Genus 9. Peeigonia (Herrich-Schaffer), Walker, 

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



1. Peeigonia glaucescens. 



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



Haiti (Tiveedie). ■ Type, B.M. 



Somewhat similar to Macroglossa tantalus. 



2. Peeigonia divisa. 



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

 Cuba (Gundlach and Poei/). 



3. Peeigonia eestituta. 



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

 Perigonia lusca (part.). Walker, Lep. Het. viii. p. 101. uo. 1 (1856). 



Mexico [Hartweg) ; Venezuela {Dyson) ; Pava {Smith). Type, B.M. 



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

 naming the typical form P. interru^ta. 



4. Peeigonia ilus. 



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



" Honduras and Mexico " {Boisduval) ; X 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 Thyveus ahhotii; it would even have 

 been better to have compared it with Lophura continua. 



5. Peeigonia lusca. 



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

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

 Perigonia interrupt a, 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 atrse, fascia magna fulva, quae tamen marginem tenuiorem baud attingit. 

 Angulus aid cinereus, litura fulva. Habitat in Americse meridionalis insulis."' 



6. Peeigonia lefebveei. 



Macroglossa lefebvrei, Herricli-Scliaffer, 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.
