532 ME. A. G. BUTLEE ON THE SPHTNGms:. 



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

 Perigonia (HeiTich-Scnaffer), Walker, Lep. Het. viii. p. 100. gen. 5 (1856). 



1. Perigonia glaucescens. 



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



Haiti (Tiveedie). 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 (Hartioeg) ; 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. interrwpta. 



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 Thyreus abbotii; it would even have 

 been better to have compared it with Lophura continua. 



£ I 5. Perigonia lus ca. 



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

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

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



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



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

 " Posticus supra atrae, fascia magna fulva, quae tamen marginem tenuiorem haud attingit. 

 Angulus ani cinereus, litura fulva. Habitat in Americee meridionalis insulis." 1 



6. Perigonia lefebvrei. 

 Macroglossa lefebvrei, Herricli-Seliaffer, Corr.-Blatt, 1863, p. 147.

Cuba (Poey). 



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