7. PERIGONIA STULTA. 
Perigonia stulta, Herrich-Schiffer, 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. Periconia ? Doro. 
Macroglossa doto, Schaufuss, Nunquam Otiosus, i. p. 21 (1870). 
* Africa?” 
If this is a Perigonia the locality is unquestionably wrong, as Dr. Schaufuss suspects 
(believing that Dr. Kaden, 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. PERIGONIA? AFFINIS. 
Macroglossa affinis, Schaufuss, Nunquam Otiosus, i. p. 21 (1870). 
Venezuela. 
Described as a variety of the preceding, and (according to what Dr. Schaufuss says) 
scarcely differing from it. 
Genus 10. Pacuyeonia, Felder. 
Pachygonia, Felder, Reise der Noy., Lep. v. (1875). 
Allied to Eupyrrhoglossum. Primaries with the apex produced and excavated ; inner 
margin deeply excavated below external angle (rendering the angle very acute). Palpi 
less strongly angulated. Antenne 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. 102. no. 4 (1856). 
Perigonia caliginosa, Boisduval, Lép. Guat. p. 66 (1870). 
Pachygonia caliginosa, Felder, Reise der Noy., Lep. iv. tab. 75. fig. 10 (1874). 
Macroglossa gigantea, Schaufuss, Nunquam Otiosus, i. p. 20 (1870). 
2, Mexico (Argent); ¢, Venezuela (Dyson); Paré (Bates). 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 COFFAA, 
Perigonia coffee, Walker, Lep. Het. viii, p. 101. no. 2 (1856). 
Brazil (Stevens) Type, B.M.
