna fulva, quae tamen marginem tenuiorem baud attingit. 

 Angulus ant cinereus, litura fulva. Habitat in American meridionalis insulis." 1 



6. Perigonia lefebvrei. 



Macroglossa lefebvrei, Herrich-Schaffer, Corr.-Blatt, 1863, p. 147. 

 Perigonia lefebvrei, id. Corr.-Blatt, 1865, p. 56. 



Cuba (Poey). 



Smaller than the preceding, with no orange spot at anal angle.
